英文摘要	Harnessing random micromeso-scale ambient energy is not only clean and sustainable, but it also enables self-powered sensors and devices to be realized. Here we report a robust and self-powered kinematic vector sensor fabricated using highly pliable organic films that can be bent to spread over curved and uneven surfaces. The device derives its operational energy from a close-proximity triboelectrification of two surfaces: a polytetrafluoroethylene film coated with a two-column array of copper electrodes that constitutes the mover and a polyimide film with the top and bottom surfaces coated with a two-column aligned array of copper electrodes that comprises the stator. During relative reciprocations, the electrodes in the mover generate electric signals of +/- 5V to attain a peak power density of >= 65mWm(-2) at a speed of 0.3 ms(-1). From our 86,000 sliding motion tests of kinematic measurements, the sensor exhibits excellent stability, repeatability and strong signal durability.; Thousand Talents programme for the pioneer researcher and his innovation team; Beijing City Committee for Science and Technology project [Z131100006013004]; Chinese Scholarship Council; SCI(E); PubMed; ARTICLE; ray-han@pku.edu.cn; zhong.wang@mse.gatech.edu; 8031; 6
