Triboelectric mechanical sensors—Progress and prospects

Abstract

The development of sensing technologies has increased the intelligence level of equipment. It is difficult for traditional sensing technologies to meet many current application requirements, such as complex trajectory monitoring, flexible manufacturing or other fields. Triboelectric nanogenerators were first invented in 2012 and have revolutionized energy generation and sensing. Triboelectric sensors have a variety of structures, which have promoted their applications in the field of internet of things, biomedicine, intelligent transportation and motion sensing or something. The development of triboelectric nanogenerators in machinery industry has attracted wide attention. This review covers recent progress in the development of triboelectric mechanical sensors for monitoring mechanical motion, mechanical vibration, mechanical pressure and mechanical tactile perception. The prospects of triboelectric mechanical sensors are then summarized.
