1. Fig. 3 Touching while stretching and bending.
Touching while stretching and bending. (A) Plot showing the recorded displacement (7% strain) and capacitance of a single taxel in the sensor while being stretched by a sinusoidally varying displacement using a dynamic mechanical analyzer; the sharp drops in capacitance coincide with touch, while the sinusoidally varying changes are the result of the stretching. (B) Sensor in steady state. (C) Stable capacitance map for steady state. (D) Sensor folded in an anticlockwise direction. (E) Resulting small positive change in capacitance of the taxels along the axis of bend where capacitance increases with positive y axis. (F) Sensor being touched while being bent. (G) Negative change in capacitance map showing the taxel touched having a change in capacitance of 10%, reduced slightly by the change due to the bend where the capacitance decreases with positive y axis. (H) Sensor being bent in the clockwise direction. (I) Positive change in capacitance map showing the axis of bend and a similar response to that in (E).
