It is more than a decade that Ionic Polymer-Metal Composites (IPMCs) have been known as an exciting class of smart materials and attracted growing worldwide attention. IPMCs are soft and flexible, and can generate large and reversible strains in response to electrical stimulus. …
Microelectromechanical systems (MEMS) are considered as potential candidates for "More-Moore" and "More-than-Moore" applications due to their versatile use as sensors, switches, and actuators. Examples include accelerometers for sensing, RF-MEMS capacitive switches in communicat…
