Microrobotics technology shows great potential in the field of minimally invasive medicine but still faces key challenges regarding motion control, safety, and cost. Hence, a near-infrared light-response bilayer actuator is designed in this work. The light-driving mechanism and its application in the light-controlled drug release capsule system is deeply explored by taking the double-layer polyvinyl alcohol (PVA)-carbon nanotube (CNT)/polyethylene (PE)-graphene oxide (GO) (PVA-CNT/PE-GO) composi
