Wireless strain sensor based on poly(ionic liquid) hydrogels. (a) Response signal of calf muscle movement during running and walking. (b) Photographs of the configuration of the wireless sensation system. (c, d, f) Relative resistance changes during jumping, running, and walking under knee bending. (e) Relative resistance changes of the wrist at different bending angles. (g) Photographs of “data glove” mounted with the assembled wireless strain sensors. (h) Relative resistance changes of the data glove responding to different gestures “N, J, T, E, C, and H.”
