Swimming Microscale Robot with Multi-Fingered Microgripper Structure

Abstract

A swimming microscale robot with multi-fingered microgripper structure was suggested and fabricated for the transportation of micro-objects. The three types of the multi-fingered microgrippers are fabricated using SU-8 that contains 4wt% iron oxide for attaching to the magnetic bead. The bead with the fabricated microgripper was successfully propelled in low Reynold number fluid by the rotational magnetic field using Helmholtz coil system. We are planning the next step to develop active microgrippers which can be remotely actuated.
