Abstract
EN Triboelectric nanogenerators (TENGs), self - powered devices with a simple structure and high energy conversion efficiency, have gained much attention in recent year. This paper presents a new flexible, high - output, low - cost and self - powered triboelectric adhesive force sensor. Various methods are employed to enhance TENG output. Polydimethylsiloxane (PDMS), with high electronegativity and biocompatibility, is the negative triboelectric layer. PDMS-laden titanium dioxide (TiO2) nanoparticles are used to strengthen its electrostatic induction. An insulation layer on the electrodes stopped electron leakage. For the first time, a pressure - sensitive adhesive is used as the positive triboelectric layer to improve contact electrification. It can fill gaps between contact layers, increasing the contact area and output. The 1 mm thick PTP - PDMS/PSA sensor exhibits an open - circuit peak voltage of 80 V under an applied force of 12 N at 5 Hz, 3.2 times higher than pure PDMS/Al pair, twice that of doped PDMS/Al pair, and 14% higher than PTP-PDMS/Al pair. Through surface patterning and thickness optimization, the PTP-PDMS achieves an open-circuit peak voltage of up to 190 V. This study offers a new practical strategy to enhance performance of TENGs.
