(a) Schematic illustration of the experimental setup. (b) Sensitivity after repeated loading–unloading cycles at a frequency of 3 Hz. (c) Current response to various pressures. Dot line is a linear regression giving a sensitivity of ~1.14 kPa. (d) Electrical resistance changes under various strains. Gauge factor, GFN could be derived by linear fitting. (e) The durability test under a pressure of 2,500 Pa at a frequency at 2 Hz. The current change curves were recorded after each 10,000 cycles and 200 cycles of data were presented in each recording. (f) Enlarged view of the part of the I–t curve in e after 10,000 loading–unloading cycles.
