Such high performance is achieved by arraying resonators designed with pronounced 3rd order shear horizontal (SH0) mode resonances. The 3rd order SH0 mode was selected to attain a 3× higher resonant frequency, and subsequently enable a filter center frequency beyond 1 GHz without resorting to costly fine-resolution lithography. To suppress the unwanted modes while maintaining a large electromechanical coupling (kt2), and a large fractional bandwidth, the ratio of the electrode pitch (Wp) to the total width of the resonator (W) has been optimized using finite element analyses.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"323 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115909263","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 viscometer can be exploited to measure viscosity of either Newtonian or non-Newtonian power-law fluid under various temperatures. The developed sensor-integrated microfluidic viscometer is made of polydimethylsiloxane (PDMS) with transparent electrofluidic circuit makes it feasible to real-time monitor samples under tests.

Under a low dc power consumption of the device with only 1.75 mW, the motional transconductance (gm) of the proposed TPR reaches record-high values both in vacuum (118.4 μA/V) and air (16.96 μA/V) among all reported CMOS-MEMS TPRs [1] and even on par with single crystal silicon (SCS) TPRs [2]. The unique design of a butterfly-shaped TPR with its low thermal capacitance (Cth) actuator beams is the key to improve the transduction efficiency and sensor sensitivity. The mass resolution of the proposed thermal-piezoresistive oscillator (TPO) attains 29.8 fg, which is extracted from the measured Allan deviation of 89 ppb. To verify the mass sensing capability, a pico-liter ink jet printing setup was used to demonstrate the real time response and frequency shifts corresponding to a number of droplets printed onto the proof-masses of the TPO with a high sensitivity of 1.946 Hz/pg, well suited for future aerosol detection.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127816885","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}
