フレキシブルセンサによる振動応答計測

抄録

Many types of flexible and stretchable sensors, which can be used to measure strain and pressure, are applied to various devices. A dielectric elastomer sensor (DES) is flexible and stretchable, which has been attracting much attention in recent years. In this study, we measured the response of vibration in the DES and characterized the performance of the DES. The response of a vibration in a circular membrane-shaped DES was limited to up to 10 Hz experimentally. In this experiment, we fabricated a DES using a PDMS membrane as a silicone elastomer and carbon powder as stretchable electrodes. We used an electromagnetic shaker to vibrate the DES. We then recorded the capacitance value using the LCR meter. We found that the DES responded to the vibration up to 10 Hz. Our DES would lead to new applications.
