a, The resistance of a single sensing element shows the linear working range (in logarithmic force units). The sensor is not sensitive below about 20 mN of force and saturates in response when a load exceeding 0.8 N is applied. b, Response of three separate sensors in the force range 20 mN to 0.5 N. The sensors show minimal hysteresis (17.5 ± 2.8%; see Supplementary Fig. 2). c, The sensor response after 10, 100 and 1,000 cycles of linear force ramps up to 0.5 N for three separate devices. The resistance measurements are shown in d over the entire set of cycles. e, Differential scanning calorimetry measurements of the FSF material shows a two-polymer blend response with softening/melting temperatures of around 100 °C and 115.1 °C. f, Through-film resistance of an unloaded sensor after treating at different temperatures in a convection oven for 10 min. The film becomes insulating above about 80 °C.
