Design, fabrication and characterization of soft sensors through EGaIn for soft pneumatic actuators

At present, very few soft actuators have achieved strain and pressure sensing capabilities simultaneously. In this paper, one kind of soft strain and pressure sensors based on liquid conductive metal (EGaIn) are proposed, which can be integrated into typical soft pneumatic actuator easily for sensing functions. Here we report design models, fabrication techniques, sensing characterization and sensation experiments for the potential sensors....
