摘要

This paper presents a power-generating sensor array in a flexible and stretchable form. The proposed device is composed of a woven structure that provides various features, including a capacitive tactile sensor, piezoresistive strain sensor, triboelectric energy harvester, and piezoelectric energy harvester. The device is implemented in a textile structure using functional threads implemented with lead zirconate, carbon nanotube, polydimethylsiloxane, and silver nanowire (Ag NW). A stretching force can be detected by measuring the resistance change in the Ag NW composite layer on each thread. Further, the magnitude and location of the vertical force can be detected by measuring the capacitance variation on each capacitive cell that is formed by the gap between two Ag NW layers at the crossing points of each weft and warp thread. For the energy harvesters, the maximum power was measured as 108 mu W at 3 M omega from the triboelectric energy harvesting when the device was pushed in the vertical direction. When a stretching force was applied, a maximum of 60.3 mu W at 1 M omega was measured from the piezoelectric energy harvester.
