Hi This is very non trivial. First you have to make sure you don't have edges or surface defects that act as field conetrators. Then you have to find the Paschen curves for air and argon at the pressure and temperature you plan to work at. shay -----Original Message----- From: mems-talk-bounces@memsnet.org [mailto:mems-talk-bounces@memsnet.org] On Behalf Of ashwini jambhalikar Sent: Friday, October 12, 2007 7:17 AM To: mems-talk@memsnet.org Subject: [mems-talk] breakdown voltage in MEMS structures Friends, can somebody give me some reference about following problem: if the gap between two electrodes,is 5 micron / 8 micron/10 micron what voltage can be safely applied for electrostatic actuation, considering air or argon or nitrogen as dielectric.
