This technique uses the strong points of the powerful ablation of cavitation as well as plasma irradiation. The novelty of the technique enable to process not only conductive material but also non-conductive material such as polymer, CFRP (carbon fiber reinforced plastic) and silicon, which is unlike conventional wire electric discharge machine. Also, the directional transportation of bubbles provides positioning accuracy of micro-processing. The structure of the plasma-cavitation pencil cutter is low cost and very simple structure. This technology contributes to effective processing of wide range of materials such as metal plate, polymer, carbon-fiber and biomaterials.","PeriodicalId":6465,"journal":{"name":"2015 Transducers - 2015 18th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87546090","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}

A theoretical model has been developed and substantiated by ANSYS simulation. Results show good agreement with both simulation and modeling. The out-of-plane deflection is 24μm at 6V/μm electric field with a maximum Deflection Sensitivity to Voltage (DSV) of 0.5μm/V. The unloaded resonance frequency is 2420Hz. With a 600μm diameter ball lens weighing 320μg mounted to the actuation structure, the resonance frequency is reduced to 752Hz without significantly impacting the static out-of-plane deflection behavior. In comparison to other micro-lens actuator, this structure demonstrates large deflection response and a relatively large resonance frequency.","PeriodicalId":6465,"journal":{"name":"2015 Transducers - 2015 18th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73700689","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}

In comparison to the state of the art, this technique adopts an approximation-free algorithm and thus more accurately captures the complex nonlinear dynamics that often evades the description by Duffing equation. For the first time, the nonlinearity of LN-based laterally vibrating resonators is theoretically investigated and experimentally validated. The admittance response of both S0 and SH0 mode devices was simulated and measured in this work by forward and backward sweeping the excitation frequency at different power levels. Excellent agreement between simulations and measurements has been achieved.","PeriodicalId":6465,"journal":{"name":"2015 Transducers - 2015 18th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75655784","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 nonlinearity compensated gyroscope achieves high drive displacement (>10μm) while maintaining linear magnitude and phase frequency responses. The proposed tuning method also minimizes the amplitude-frequency (A-f) effects on the drive mode. Cancelling the drive nonlinearities leads to a better bias instability compared to the high displacement with nonlinear characteristics.","PeriodicalId":6465,"journal":{"name":"2015 Transducers - 2015 18th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73199274","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}
