Current microscale grippers are controlled by external pneumatic, hydraulic, and electrical signals. Many also only operate under limited conditions (non-aqueous media, high temperature, ionic solutions). Their tethered nature and operational restrictions limit their versatility and often preclude use in biomedical applications. There is a need for minimally-invasive tools that can perform tasks, such as tissue biopsies without the need for batteries or wiring. In this poster we present a novel gripper that can perform such tasks in an environment that is viable for living organisms.
