Abstract
Implantable pressure sensors and methods for making and using the same. A feature of at least some of the subject pressure sensors is that they are low-drift sensors. Additional features of representative pressure sensors include the presence of at least one strain transducer that is fabricated from a stable gauge material. The subject pressure sensors find use in a variety of applications.
Claims35
A pressure sensor structure comprising:
- a substrate;
- a compliant member mounted on said substrate in a manner such that said compliant member has first and second opposing exposed surfaces;
- and
- at least one strain transducer mounted on a surface of said compliant member, wherein said at least one strain transducer is separated from said surface of said compliant member by a spacer;
- and
- wherein said structure has a sensitivity sufficient to measure pressure changes of about ±1 mmHg.
