This technology features a micro-boat fabricated from a silicon substrate. It consists of a first and second substrate bonded together to form a micro-chamber. The propulsion mechanism generates thrust through the reaction force of liquid expelled via a nozzle, driven by the rapid volume expansion caused by the instantaneous vaporization of liquid within the chamber using a heating element.
There is a need to address the limitations of existing electrowetting-based micro-boats, specifically their low movement speeds, short operational lifespans, and the inefficiencies associated with using additional fuel.
This technology places a heating element on the first substrate to periodically vaporize water inside the chamber. By utilizing a hydrophobic surface treatment on the exposed portions of the first substrate, the boat floats on the water surface, allowing it to generate continuous propulsion solely through the circulation of water vaporization and intake, without the need for an external energy source.
This technology is an algorithm that extracts contour coordinates from an input image, groups pixels into objects based on proximity, and identifies discontinuities between objects to control the pen-lifting (jumping) motion of a robot arm, enabling the continuous drawing of discontinuous lines or characters.
Existing drawing robots attempt to draw the entire image continuously after simple contour extraction, which leads to an inability to accurately represent discontinuous contours—such as the strokes in Chinese characters—and results in degraded drawing quality at the connection points between strokes.
This technology consists of an analysis unit that calculates reference coordinates for input data and labels adjacent coordinates to generate a trajectory coordinate list; an object differentiation unit that sequentially compares coordinate positions to group non-adjacent coordinates into distinct objects; and a control unit that lifts the robot arm when moving between objects to navigate to the next starting coordinate.
This technology is a concrete thermal curing system that uses multiple thermal insulation tubes, each containing a space for hot water, laid out across a poured concrete surface without overlapping. The tubes are connected by hot water pipes, allowing the water to circulate and heat the concrete.
In winter or sub-zero temperatures, water within concrete can freeze, halting hydration and preventing proper hardening, which leads to structural defects. Traditional methods like using coal briquette heaters or hot air blowers suffer from significant heat loss, making it difficult to maintain a consistent temperature. Alternatively, embedding heating wires in rebar or formwork carries high risks of circuit breaks, construction delays, and electrical accidents.
This technology features thermal insulation tubes made of waterproof upper and lower sheets, with a low-friction resin layer and a grid-patterned heat-sealing layer inside the upper sheet. When cut to fit the pouring area, the edges are secured using a cylindrical clamp body with a receiving hole and a locking pin to prevent leaks. A one-way plate valve in the piping prevents backflow, while a circulation line equipped with a pump and heater reheats and recirculates the water. Suitable for large-scale concrete surfaces like apartment slabs, bridge decks in cold regions, road paving, and factory floors, this system allows for custom cutting to fit site dimensions, ensuring uniform heating without the risks of smoke or electrical shorts.
This invention was developed with support from the Ministry of Science and ICT for the development of ultra-high-strength, ultra-high-toughness cement composites and micromechanics-based analysis technology considering strain rate effects.
This technology is a rapid reinforcement system for collapsing structures, consisting of a transverse structure such as a beam, longitudinal column structures supporting both ends, a fall-prevention structure placed on guide rails beneath the transverse structure, and power transmission members connecting the longitudinal structures.
Columns severely damaged by typhoons, earthquakes, or terrorist attacks can trigger total building collapse, and due to brittle failure characteristics like buckling, it is extremely difficult to restore their original strength. Existing rapid reinforcement technologies focus on materials and maintenance, such as quick-setting admixtures, anti-expansion mortar, or bridge bearing replacements; there are almost no structural disaster prevention systems that automatically block collapse against sudden, extreme loads like explosions.
This technology transfers the downward rotational force generated when a transverse structure collapses to a spur gear, worm gear, worm, and rotating shaft at the end. The drive and threaded parts of the movable member at the bottom of the shaft pull the fall-prevention structure along the guide rails toward the collapse point. Ball-shaped wheels and guide grooves facilitate movement, a large-pitch threaded section accelerates initial movement, and a cutting part severs the connection member on the side that rotates first, allowing the opposite connection member to wind and pull the support into place. Applicable to large buildings, bridges, underground structures, and critical public facilities at risk of terrorism or explosions, it uses the force of the collapsing beam itself—without power or human intervention—to slide in a replacement support, delaying total collapse and buying time for rescue operations.
