This chapter encapsulates the design and fabrication paradigm of a soft compliant ionic polymer metal composite (IPMC) actuated three-finger gripper material to polydimethyl siloxane (PDMS). The PDMS based IPMC actuated gripper has been designed in such a manner that it is capable of handling macro and micro objects. The selection of PDMS based finger for gripper design was ensured through experiments from four different PDMS finger designs. Maximum compliance of the PDMS finger is desirable for the gripper, keeping this as a criterion, one of the four fingers, has been selected for the presently reported three-finger gripper. In human hand, the proximal, intermediate and distal phalanges activate with each other in a synergistic way through inter-phalangeal articulations. This phenomenon is inculcated using PDMS for compliance in the finger and IPMC as muscle actuation. Overall specification of three finger gripper is reported in this chapter.
