polymers (EAPs) are emerging smart materials that can generate large deformations under electrical stimuli. EAPs have a built-in sensing and actuation mechanism which enables them as sensors and actuators. EAPs have difference configurations which can be divided
into two categories: ionic EAPs and electronic EAPs. Ionic polymer metal composites (IPMCs) are one type of ionic EAPs which can generate large bending motion under wet conditions. Dielectric elastomers are one type of electronic EAPs which can generate large
contraction force under high voltage stimuli. In this talk, we will explore the mechanism, modeling, sensing, fabrication, and application of IPMC and DE. This presentation will be organized as follows. Fabrication of IPMC will be discussed first. Physics-based
and control oriented-modeling of IPMC actuator will be discussed second. Third, bio-inspired underwater robots enabled by IPMC will be presented. Fourth, fabrication, modeling, control, and self-sensing of DE actuator will be demonstrated. Last, advantages
and potential challenges of EAPs will be discussed at the end.</span><o:p></o:p></p>