This invention was developed with support from the Ministry of Education, Science and Technology for the development of resource-saving, eco-friendly construction methods.
This technology is a marine rock demolition method that breaks rock by inserting a demolition container—consisting of an elastic bag and a threaded watertight sealing cap—into a hole drilled in the marine rock, and then injecting an expansion agent into the container through a hose, rather than pouring the silent chemical expansion agent directly into the hole.
Marine rock demolition has traditionally relied on dynamite blasting or breaker methods, which cause noise, safety issues from explosions, complaints from nearby residents and cultural heritage sites, and disruption to marine ecosystems. Silent chemical expansion agents, an alternative, are typically poured directly into holes and sealed with corks; however, they often fail to perform effectively because they mix with seawater or are washed away by waves, preventing them from hardening properly.
In this technology, a bag with a narrow opening and a wide base is secured to the watertight sealing cap, and an O-ring band on the cap's outer surface adheres to the hole wall to keep the container stable. After injecting the expansion agent through a primary pipe, which forces water out of the hole, the gap is filled with underwater epoxy filler. The pipe is then removed, and a finishing cap is screwed on to seal the unit. This method can be used for harbor dredging, channel expansion, offshore wind and bridge foundation excavation, and removing underwater reefs near cultural sites or fish farms. It delivers expansion force directly to the rock wall without blasting vibrations or noise, minimizing environmental impact and public complaints.
This invention was developed with support from the Ministry of Education for the development of marine rock demolition technology using silent chemical expansion agents.
This technology is a building insulation device that places a case containing phase-change material into the wall cavity of an exterior wall. It features a reflective material—comprising plate-type reflective sections that bounce off radiant heat and plate-type transmissive sections that allow it to pass through—connected in a closed loop around the case and rotated by a power unit.
Phase-change materials have been used for building insulation and energy savings by storing large amounts of heat as latent heat, but they cannot autonomously control the direction of heat absorption and release. Consequently, on summer nights when the outdoors is hotter than the indoors, they release heat accumulated during the day into the interior, which can inadvertently increase the cooling load.
Based on the temperature difference between the indoors and outdoors, the control unit operates the power unit. On summer days, it positions the aluminum reflective section toward the exterior of the wall to reduce the heat absorbed by the phase-change material; at night, it moves the reflective section toward the interior to prevent released heat from entering the building. The power unit consists of an annular belt inside the reflective material, a pair of pulleys on the case mounts, and a drive motor. The case is secured in the wall cavity using protrusions and insertion holes on a base plate, along with an upper bracket. Applicable to exterior walls of apartment complexes and office buildings, zero-energy buildings, and renovations of detached houses in regions with high diurnal temperature ranges, this system actively manages the heat flow of phase-change materials based on the season and time of day, reducing sensible heating and cooling loads while allowing for thinner wall profiles with equivalent performance.
This invention was developed through the Ministry of Trade, Industry and Energy’s project for the development of smart exterior material and equipment convergence technology, the establishment of performance evaluation systems, and demonstration support for the realization of zero-energy buildings.
This technology is a building structure that connects multi-story polygonal core walls and surrounding polygonal perimeter column structures using bracing members placed horizontally at ceiling levels or between two floors. The bracing members are integrated into the primary frame, ensuring they do not obstruct the usable space between the core and the perimeter columns.
In high-rise buildings and apartments, outriggers have traditionally been used to connect the core to perimeter columns to prevent lateral forces from concentrating solely on the core walls. However, floors containing outrigger walls have different structural requirements, which restricts space utilization and complicates construction. Additionally, this creates the problem of lateral moments concentrating on specific floors where outriggers are located.
This technology utilizes a primary planar bracing system that extends from the corners of the core walls toward the corresponding corners of the perimeter column structure. It can be supplemented with a pair of secondary planar braces parallel to the wall extensions and a tertiary planar brace connecting their ends. It can be installed on all corners of a rectangular core across every floor, alternating floors, or at least half of the floors using bars, beams, or structural steel. Applicable to super-tall mixed-use buildings, office towers, high-rise residential complexes, and steel or reinforced concrete structures in high-wind or seismic zones, it allows all floors to be used for residential or commercial purposes without dedicated outrigger floors, while distributing lateral forces evenly across multiple levels.
