An ultra‐stretchable and force‐sensitive hydrogel with surface self‐wrinkling microstructure is demonstrated by in situ synthesizing polyacrylamide (PAAm) and polyaniline (PANI) in closely packed swollen chitosan microspheres, exhibiting ultra‐stretchability (>600%), high sensitivity (0.35 kPa −1 ) for subtle pressures (<1 kPa), and can detect force in a broad range (10 2 Pa–10 1 MPa) with excellent electrical stability and rapid response speed, potentially finding applications for E‐skin.
