Flexible optical pressure sensor and its application to wearable human motion detecting device

This paper reports a flexible optical pressure sensor based on a porous structured elastomer and its application to a wearable human motion detecting device, which is operated in a self-power-generating way by integrating with an organic photovoltaic cell. Complete investigation of material characteristics and sensing performances as well as optical simulation for understanding the sensing mechanism have been produced. Finally, a self-power-generating wearable motion sensing device was demonstrated as a sensor for detection of flexion and extension motion of a human finger.