This technology is a road-based energy harvesting device consisting of a top plate that moves downward under vehicle load, a first sidewall extending downward from it, a second sidewall connected to the top plate via an elastic body with a vertically attached piezoelectric element plate, and a displacement amplifier connecting the two sidewalls, all supported by a support member on the bottom plate.
Existing road-based energy harvesting devices, which generate electricity from vehicle vibrations by embedding piezoelectric elements under the road, offered good durability and prevented road damage. However, they were limited by very low power output because the displacement transmitted from the road surface was too small to sufficiently deform the piezoelectric elements.
This technology positions the support member closer to the first sidewall than the second, allowing the displacement amplifier to rotate like a lever. As the first sidewall moves down slightly, the opposite end lifts or strikes the second sidewall more forcefully, increasing the amplitude of the plate's vibration. The displacement of the second sidewall is determined by the support position and the maximum compression length of the elastic body, while a mass attached to the end of the plate extends the vibration. Additionally, solar panels on the top plate can supplement power generation during the day. Applicable to bus lanes, industrial roads with heavy truck traffic, parking lot entrances/exits, and deceleration zones before crosswalks, this system maintains minimal road surface subsidence while delivering amplified displacement to the piezoelectric elements, thereby boosting power generation efficiency without damaging the road.
This invention was developed with support from the Ministry of Trade, Industry and Energy for the development and demonstration of piezoelectric energy harvesters to utilize untapped road traffic energy.
This technology is a control algorithm for accelerometer-based robotic surgery systems that estimates and isolates physiological tremors in real-time. By integrating Recursive Least Squares (RLS) or a Kalman filter into the BMFLC algorithm, it separates and compensates for conscious movements and unconscious tremors in a single step without the need for a pre-filter.
Existing WFLC algorithms suffer from performance degradation in real-time robotic surgery environments due to issues such as modulated frequency tracking, sensitivity to high-frequency noise, and time delays caused by the use of pre-filters.
This technology improves convergence speed and accuracy by incorporating RLS or Kalman filter operations into the BMFLC weight update stage. It minimizes latency by eliminating the need for pre-filters and ensures that only conscious movements, excluding the estimated unconscious tremor signals, are transmitted to the robot's drive unit.
This technology is a mechanical mechanism that supports the rotation of lower limb joints by combining a cylinder and piston structure with upper and lower braces. It selectively locks the wearer's posture by using a linear motor to mechanically constrain the linear motion of the piston or by blocking the hydraulic flow path.
Conventional lower limb support devices are complex and expensive, and they often fail to provide sufficient support during joint rotation, leading to muscle fatigue for users who work while standing.
This technology connects the upper and lower braces installed on both sides of the lower limb joint with a cylinder-piston device. It uses a linear motor to physically block piston movement or regulate the flow of fluid inside the cylinder to lock the joint angle. Posture locking and unlocking are automatically controlled based on data from motion and pressure sensors.
This technology is a road energy harvesting device where a vibration transmission unit, connected to an open-top housing by an elastic body, moves up and down with road vibrations, causing a rod extending downward to directly press a piezoelectric element or plate surface within the housing to generate electricity.
Existing road energy harvesting devices that generate power from vehicle vibrations by burying piezoelectric elements under the road were durable and prevented road damage, but suffered from very low power output due to the minimal deformation transmitted to the piezoelectric elements.
This technology features a rod unit composed of a protrusion extending from an extension member, with a first and second rod extending from either side, each having different cross-sectional areas or lengths. An actuator rotates the protrusion to select which rod presses the piezoelectric element. Both ends of the plate are secured by fixed parts to increase the bending displacement of the piezoelectric element when pressed, while the movement range of the vibration transmission unit is limited by the elastic body to protect the road and the device. Applicable to highway and arterial road surfaces, toll gates, intersection deceleration zones, and roadside streetlights or self-powered sensor facilities, it allows for switching the pressing rod based on traffic volume and vehicle load conditions to obtain more power from the same vibration.
This invention was developed with support from the Ministry of Trade, Industry and Energy for the development and demonstration of piezoelectric energy harvesters to utilize untapped road traffic energy.
This technology is a revolving door system featuring guide rails with parallel guide holes at the top and bottom of the main body, which has two opposing entrances. The central axis is split into upper and lower shafts, each connected to rotating wings, allowing one shaft to rotate independently of the other.
