This paper reports a novel inertial microswitch with synchronous follow-up compliant electrodes for extending output switch-on pulse width. The flexible movable electrode and stationary electrode are proposed to keep a continuous duration contact by double-stair and spring-shape structures, which can not only extend the output switch-on pulse width but also reduce the impact bounces. Then the inertial...
To improve assessment accuracy, this paper proposes an insulation evaluation model based on an evidence reasoning approach combined with the fuzzy theory, which obtains weights of each parameter objectively and construct the distribution of belief function with uncertainty effectively. Firstly, main insulation parameters for condition assessment are presented, then relevant condition evaluation algorithms...
A piezoelectric MEMS vibration energy harvester with PMN-PT single material has been developed, which can convert low-level vibration energy into electrical energy. Compared with the conventional piezoelectric material, the PMN-PT single crystal has a higher coupling coefficient and electromechanical coefficient, which can improve the conversion efficiency of the power generating device. The designed...
