Investigated the performances of the highly flexible PGCT when acted as an active sensor under various body movements. a Placed the PGCT on the palm and measured the output voltage at different holding angle (i) 45° (ii) 90° (iii) 180° (fisted) compared to the initial state. b Integrated the PGCT with a wrist brace to measure the output voltage at different wrist bending angle (i) 45° (ii) 90° (iii) 180° as compared to the initial state. c Integrated the PGCT with an elbow brace to measure the output voltage at different elbow bending angle (i) 45° (ii) 90° (iii) 135° as compared to the initial state
