This technology relates to an asphalt pavement composition and its manufacturing method, which incorporates fine aggregate impregnated with phase change materials (PCM) and coated with a silica gel thin film via a sol-gel process, replacing a portion of the total fine aggregate.
Conventional asphalt pavements struggle to maintain consistent heat storage performance due to temperature fluctuations, and there have been challenges in stably containing phase change materials within aggregates to prevent leakage.
By impregnating activated carbon with phase change materials and sealing them within the aggregate using a silica gel thin film, this technology ensures that the pavement composition effectively provides heat storage performance without the risk of PCM leakage.
This technology is a mechanical support frame structure that attaches to the lower module of a snake-like robot to increase its contact area with the ground. It includes a seating section, side extension supports, and side-wrapping supports to provide a mechanism that prevents tipping due to shifts in the center of gravity or lateral external forces when navigating slopes.
The issue of insufficient lateral support as snake-like robots increase in length. This leads to reduced driving stability due to a higher risk of tipping when navigating slopes or encountering lateral external forces.
This technology physically expands the ground contact area through an auxiliary member attached to the underside of the snake-like robot. By utilizing the front and rear protrusions of the seating section along with primary and secondary supports, it secures the distance of the support points relative to the center of gravity, thereby improving stability on slopes. It can be applied to logistics transport, service robots, and autonomous driving platforms, improving driving stability on inclines and allowing the snake-like robot to traverse steeper slopes without rolling over.

This technology is a microrobot system that includes a screw part driven by an external rotating magnetic field and a needle part coupled to a base part via an insert structure. Upon reaching the target, the protrusion length of the needle is adjusted through a mechanical groove-and-protrusion locking mechanism to ensure stable fixation.
In fluid environments, microrobots often drift from their target positions due to factors like blood flow. Preventing this typically requires continuous magnetic field control, which leads to reduced control efficiency and high computational loads.
This technology features a mechanical locking structure that houses the needle within the base during transit. Once the target is reached, the needle is extended and its length adjusted by engaging protrusions on the needle's outer surface with grooves inside the base, physically anchoring it to the target. Applicable to surgical robots, interventional systems, and medical automation, this design enhances drug delivery efficiency by increasing dosage capacity and providing an internal storage space within the microrobot.

This technology is a 3-degree-of-freedom microsurgical manipulation and control system that utilizes multiple motors and a linkage structure to perform axial movement (distance/angle adjustment) and radial movement (precision targeting) of surgical instruments.
During retinal surgery, surgical instruments often enter at an acute angle rather than perpendicular to the retinal surface, which increases the risk of retinal damage and errors caused by hand tremors.
This technology implements 3-degree-of-freedom control using three motors. It calculates the coordinates of the surgical instrument tip relative to the target insertion point using angle sensors, a light source (for distance measurement), and an imaging unit to precisely calibrate position and angle. Applicable to surgical robots, interventional systems, and medical automation, it improves control precision and provides users with greater convenience when maneuvering surgical instruments.
This invention was developed with support from the Ministry of Science and ICT for the Multi-Degree-of-Freedom Sensing and Actuation-Based Bimanual Ultra-Precision Surgery Platform project.
This technology is a blood flow velocity management device consisting of a terminal unit that senses blood flow velocity via patches attached to the common carotid artery and radial artery and calculates the difference between the two, and a headset unit that provides auditory stimulation to minimize this difference.
Existing blood flow management methods have limitations in that it is difficult to directly regulate imbalances in blood flow velocity between body parts using audiovisual stimulation, and they fail to optimize stimulation intensity or frequency according to an individual's condition.
By varying the intensity, frequency, and duration of auditory stimulation to identify the optimal conditions that minimize the difference between the two blood flow velocity peaks, this technology can be applied to wearable healthcare devices to improve blood flow velocity imbalances through auditory stimulation alone.

This technology is a vascular management device consisting of a terminal unit that senses blood flow velocity at two points on a single blood vessel using first and second patches and calculates vascular abnormalities based on the difference between the two velocities, and a pad unit that applies electrical stimulation to the vessel when an abnormality is detected.
Existing vascular management methods struggle to quantitatively assess blood flow velocity abnormalities, and even when electrical stimulation is applied, the intensity, frequency, and cycle cannot be optimized for individuals, leading to inconsistent stimulation effects.

This technology features a guidewire microrobot structure that is driven and steered by an external magnetic field. It is sealed by welding or soldering both ends of a hollow tube to a metal body, a core wire, and an external coil, with magnetic materials and flexible substances hermetically enclosed inside.
Conventional magnetic guidewires pose clinical safety risks, such as the potential leakage of internal magnetic particles into the body if the flexible polymer is damaged, or the wire breaking or detaching during procedures due to structural weaknesses.
This technology inserts a metal body into one end of the tube and a core wire into the other, wraps the outer surface with a coil, and then uses welding or soldering to physically seal both ends. This prevents the leakage of magnetic materials and flexible substances while enhancing structural integrity. Applicable to industrial robots and automated systems, the interference fit between the metal components and the coil seals one end of the tube, thereby improving clinical safety and preventing detachment.
This invention was developed with support from the Ministry of Health and Welfare for the development of a microrobotic guidewire system for peripheral vascular intervention.
This technology features a spherical robot equipped with multiple flexible hinge components, each featuring an X-shaped cross-beam or spring structure on its exterior. These components absorb impact from all directions upon impact, while internal links and actuators allow the robot to switch between throwing mode (spherical) and movement mode (separated/rotating).
Conventional throwable robots are complex to manufacture, often combining multiple leaf springs and rubber supports. While they may absorb lateral impacts, they often fail to mitigate vertical shocks, leaving wheels and internal electronic components vulnerable to damage.
This technology utilizes flexible hinge components made of elastic X-shaped cross-beams or springs, arranged in a grid pattern on the spherical housing to ensure omnidirectional shock absorption. A control unit processes real-time speed and orientation data from sensors to adjust internal counterweights, ensuring the shock-absorbing sections are positioned to mitigate anticipated impact points. Applicable to industrial robots and automation systems, this design provides a throwable, small-scale spherical robot with enhanced shock absorption and a specialized housing for movement and rotation, improving upon the monitoring and cost-efficiency of existing robotic solutions.
