The fabricated 4-terminal MEMS relay with the one-contact design demonstrated a contact resistance of 18 mΩ, which is two order-of-magnitude lower value than that of the conventional two-contact design. To the best of our knowledge, this result is the lowest value in the 4-terminal MEMS relay and comparable value with the state-of-the-art in 3-terminal MEMS relay [14]. In addition, the relay was operated up to 1.1 × 106 cycles at 1 V / 50 mA in an air and hot switching condition with negligible contact resistance variation. The lifetime is 10 times longer than that of the conventional 4-terminal MEMS relay.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124431992","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}

Different longitudinal dimensions of the cantilevers can be achieved and well controlled with a (111) wafer single-sided process. The remained smooth backside facilitates simple post-packaging without chip bonding. The results of the high shock test show the sensitivity of X-/Y-axis and Z-axis is 0.80–0.85 μV/g and 1.36 μV/g, respectively.

A phytoplankton and a zooplankton have been selected for the driving source because of its nature of phototaxis, which unites the swimming direction to a specific orientation of the mechanism. First, a reciprocating micro-float was driven by Artemia, which is a salt water zooplankotn, with a driving speed of 0.3mm/s. Next, a rotary micro-ratchet was also driven by Artemia larva, with a rotation speed of 0.35 rpm. Lastly, a micro-ratchet is driven by Volvox — a phytoplankton, and achieved a rotation speed of 3.5rpm. Those may provide a new micro-actuators driven by microorganisms, which may develop an alternative kinetic energy harvesting and environment monitoring technology.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125300691","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 sensing mechanism utilizes piezoelectric transduction where an AC signal is applied to a polyvinylidene fluoride (PVDF) thin film to generate pulses of ultrasound waves that travel upwards through the sensor components to the contact interface while a receiver PVDF thin film detects the reflected waves and produces a localized voltage output that is detected by the TFT (Thin-Film Transistor) array layer. The ability of the tactile sensor to detect contact forces can be attributed to the sensor surface having a thin compliant PDMS layer with a microstructure array. When the sensor contacts objects, the microstructures act as force concentrators, resulting in the localized deformation of the PDMS layer and an observed linear response to normal static forces in the range of 1 to 6 N. The TFT array output after signal processing produces a two-dimensional grayscale image that enables not only high-resolution imaging but also contact force information for improved robotic grasping performance.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125509978","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}
