Ionic polymer-metal composite

IPMC is also known as Ionic Polymer Metal Composite or Compound.

Developed for use as artificial muscles, IPMc can result in a large shape deformation by applying a low voltage (from 1 to 5 volts). Applying a mechanical force to the substance will result in a proportional voltage being applied onto the surface. Because of this it can be used both as a sensor and an actuator.

IPMC is a type of electroactive polymer
