Microelectromechanical devices have been developed, fabricated and optimized, which are based on multiple capacitances with a common movable electrode. By applying a voltage to one capacitance, a force is generated which is translated into mechanical motion, eventually balanced by the mechanical spring counterforce of the suspension. Operating the device at frequencies above mechanical resonance allows the RMS value of the signal to be measured, supplementing conventional methods. For DC and RF voltage excitation, the resolution has been enhanced to be better than 0.1%. The usable frequency range has been extended beyond 10 Megahertz at RMS voltage levels of less than six volts. Furthermore, a model applied for dimensioning the sensors is presented focusing on high-frequency metrology aspects. By evaluating the frequency dependence of the design parameters, predictions of the measurement range and resolution of the final structures can be made.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124033274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It consists of a 1 mm diameter octagonal spiral inductor and a micro fabricated MIM (metal insulator metal) capacitor. Polyvinylidene Fluoride-Trifluoroethylene (PVDF-TrFE) copolymer is applied as a dielectric material for the capacitor fabrication due to its high dielectric constant. The 1 mm diameter, 154 nH spiral inductor is built on top of the capacitor. The capacitor and the inductor are in parallel connection through SU8 via holes. SU8 is used as a packaging material due to its biocompatibility, and also it serves as an insulator between the capacitor and the spiral inductor. The operating frequencies of the LC tanks are decided by the sizes of the capacitors (45 × 45, 55 × 55, 95 × 95 and 100 × 100 µm), and measured operating frequency range is from 385 to 485 MHz.

In most gyroscope systems, the rotation angles were obtained by integrating the angular rate, thus suffer from the error accumulation problem. Only a few papers reported that they could compensate the imperfect dynamics in gyroscopes and obtain the rotation angle directly. However, they either required a calibration phase prior to the normal operation or their stability was not theoretically proven. This paper proposes a one-step control algorithm so that imperfection compensation and angle measurement can be done simultaneously. In a demonstrating case, the mechanical structure uncertainties caused 10%∼20% parameter variations in a gyroscope system; the signal are contaminated by zero-mean white noise with the PSD of 2.3×10−15(ms−1)2/Hz; the angular rate to be measured is 4sin(2π × 40t) rad/sec. The proposed algorithm can obtain the rotation angle with an accuracy less than 0.5 degree.","PeriodicalId":262591,"journal":{"name":"2009 IEEE Sensors","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129341272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
