“…Because the proposed device can harvest energy from the stretching motion, it can be positioned on a highly stretchable part of the human body such as joints, shoulders, and waist to obtain high output power. Recently, we proposed a woven piezoelectric structure for the wearable energy harvester and presented the preliminary results of a tactile sensor [31,32]. The power-generating tactile sensor that we propose in this work has a woven textile structure consisting of piezoelectric straps, elastic tubes, and polymer films to provide flexibility and expandability into a large area.…”

In this paper, we propose and demonstrate a power-generating tactile sensor array in which an energy harvester and an array of tactile sensors are integrated in a single device. The device consists of rows and columns of piezoelectric straps woven on a mesh structure of elastic hollow tubes. The fabricated device, which includes 5 × 5 capacitive tactile sensors in an area of 9 × 9 cm 2 , is highly flexible and stretchable. When the device was stretched in a lateral direction, the maximum output voltage and power were measured as 51 V and 850 μW, respectively. In addition, the capacitance value employed as a signal for the tactile sensor operation was measured while applying a force vertically to the surface using a force gauge. The initial capacitance and sensitivity of a single cell employed as a tactile sensor were approximately 1.727 pF and 40 fF/N, respectively, within a force range of 2 N.
