The device is driven by electrostatic force, whereas the Coriolis displacements are transferred to intensity variations of magnetic fields, further detected by the Tunneling Magnetoresistance units. The magnetic fields are generated by a pair of two-layer planar multi-turn copper coils that are coated on the backs of the inner masses. Together with the dual-mass structure of proposed tuning fork gyroscope, a two-stage differential detection is formed, thereby enabling rejection of mechanical and magnetic common-mode errors concurrently. The overall conception is described followed by detailed analyses of proposed micro-gyroscope and rectangle coil. Subsequently, the FEM simulations are implemented to determine the mechanical and magnetic characteristics of the device separately. The results demonstrate that the micro-gyroscope has a mechanical sensitivity of 1.754 nm\/\u00b0\/s, and the micro-coil has a maximum sensitivity of 41.38 mOe\/\u00b5m. When the detection height of Tunneling Magnetoresistance unit is set as 60 \u00b5m, the proposed device exhibits a voltage-angular velocity sensitivity of 0.131 mV\/\u00b0\/s with a noise floor of 7.713 \u00d7 10\u22126\u00b0\/s\/Hz in the absence of any external amplification.<\/jats:p>","DOI":"10.3390\/s20174919","type":"journal-article","created":{"date-parts":[[2020,8,31]],"date-time":"2020-08-31T12:11:19Z","timestamp":1598875879000},"page":"4919","source":"Crossref","is-referenced-by-count":7,"title":["Design, Analysis and Simulation of a MEMS-Based Gyroscope with Differential Tunneling Magnetoresistance Sensing Structure"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9252-2097","authenticated-orcid":false,"given":"Cheng","family":"Li","sequence":"first","affiliation":[{"name":"School of Instrument Science and Engineering, Southeast University, Nanjing 210096, China"},{"name":"Key Laboratory of Micro-Inertial Instruments and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"}]},{"given":"Bo","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Instrument Science and Engineering, Southeast University, Nanjing 210096, China"},{"name":"Key Laboratory of Micro-Inertial Instruments and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"}]},{"given":"Xin","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Instrument Science and Engineering, Southeast University, Nanjing 210096, China"},{"name":"Key Laboratory of Micro-Inertial Instruments and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"}]},{"given":"Xinru","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Instrument Science and Engineering, Southeast University, Nanjing 210096, China"},{"name":"Key Laboratory of Micro-Inertial Instruments and Advanced Navigation Technology, Ministry of Education, Nanjing 210096, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Passaro, V., Cuccovillo, A., Vaiani, L., De Carlo, M., and Campanella, C.E.
