Annealing can reduce the residual stress and internal friction loss of materials effectively, thus increasing the Q factor significantly. In this paper, a kind of fused silica cylindrical shell resonator was presented. The design of the resonator, fabricating steps, and the annealing experiment were introduced. A laser Doppler vibrometer was utilized to measure the resonant frequency and the Q factor of resonators before and after annealing. We performed the annealing experiment on three resonators, the best results showed that after annealing, the Q factor increased by 498.3% (from 28955 to 173232, measured in 120Pa).","PeriodicalId":162724,"journal":{"name":"2019 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124980408","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}

This is achieved by applying electronic feedback to control the DC bias across a MEMS capacitor that is to be used in the gyroscope charge sensing amplifier, thereby stabilizing against temperature variations. In this work, a MEMS cantilever capacitor design was used, and the capacitance change was differentially sensed through two pads located underneath the MEMS cantilever beam. A controlled DC bias voltage was then applied to electrostatically return the capacitance to its initial value. Results show that differential changes in capacitance may accurately sense down to 10s of ppm.","PeriodicalId":162724,"journal":{"name":"2019 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128313334","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}

The tradeoff between the ensemble impulse response and the sensitivity is captured by defining the figure of merit (FOM) as the ratio of the squared peak effective displacement of the proof mass to the energy under the ring-down curve. An arrayed accelerometer design is shown to have an inherently higher FOM compared to a single-mass design.

This question arises since the popularity of electric bicycles increases rapidly, which leads to a demand and opportunities for new safety systems. An in-depth analysis of sensor errors is crucial since many of these systems are based on reliable inertial sensor data. This paper shows a method to simulate the full chain of effects from sensor errors to the impact on data fusion outputs, its propagation to bicycle rider assistance systems and finally the resulting riding dynamics. Furthermore, this broad investigation enables the derivation of sensor requirements for inertial sensors that are used for bicycle dynamics measurements.","PeriodicalId":162724,"journal":{"name":"2019 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121577872","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}

While the application space has progressed from the simplicity of compassing to complete geolocation with a priori maps, the extant sensor technologies have plateaued. Each magnetometer platform exhibits at least one nonideal property for navigation applications. For example, fluxgate magnetometers, measuring vector field, suffer from low-frequency drift whereas vapor-cell magnetometers, measuring only scalar field, are insensitive to the field orientation. MIT-LL is developing a novel, absolute vector magnetometer based on the nitrogen-vacancy (NV) color center in diamond. While much of the progress in the diamond community has relied on commercially available material developed for gemstones or electronics, here we develop diamond with NV ensembles tailored for sensing. Although the results focus on magnetometry, they can be applied to additional sensing modalities (e.g. gyroscopes [1], electric field sensors [2], and thermometers [3]). This conference presentation will show enhancement in sensor-based diamond material properties, with over 20-fold enhancement in NV ensemble dephasing times over commercial-off-the-shelf (COTS) diamond. We illustrate how this affects magnetometer performance with respect to applications such as magnetic navigation.","PeriodicalId":162724,"journal":{"name":"2019 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133484323","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}

To tune these frequencies and reduce the frequency split, a voltage can be applied between the shell and electrodes placed around it. This paper investigates electrostatic frequency tuning in shell resonators as a function of voltage, capacitive gap between the shell and electrode, electrode span angle and height, and electrode placement and configuration using a numerical approach. The results of this investigation show that conformal electrodes placed around the shell rim with a uniform gap provide the best tuning capability. Considering fabrication challenges and shell aspect-ratio, other electrode configurations might be more practical in some devices, although they have worse tuning capability.","PeriodicalId":162724,"journal":{"name":"2019 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131099513","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}
