Pressure Sensors

By altering the properties of materials or components, it is possible to detect various signals. Nano-materials, characterized by a high specific surface area, enhance the sensitivity of sensors. We utilize high dielectric materials, high-conductivity materials, highly absorbent materials, variable resistance materials, and biomimetic structures in the fabrication of pressure sensors.

After molding the leaf veins and affixing them onto thin films, we apply them to the electrodes of pressure sensors. Additionally, we collaborate with Professor Fu-Yu Chen from the Department of Biomedical Engineering at Chung Yuan Christian University to jointly develop insoles for the treatment of Sarcopenia.
