A stretchable resistive pressure sensor is achieved by coating a compressible substrate with a highly stretchable electrode. The substrate contains an array of microscale pyramidal features, and the electrode comprises a polymer composite. When the pressure‐induced geometrical change experienced by the electrode is maximized at 40% elongation, a sensitivity of 10.3 kPa −1 is achieved.