Conventional revolving doors are slow, making rapid evacuation difficult during emergencies like fires in high-traffic facilities. Panic often leads to people pushing from both sides, obstructing both evacuation and firefighter access. They also hinder the passage of large cleaning equipment or wheelchairs. Existing emergency modes, which flatten the wings, divide the cylindrical space and require manual operation from the center, preventing a swift response.
In an emergency, this technology rotates the upper and lower shafts relative to each other to fold the wings to one side, then slides the entire axis along the guide holes to one side of the frame, creating a wide exit. Normally, the two shafts are locked together via engagement protrusions and grooves, or by rotating an inner shaft to engage/disengage. A sloped drive plate lifts the fixed shaft to assist movement, while wheels on the wing sides provide support. Suitable for department stores, hotels, airports, hospitals, and office lobbies, it allows for a wide passage for evacuees and rescuers without requiring anyone to enter the center of the door.
This technology measures the distance between three RF nodes arranged in an equilateral triangle on the top plate of a master robot and the RF node of a slave robot. By rotating the top plate, it identifies the point where the distances between specific nodes on the master robot and the slave robot become equal, then calculates the relative position of the slave robot using the resulting geometric triangulation and rotation angle.
Conventional technologies for swarm robot localization require the installation of expensive infrastructure or complex sensing devices, such as gyro and ultrasonic sensors, on each individual robot, leading to high data processing loads and increased system costs.
This technology equips the master robot with a rotating top plate and three RF nodes arranged in an equilateral triangle, while minimizing the hardware on the slave robot to just an RF node. Based on the rotation of the master robot's top plate and the distance information between nodes, the master robot precisely calculates the slave robot's position and issues formation commands. Applicable to robot gripping, precision measurement, and automated facilities, this approach minimizes data processing and hardware requirements for a large number of slave robots, thereby reducing overall system load and construction costs.
This invention was developed with support from the Ministry of Education, Science and Technology for the development of public safety smart monitoring and active response technologies.
This technology is a fuzzy logic-based control mechanism that calculates autonomous driving control values by combining positive fuzzy rules for target tracking with negative fuzzy rules for obstacle avoidance. It determines the optimal movement direction (avoidance angle) by applying Gaussian membership functions to obstacle location data detected by ultrasonic sensors and target point information input from a controller.
Conventional remote robot control systems rely on manual user operation, posing a high risk of collision if obstacles are not detected. Furthermore, the lack of integrated autonomous avoidance control technology reduces the reliability of remote operation.
This technology configures a control system that uses the distance and angle between the robot and the target point, as well as the robot and obstacles, as input variables. It applies positive and negative rules respectively, derives the fitness of each input fuzzy set based on mathematical formulas, and calculates the final movement avoidance angle through the computation of output fuzzy set fitness including additive offsets. Applicable to rehabilitation training, gait assistance, and medical/welfare services, it enables self-regulated obstacle avoidance, thereby enhancing the reliability of remote control in robot navigation.
This invention was developed with support from the Ministry of Education, Science and Technology's Biomimetic Robot Technology Development program.
This technology is an assembled steel soldier pile for earth-retaining walls, inserted into drilled holes. It features a C-shaped inner member facing the excavation side, a convex plate-type outer member facing the rear, and lattice members connecting both sides to create an open cross-section.
Conventional H-piles have symmetric cross-sections, making them inefficient at supporting horizontal earth pressure acting from one direction. Additionally, their flanges and webs divide the drilled hole like a partition, complicating the insertion of tremie pipes and often leading to material segregation and poor concrete filling. Previous assembled steel piles also suffered from closed cross-sections, preventing the integration of concrete inside and outside the pile and hindering structural integrity.
This technology uses an arched, triangular, or trapezoidal convex outer member to maximize the moment of inertia within the drilled hole, reducing torsion, deflection, and lateral buckling during installation. Lattice members are arranged in parallel or inward-tapering diagonal patterns, with bent joints attached to the support and outer member. The inner member can be thickened, or longitudinal reinforcements added to the outer member. Suitable for CIP earth-retaining walls on bedrock, deep urban excavations, and temporary structures for parking lots or subway stations, the open cross-section allows concrete to flow freely, ensuring the pile and surrounding concrete act as a single unit against earth pressure.
