This technology features a functional ceramic filter and its manufacturing method. It involves coating the surface of an alumina-based ceramic filter with nano-sized pores with a highly reactive composite layer consisting of metal oxides and layered double hydroxides (LDH). This allows for the simultaneous adsorption and subsequent desorption and reuse of both cationic and anionic heavy metals.
Membrane separation technologies like ceramic filters are durable and generate minimal sludge with little chemical usage. However, they often suffer from low treatment efficiency in high-concentration heavy metal wastewater due to limited surface reactivity and a reliance on physical filtration. Frequent filter replacement is required to maintain performance, and simple metal oxide coatings often face issues with metal leaching or coating delamination.
This technology involves immersing a filter in a first metal solution (magnesium, calcium, iron, etc.), followed by spraying and drying a layered double hydroxide precursor suspension—prepared by mixing first and second metals in a 2:1 to 5:1 molar ratio—and calcining it in a nitrogen atmosphere at 500–700°C. This process creates secondary pores of 13–18 nm, increasing the specific surface area and enhancing the adsorption/desorption efficiency of anionic heavy metals through interlayer anion exchange. Applicable to heavy metal wastewater treatment in plating, smelting, and semiconductor processes, as well as mine drainage, groundwater purification, and industrial wastewater treatment, this method extends filter life and allows for repeated use through desorption.
This invention was developed with support from the Ministry of Environment for the development of high-performance ceramic microfilter application technology for the removal of hazardous heavy metals.
This technology establishes comfort classes for each room by applying both local temperature and humidity comfort standards and international thermal comfort standards. It then analyzes occupant thermal comfort by categorizing temperature and humidity data collected from the rooms based on these classes.
Improving indoor thermal environments typically requires HVAC energy, but excessive consumption leads to increased costs and environmental impact. While countries have their own indoor temperature standards based on climate and demographics, there has been no existing method for hotels with diverse international guests to simultaneously consider regional and international standards to manage both comfort and energy savings.
This technology incorporates regional energy-saving standards to determine energy consumption status by comfort class. It analyzes data only when the room is occupied—specifically when indoor CO2 levels rise above or remain at a threshold during check-in. It also sets target comfort ranges tailored to both domestic and international guest perspectives. The additional or saved energy required to shift between classes is calculated based on the difference in average power consumption of the room's Fan Coil Unit (FCU). This can be applied to hotel and resort room management systems, HVAC operations in accommodations with many international guests, and Building Energy Management Systems (BEMS), allowing for personalized guest comfort while quantitatively managing heating and cooling costs per room.
This invention was developed through the Ministry of Science and ICT's project for the implementation and application support of occupant-centered intelligent shared office facility management systems via living lab-based digital transformation.
This technology is a pelvic support structure that combines linear motors and guide rail-based rotation mechanisms to simulate the three-axis (pitch, roll, and yaw) movements of the human body. It includes a variable width adjustment mechanism to accommodate changes in waist circumference and a strap-based fixation structure.
The limitations of conventional robotic suits include unnatural three-axis rotation due to fixed waist support structures, a lack of flexibility regarding body type variations, and reduced user comfort and fit during wear.
This technology supports upper body rotation through a T-shaped support and a semi-circular pitch guide rail, while connecting the C-shaped support and lower limb supports to allow for roll and yaw rotation. Linear motors are positioned on each axis to provide power assistance, and the system includes a body-type adjustment feature that uses motors to control the distance between the T-shaped support and the side supports.
This technology features an H-shaped upper arm driven by an internal motor and a lower arm connected beneath it, utilizing a guide mechanism (fixing members and guide members) to support and direct the rotation of the arms. Through an encoder-type DC motor and a control unit, the arms can be operated in synchronization or independently, while cushioning members ensure secure object gripping.
Conventional robotic arms suffer from inefficiencies due to complex mechanical configurations and control mechanisms, which increase production costs and lead to significant downtime for repairs and replacements.
This technology simplifies the structure by integrating the drive unit, adjustable connecting members, upper and lower arms, and guide means that support and direct the arm joints, thereby enhancing ease of assembly and control.
This technology features a case mounted on the exterior wall above openings such as balconies. In the event of a fire, gas is injected into a folded mat inside the case, causing it to inflate outward and delay flames from spreading to the floor above.
In high-density buildings like apartment complexes, fire easily spreads from lower to upper floors through openings like balconies, leading to significant loss of life and property. Existing fire-resistant roll screens, while effective at blocking external spread, often cover the entire opening, obstructing firefighting efforts and blocking emergency escape routes via windows.
