a A custom sensor morphology is printed directly onto the surface of a nitrile glove. b All five fingers of the glove return separate strain responses, enabling proprioceptive data to be inferred. c A cast PneuNet actuator demonstrates the healing of a scalpel cut after 30 min at room temperature and after a small amount of manual reheating. The actuator is pictured 2 and 5 months after casting.
