Rezorewstlve sdlcon-based pressure sensors have been fabncated which are capable of hlghpreclslon operation at temperatures as high as 250 "C These devices are fabncated by a umque &con fusion bonding process m which resistors from one wafer are bonded to the oxldlzed surface of a second wafer The m
A di erential ΓΏber Bragg grating (FBG) sensor with a free active element bulk-modulus for high-pressure (or displacement) measurement is presented. Based on the di erential measurement method and an isosceles triangle cantilever structure, problems of cross-sensitivity and chirped signal in FBG sens
