title: Ultra-Stretchable and Force-Sensitive Hydrogels Reinforced with Chitosan Microspheres Embedded in Polymer Networks.
abstract: 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 (102Pa-101MPa) with excellent electrical stability and rapid response speed, potentially finding applications for E-skin.
