一种新型的自供电人体运动模式探测器刷法制造的高性能纺织基摩擦电纳米发电机

Textile-based triboelectric nanogenerator (t-TENG) has attracted widespread attention because it is the most promising technology in the fields of intelligent electronic textiles and biosensors. However, it is still a challenge for t-TENG with high performance and low cost. Herein, we develop a high-performance t-TENG to harvest biomechanical energy from human motions, in which nanopatterned polydimethylsiloxane (PDMS) – carbon nanotubes (CNTs) film is coated through a novel brush coating method (PCN-TENG). The open-circuit voltage ( V OC ) and short-circuit current ( I SC ) can reach 51.2 V and 3.0 μA, respectively, while the traditional dip-coat method only reaches 14 V and 0.82 μA. Furthermore, the self-powered human motion pattern detector (HMPD) is made, which can collect the energy of human movement and identify the movement status (including: walking, running, and jumping) by inserting PCN-TENG into a pair of insoles insole. HMPD has two working modes, in which mode 1 (the single-electrode mode) is good at recognizing movement mode and mode 2 (vertical contact-separation mode) is more advantageous in collecting movement energy of the human body. In this work, high-performance intelligent electronic textiles were prepared by a novel efficient and convenient method and apply them to t-TENG, which had a high potential for future smart clothing products and self-powered biosensors, and a novel self-powered HMPD had been designed to realize human movement monitoring while collecting energy.
