MEMS and NEMS

Micro and Nano electromechanical systems can be actuated by potential differences. However Casimir force can influence the dynamical properties and in particular change the stability condition known as jump to contact or snap down. The influence of the Casimir force, ways to reduce it using magnetic fields and aerogels has been a topic of interest. We have consider also actuation using acoustic noise. We are also are studying autonomous devices operated only by chemical changes such as salinity, temperature and concentration of surfactants.
