Triboelectric Energy Harvester in Hollow Tube Structure and its Sensor Property

초록

We propose flexible triboelectric energy harvester having a strain sensor property having hollow tube structure. The device was implemented by using flexible silicone tube where the silver nanowire layer is deposited on outer surface. When the tube is pressed or strained in axial direction, output power is generated by triboelectric effect. The output voltage and power of this device was measured as 23.4 V and 201 mu W at 3 Hz. In addition, the device shows a piezoresistive property when longitudinal force is applied, which can be utilized as strain sensor that can be detected by measuring the resistance of the wires.
