Abstract
An advanced thick film (ATF) pressure transducer can be produced from an advanced thick film stack on a metallic substrate. The metallic substrate has a flexible metallic diaphragm that flexes when there is a pressure differential across its top and bottom surfaces. The conductive and dielectric layers of the ATF stack are patterned into wire networks and bond pads. A strain sensor can be attached to bond pads or can be formed as part of an ATF layer. Flexure of the diaphragm stresses the strain sensor to produce an output proportional to the pressure differential. The ATF pressure transducer can be packaged into a housing that provides easy deployment and electrical interconnectivity.