This technology consists of a first mat body that inflates into a ring shape when gas is injected, and a second mat body equipped with channels for fire-extinguishing fluid, both connected to their respective tanks. The system also integrates a sprinkler, a rotating door, and a rope ladder storage net beneath the case. When the rotating door opens, the seal breaks, deploying the rope ladder to secure an escape route. Suitable for high-rise apartments, office buildings, hotel balconies, and retrofitting older residential buildings, it delays fire spread while simultaneously facilitating firefighting and evacuation.
This invention was developed with support from the Ministry of Education's LINC 3.0 project.
This technology features a smart safety fire door equipped with an airbag recessed into the side of the door facing the frame. Upon pressing a button, an inflation device injects high-pressure gas to expand the airbag, effectively sealing the door gaps. A display and speaker linked to fire sensors provide alerts, while a control unit sends fire notifications to registered devices.
When trapped in a room during a fire, the only option has traditionally been to block gaps with wet towels or clothing while waiting for rescue. Smoke and toxic gases seeping through these gaps are the primary causes of casualties. Existing fire-safe evacuation booths are bulky and impractical for homes or hotel rooms where space efficiency is critical.
This technology utilizes an insertion groove in the door frame connected to a slide hole, allowing a fire-resistant plate to move and seal tightly against the door as the airbag expands. The inflation system consists of a high-pressure gas cartridge and an actuator, with pairs of airbags and inflators installable on both sides of the door. Suitable for hotel rooms, nursing facilities, apartments, and boarding houses, it provides a way to protect a room from smoke with a single button, buying vital time for rescue without needing a separate evacuation space.
This invention was developed with support from the Ministry of Education's LINC 3.0 project.
This technology integrates a fine dust sensor, which measures airborne particles via light scattering, and a control unit into a housing mounted on building ceilings or walls. It functions as an air quality monitor during normal operation and detects fires in real time when smoke particle levels spike.
Conventional photoelectric fire detectors allow airflow caused by fire to enter directly toward the light-emitting and light-receiving sensors through case openings. This leaves the sensors vulnerable to heat damage if initial suppression fails and indoor temperatures rise rapidly. Once damaged, these sensors can no longer transmit critical information regarding fire location or intensity as the fire escalates.
This technology features a cylindrical chamber inside the housing with multiple partition plates extending toward the center. A fine dust sensor is placed between a pair of these plates, which are made of shape-memory alloy that deforms to close around and protect the sensor when heated. By incorporating a temperature and humidity sensor, the system can confirm a fire when smoke detection coincides with a temperature rise. Suitable for hotel rooms, residential units, offices, and smart building IoT safety systems, this device provides both daily air quality management and fire alerts, while maintaining signal transmission longer even after a fire has intensified.
This technology is an electric vehicle fire suppression system that creates an enclosure using a frame and fire-resistant curtains installed in a parking space. When a fire sensor detects a fire, a drive unit rotates the door section to close the front opening, trapping the electric vehicle within an isolated space. A water barrier around the perimeter of the enclosure seals against the floor frame, allowing the fire to be extinguished without water leakage.
Electric vehicle fires involve thermal runaway in lithium-ion batteries, causing high-temperature flames to erupt instantly. These fires require more time, personnel, and cost to suppress than conventional vehicle fires, and in indoor parking garages, they are difficult to approach, making initial response challenging. Existing methods, where personnel manually carry and drape fire blankets over the vehicle, are difficult to execute due to the intense heat and pose a high risk of injury.
This technology is configured so that upon fire detection, a water supply system fills the isolated space, a water level sensor drains excess water, an overhead sprinkler system sprays water, and an exhaust system removes toxic gases. A multi-stage rail frame extends from the pull-out rail to support the fire-resistant curtain of the door section. It can be applied to EV charging zones in apartment and residential underground parking lots, public and commercial parking facilities, and dedicated EV parking towers, isolating burning vehicles from surrounding ones before firefighters arrive to prevent fire spread and the diffusion of toxic gases.
This technology features a rideable structure that supports the user's lower body and includes a saddle. It assists walking by driving a balancing unit, composed of a central actuator and wings, along with two wire-connected pivoting links that simulate hip and knee joints.
Conventional wearable walking assist devices suffer from low power transmission efficiency due to the distance between the power transmission arm and the joints. They are also structurally complex, struggle to assist with standing due to motor capacity limitations, and are prone to damage as loads concentrate on specific mechanical components.
This technology includes a saddle for the user to sit on. A walking actuator mounted on a horizontal support drives two wire-connected pivoting links to simulate the joint structure of the lower limbs, while suspension and tilt/gyro sensors ensure walking stability and shock absorption.
