Paragraph starter
Electroactive polymers (EAPs) present a compelling material choice for sensing applications due to their inherent electromechanical coupling, enabling them to detect chemical and mechanical stimuli. Their low-modulus, high-strain capabilities and ability to conform to various shapes make them particularly well-suited for the development of flexible, wearable, and biocompatible devices, as reviewed by Wang et al. (2016). This makes EAPs a valuable consideration for design projects requiring advanced sensing functionalities in challenging environments.
