摘要：

An ultra-stretchable and force-sensitive hydrogel with surface self-wrinkling micro structure 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.
