System and apparatus for sensing pressure in living organisms and inanimate objects

摘要

System and apparatus for measuring pressure comprising a microelectronic device (24), an interface member (14) attached to the microelectronic device, a pressure sensor (12) having a diaphragm (16) responsive to external pressure exerted upon the diaphragm, wherein the interface member (14) is positioned between the microelectronic device (24) and the pressure sensor (12) and is attached to the pressure sensor providing a first cavity (13) between the pressure sensor diaphragm (16) and the interface member (14) and wherein the pressure in the first cavity is set at an initial predetermined pressure.
