I am a final year university student studying Integrated Engineering at Nottingham Trent University, Nottingham, England, and have little knowledge of the subject of microengineering. I am writing to enquire if you could give me some assistance in my small design assignment. I would appreciate any help you can provide or any links to other people or sources of information. My task is to design a pressure sensor that detectrs pressure change in a pressurised building when a door or window is opened. The sensor must detect a 1.5-psi change and be constructed from a nominal 100mm diameter silicon wafer, with the max size of each die being 10mm x 10mm, maximising the number of sensors from each wafer. Thank you for your time regarding this matter. Yours Sincerly James Morgan _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
