As demands of microrobots increases, micro-actuators for lhe microrobots are actively studied. However, miniaturized motors cannot be easily applied 10 microrobots owing to lhe limitatioJ1s of lheir sizes antd generating forces. Therefore, a new smart material for microrobots should be developed. A mong various smart materials, such as PZT, SMA, Ferrofluid, we focused on a ferropaper actuator using ferrof1uid. The ferropaper actuator is regarded as a smart mater ial and can show large displacemenls, excellent repetilion perfonnances, and relative small actuation forces. In lhis paper, a cellulose is used 10 make a backbone membrane because il has superior properties compared with any others conventional papers. The cellulose paper backbone membrane is easily fabricated as complex shapes and shows a large displacement in a magnetic tield. In detail, patterned ferropaper actuator is made of cellulose acetate using general MEMs procedure and PDMS molding method. Finally, through EDS mapping and alignment experiments of the làbricated ferropaper actuator using an electromagnetic actuation (EMA) system, the patterned ferropaper actuator was characterized.
