The Micro Electro Mechanical Systems (MEMS) density sensor is developed to achieve in-situ measurement of fluid density rapidly. The sensor's sensitive chip with a rectangular microcantilever is fabricated using MEMS technology. In the sensitive chip, an Au coil and four piezoresistors are fabricated on the rectangular microcantilever. When the sensitive chip is placed in the uniform magnetic field...
A novel dc current sensor based on magnetically actuated resonant piezoresistive microcantilever is proposed. The sensor measures the dc current by detecting the shift of resonant frequency of the microcantilever. A detailed theoretical study on the relationship between the current and the cantilever's resonant frequency is also given. To reduce force and displacement noise, the microcantilever works...
This paper presents the design of a novel traction power supply system for urban rail transportation based on multiple-paralleled H-bridge modules. A quasi-sinusoidal voltage output is generated by the novel system with phase-shift control mechanism and the voltage combination of the zig-zag connected transformers on AC line side. As a result, the harmonic components on line side can be greatly eliminated...
