Shape-memory ionogels from biodegradable 6PEG-PCL and

conductive ionic liquid (IL) were engineered as wearable electronics for

robot-assisted rehabilitation. 6PEG-PCL was converted to an

elastomer-like material owing to its molecular interactions with the IL,

enabling reproducible and wide-range monitoring of strain variation. Moreover,

the excellent shape-memory property endowed ionogel-based wearable electronics

with geometry-adaptivity to joints, improving the strain-sensing accuracy in

joint rehabilitation.
