Electrostatic Actuation. Actuators based on thin membranes find applications in microelectromechanical systems (MEMS), as optical devices, and sensors. In most cases, actuation in MEMS is based on electrostatic forces. Previously, we studied the electrostatic application of membranes from crosslinked gold nanoparticles and their application as sensors for volatile compounds. Here, we turned the initially insulating TNR/GO/SF membranes into conductive TNR/(rGO/GO)/SF membranes by DUV exposure (Figure , Supporting Information) and explored their electrostatic actuation.
