These smart materials include shape memory alloy (SMA), piezoelectricity, electroactive polymers (EAPs) and etc.
Ionic polymer metal composites (IPMC) is a kind of EAPs and a particularly promising class of actuator materials for underwater microrobots [2-7], since it produces large bending motions under low voltages (1 - 2 V), works well in water and other fluids, and is flexible and biocompatible.

There are two ways can be done: using the materials with higher dielectric constant K and the reduction of the dielectric layer thickness.
In the Duke patent application, the PCB chip production step includes[12]: 1) Select common PCB board as a substrate; 2) Pattern the outermost conductive copper layer of PCB to form electrodes; 3) Using solder mask material (or other dielectric materials) to insulate the electrode; 4) As an alternative procedure， single-step hydrophobic layer can be applied to PCB, in order to promote droplet transmission.
