| Abstract: | This work explores the fault injection problem in the
particular case of an implantable capacitive microelectromechanical
pressure sensor for blood-flow measurement
to detect in-stent restenosis. In order to develop a Design-for-Test
method for this MEMS-based sensor and its related electronic
circuitry, an accurate and realistic fault model is essential. A
behavioral description of the equivalent capacitance in the faultfree
case can be obtained from the analytical and numerical
solutions of the deflection of a circular or rectangular diaphragm
under uniform pressure. However, the deflection problem for
faulty conditions due to, for example, contamination-based
defects that cause pyramidal crystals to grow on top of the
membrane must be solved and modeled using finite-element
analysis. |
