> Hello: We need to make a rectangular elastic corrugated membrane (less than 1 mm on each side), which has a displacement of about 40 micron under a pressure of 300 mmHg.The more tricky part is we need a wall (about 200 micron tall) attached to the center of the membrane. Anybody can offer advice about the materials, process, or available facilities? I will really appreciate your help. Yuping Lin Tel: (248)960-3523 Fax: (248)960-1814
