Pressure sensors that can both directly visualize and record applied pressure/stress are essential for e‐skin and medical/health monitoring. Here, using a WO3‐film electrochromic device (ECD) array (10 × 10 pixels) and a ZnO‐nanowire‐matrix pressure sensor (ZPS), a pressure visualization and recordi...