This technology is a lower limb support mechanism using a multi-degree-of-freedom ring-type joint structure. It supports pitch/yaw movement of the knee and roll/pitch movement of the ankle. By placing linear motors at each joint and section, the exoskeleton frame structure allows for length adjustment based on the wearer's body type and provides active muscle strength support.
Existing robot suits face limitations in implementing multi-degree-of-freedom joints due to fixed structures, resulting in poor fit, lack of flexibility in size adjustment for different body types, and issues with peripheral interference and control responsiveness when using hydraulic or artificial muscle actuators.
This technology adopts a ring-type multi-degree-of-freedom structure, incorporating a pitch rotation axis and yaw rotation guide structure at the knee joint, and a C-shaped roll/pitch guide rail at the ankle support. It is configured to actively adjust the lower leg clearance and foot support length using linear motors and connecting rods.
This technology is a wireless control system for an implantable helical microrobot that generates its own power to operate a light-emitting unit by acquiring induced electromotive force from an external magnetic field generator.
Conventional microrobots face limitations in performing therapeutic tasks and tracking their position within the human body due to the difficulty of providing a separate power supply for wireless operation.
This technology features a microrobot with a metallic head and a helical body that rotates and moves in response to an applied external magnetic field. During this process, it generates induced electromotive force from magnetic field changes to power a stacked LED (light-emitting unit). Applicable to industrial robots and automation systems, it improves the ability to position and perform therapeutic actions within the human body using induced electromotive force and wireless operation.
This invention was developed with support from the Ministry of Education, Science and Technology for the development of bio-mimetic biosensors and medical robot convergence technology.
This technology provides a method for multiple slave robots to collaboratively operate a valve using a jig. It features a control mechanism where robots measure valve dimensions to set gripper coordinate systems and then rotate the valve by alternately gripping the jig based on generated paths.
When a single robot lacks sufficient torque or the valve's rotation range exceeds the robot's workspace, remote control of a single unit is limited. Furthermore, manual remote operation of the entire process leads to high operator fatigue and reduced efficiency.
This technology utilizes two or more slave robots to generate motion paths for each unit through a collaborative and autonomous command generation device. While gripping the jig, the robots measure valve dimensions and use this data to rotate the valve by alternately gripping the jig. It includes a safety control function that halts path tracking if excessive force is detected via contact force sensors. Applicable to logistics, service robots, and autonomous platforms, this system enables remote operation of multiple robots, reduces the need for human intervention, and improves overall task quality and efficiency in remote environments.
This invention was developed with support from the Ministry of Knowledge Economy for the development of remote operation service engines and force-feedback remote-controlled robot system technologies for remote tasks.
This technology is a wearable lower-limb robot for gait training on a treadmill. It includes hip, knee, and ankle joints, and specifically features a footplate integrated with a motor and a shock absorber to assist with ankle rotation, as well as a sliding connection to the support frame to facilitate vertical movement during walking.
Conventional gait training devices often suffer from low stability due to complex, non-independent joint control and struggle to effectively prevent foot drop caused by insufficient ankle strength in patients with lower-limb paralysis.
This technology includes a footplate equipped with a motor to drive and control ankle rotation and a shock absorber (spring or gas spring) to prevent sudden movements, a multi-disk shoe link structure that allows for lateral rotation, and a hip joint connection structure that slides along the support frame to assist with vertical movement.
This technology is a system and method for deriving joint stiffness through mechanical equilibrium equations by utilizing the difference in load cell measurements based on changes in human joint (knee) angles and geometric parameters such as leg length and the distance to the center of rotation.
Conventional dynamic model-based stiffness measurement methods suffer from low accuracy due to the difficulty of individually measuring human segment mass and the lack of constant values, as well as the inconvenience of requiring separate external force transducers.
This technology uses an actuator to control the knee angle to create two different equilibrium states. It then calculates individual joint stiffness for each user by inputting the load data measured by a load cell in each state, along with leg length and joint angle data, into a system of simultaneous equations.
This technology is a mechanical driving mechanism for a manipulator moving along upper and lower rails. It incorporates a balance maintenance unit that supports the manipulator's load with an elastic body, combined with a tiltable main arm and auxiliary arm to adapt to uneven ground and distribute weight.
Challenges include the inability of wheeled robots to navigate narrow greenhouse furrows, reduced transport precision due to uneven ground, and structural damage or bending caused by the manipulator's load concentrating on the greenhouse frame.
This technology installs upper and lower rails on the greenhouse ceiling and floor, placing an elastic-based balance maintenance unit between the manipulator and the lower driving unit to distribute the load. It also features anti-slip driving using magnetic rollers, center-of-gravity control via weight adjustment, and a rail groove structure with bearings to enable the extension and tilting of the main and auxiliary arms.
