Electroactive Polymers (EAPs) are materials that change shape or size when an electric field is applied. They can expand, contract, or bend, making them useful in various applications, such as sensors, actuators, and artificial muscles. EAPs are lightweight and flexible, which allows them to mimic natural movements. These polymers can be categorized into two main types: ionic and electrostrictive. Ionic EAPs operate through the movement of ions in a gel-like structure, while electrostrictive EAPs change shape due to the alignment of polymer chains in response to an electric field. Both types have potential in robotics, medical devices, and energy harvesting technologies.
