Hi all, I am a new member of this group. My name is Atul and I am a graduate student at University of Texas at El Paso. Could anyone please tell me the necessity of miniaturizing parts which already exist? Re-phrasing my question I am not clear about the reason for existence of MEMS. Thanks for your time and looking forward to someone replying. Atul. "Success never rests. On your worst days, be good. And on your best days, be great.
