This technology involves bonding conductive particles to the surface of an actuator body—made by twisting non-conductive polymer fibers into a coil structure—using a chemical reduction technique. This enables electrothermal actuation via applied electricity and self-sensing of resistance changes based on length variations.
Existing polymer-based actuators suffer from reduced safety due to high operating temperatures (over 200°C), as well as increased weight, bulk, and compromised flexibility in wearable devices caused by the need for separate feedback sensors and mounting components.
This technology imparts conductivity to a body formed by twisting spandex and polyethylene fibers by chemically reducing silver precursors on its surface. It is designed for low-temperature operation (below 80°C) and monitors contraction deformation in real-time by measuring the actuator's own resistance changes, eliminating the need for external sensors. Applicable to robotic gripping, precision measurement, and automated equipment, it improves operating temperature ranges, reduces the need for additional sensors and components, and enhances the monitoring capabilities of fiber-type actuators.
This invention was developed with support from the Ministry of Science and ICT for the development of an in-vivo closed-loop system using electronic sutures for the treatment of inflammatory bowel disease.
This technology is a capsule structure designed for multi-site biological material sampling. It induces active sample adsorption at target locations by sequentially dissolving a pH-responsive outer protective layer and a temperature-controlled inner protective layer (via a heating layer) to expose a polymer layer. It includes a position and orientation control mechanism based on an external magnetic field using a magnetic body housed within the main unit.
Conventional sampling devices rely solely on passive movement via intestinal peristalsis, and their sampling methods depend exclusively on specific pH environments, making precise selective sampling or multi-site discrete sampling impossible.
This technology implements a structure that allows users to sequentially activate specific sampling modules at desired times and locations by applying inner protective layers with different melting points to each module and independently controlling the heating layer of each module through external signal application. Applicable to surgical robots, interventional systems, and medical automation, it provides a non-invasive method, reduces costs, and improves the ability to collect biological materials from within the digestive tract by enabling access to multiple locations within the gastrointestinal tract.
This invention was developed through support for the development of a micro-carrier-based active precision delivery medical device for multi-departmental knee cartilage regeneration.
This technology features a robot device comprising first and second arm units positioned on an arm base and a connecting unit that links them. Each arm unit performs multi-jointed movements through yaw and pitch drive units and a power transmission unit that connects them.
In conventional SCARA robots, multiple independently driven arms are not interconnected, meaning each arm must grasp objects individually, which limits the weight of the objects that can be handled.
This technology secures structural rigidity by coupling the first and second arm units via a connecting unit. By combining and applying the yaw and pitch driving forces of each arm, it improves the ability to grasp heavy objects and enhances locking force. Applicable to industrial robots and automation systems, it increases clamping and locking power while enabling the handling of significantly heavier loads during yaw and pitch movements.
This invention was developed with support for AI-based diagnostic technology and the development of minimally invasive surgical robots for the precision treatment of multi-site vascular bone diseases.
This technology relates to a knee brace for patella stabilization, which includes a first band that wraps around the upper part of the patella, a second band that diagonally wraps around the outer side of the patella, and first and second compression parts embedded in each band that compress the patella.
Existing knee braces only compressed the patella uniformly, leading to insufficient patella alignment and stabilization.
To address this, this technology effectively aligns and stabilizes the patella by using the first compression part to compress the upper patella and the second compression part to diagonally compress the outer patella.
