 A multi-responsive actuator with self-sensing function is developed using emzene-coated paper and polyethylene, which can be triggered by multiple stimuli, perform large deformation with low power consumption but high response speed, and detect its own deformation for environmental monitoring and smart gripping applications in soft robotics, intelligent switch, and bionic prosthesis.
