Rational design of self-powered sensors with polymer nanocomposites for human-machine interaction

Smart sensors are becoming one of the necessities for connecting and detecting surround-ing stimuli with tremendous convenience, especially when exploiting a single powerful sensor with multifunctionality. To successfully accomplish the design of a self-powered sensor, serving power is becoming a critical issue because of its continuously consumed energy required by electronics. A variety of nanogenerators aiming for the rational design of self-powered system are reviewed and compared, followed by their recent advances with polymer nanocomposites for self-powered sen-sors. More importantly, the proposed conceptual design of a self-powered unit/device with tribo-electric nanogenerator has been emphasized to eventually realize the practical activities towards multiple detections and human-machine interaction. Finally, challenges and new prospects of rational design of self-powered polymer composite sensors in achieving human-machine interac-tion/interface are discussed.(c) 2022 Chinese Society of Aeronautics and Astronautics.
