|Abstract:||This work explores the fault injection problem in the particular case of an implantable capacitive micro-electromechanical 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 fault-free 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.|
