Electroactive polymers (EAPs) are special materials that change shape or size when an electric field is applied. This unique property makes them useful in various applications, such as soft robotics, sensors, and actuators. EAPs can mimic the movement of muscles, allowing for more flexible and adaptable designs in technology. These polymers can be divided into two main types: ionic and electronic. Ionic EAPs work by moving ions within the material, while electronic EAPs rely on changes in electrical charge. Both types are being researched for their potential in creating innovative devices, from artificial limbs to advanced medical equipment.
