The e-skin and its details for training and test. (a) MWCNT-PDMS sheet acting as an e-skin (40 mm × 40 mm). (b) Piezoresistive resistance measurement set up. (c) The wooden bar used for training. (d) A toy finger used for test. (e) A plot of load (displacement or pressure) and electrical resistance as a function of time for a cyclic loading with a frequency of 1 Hz for a uniaxial tensile specimen as given in the right side of the plot. (f) The electrical resistance versus displacement plot for the uniaxial tensile specimen at frequencies of 1, 3, and 6 Hz, showing a complete coincidence. (g) 8 probe terminal electrode signals versus the displacement (pressure) at 6 × 6 sector positions, and a pressure versus displacement curve in the range of pressure from 0 to 1.2 MPa (right side on the bottom).
