We conduct theoretical, numerical and experimental study on the residual stress effect on the frequency responses of two types of polysilicon micro circular resonators: clamped and residual stress (RS) free design which can release the process-induced stress and is of easy fabrication. The measured natural frequency of the fabricated device is 39.8 kHz, in good agreement with both theoretical and FEM simulation results. We also determined the natural frequencies of these two designs as a function of residual stress. Under the same experimental RS condition of 50 MPa, the normalized changes of natural frequencies of these two designs are 159.7% versus 0.8%, respectively.","PeriodicalId":150449,"journal":{"name":"2016 IEEE 11th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129715827","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}

So far, we have developed a capacitive type tactile sensor network system for implementing a large number of sensors with MEMS-CMOS integration technologies [1-3, 9]. Considering practical use for the robot, multiple kind sensors in addition to numerous sensor distributions are necessary in terms of accurate object recognition and wide coverage of sensor requirements such as high-sensitivity, large dynamic range, high-reliability and low-cost. Thus, we proposed a sensor platform with dedicated CMOS-LSIs [6], which can utilize three types of sensors: on-chip temperature, off-chip capacitive and resistive tactile sensors. The CMOS-LSI is well designed for integration with MEMS. This paper describes the first implementation results of the multiple kind sensors with the CMOS-LSIs. We successfully constructed the multi sensor system, which has the temperature sensor, capacitive and resistive type force sensors.","PeriodicalId":150449,"journal":{"name":"2016 IEEE 11th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121629855","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 nano-gap electrode increases sensitivity of near-surface electrochemical conductances. To examine the proposed sensing characteristics of the nano-gap electrode, different conductive linkers (CB2C and PABA were immobilized to form a conductive layer on the nano-gap surface between the electrodes. The conductance increment of CB2C and PABA linker was about 56% and 396% respectively. This conductance improvement provides nano-gap electrodes ability for cTnT detection, also, the dynamic detection range of CB2C and PABA is from 1ng/ml to 100ng/ml and from 10pg/ml to 100ng/ml respectively.

In this system, a droplet (1.25μL) consisting of a mixture of functionalized microbeads and analyte is flowed through a 0.51mm internal diameter silicone tube. Hydrodynamic forces alone produce a very efficient mixing of the beads within the droplet. We tested the agglutination at different speeds and show a robust response at the higher range of speeds (150 - 200μL/min), while also reaching a completion in the agglutination process. At these velocities, a length of 180cm is shown to be sufficient to confidently measure the agglutination assay, which takes between 2.5 - 3 minutes. This high throughput quantification method has the potential of accelerating the measurements of various types of biomarkers, which can greatly benefit the fields of biology and medicine.","PeriodicalId":150449,"journal":{"name":"2016 IEEE 11th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"34 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125719133","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}

Highly sensitive piezoelectric micromachined ultrasonic transducer (pMUT) operated in air 高灵敏度压电微机械超声换能器(pMUT)在空气中工作

It overcomes the inherent shortcomings of conventional bulk ultrasonic transducers such as acoustic impedance mismatching. In addition, pMUT does not require the extremely large input voltage as capacitive micromachined ultrasonic transducer (cMUT), which is potential to be integrated into portable electronics. The lead zirconate titanate (PZT) based pMUT has the best performance. Leveraging on our newly developed pulse poling process, the morphotropic phase boundary composition PZT (MPB-PZT) thin film is of high piezoelectric constant (d31=105pm/V) and low dielectric loss (~0.06). Benefited from such high performance PZT thin film and optimized design, the fabricated pMUT (500×300μm) achieves a displacement sensitivity of 807nm/V at its resonant frequency (482kHz) without DC offset. Compared to previously reported PZT pMUTs, even the dimension is much smaller; the sensitivity is still superior to them. The in-air transmitting performance is evaluated as well. A single pMUT element is able to generate 63.7dB sound pressure level (SPL) at 10 mm in air with only 2V input. The low input voltage not only provides low power consumption, but also prevents the unwanted PZT repolarization. The proposed highly sensitive pMUT shows its promise for integration with portable electronics.","PeriodicalId":150449,"journal":{"name":"2016 IEEE 11th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133364038","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}
