Novel prognostic sensors and reasoner algorithms are the core technology for detecting defects caused by accumulation of fatigue damage in electrical and mechanical systems over time. However, serious technical challenges to implementing a general health management strategy for helicopters and military aircraft still exist. For example, severe heat and vibration make it difficult to distinguish fault...
The production of useable energy is today a global issue and the search for alternative energy sources is very challenging. Therefore, scientists have' tried hard to identify new alternative energy sources. Fuel cells have potential as an indispensable source of electrical power. However, the mass production of fuel cells encounters various problems, which are yet to be solved, such as determining...
Poly-crystalline silicon carbide (polysic) Micro-electromechanical systems (MEMS) capacitive pressure sensors operating at harsh environments (e.g. high temperature) are proposed because of SiC owing excellent electrical stability, mechanical robustness, and chemical inertness properties. The principle of this paper is, design, simulation. The application of SiC pressure sensors are in a harsh environments...
In order to satisfy the different packaging requirement of individual sensors in the monolithic multi-sensor chip, a hybrid packaging method is presented in the paper. The packaging method of multi-sensor makes use of high-resolution stereolithography system of photopatternable resin constructing the main packaging structure in the way of batch production, low cost and good resolution. A monolithic...
