Here, we report on phase transition induced optical transmittance characteristics variation of electrochromic VO2 thin film grown on GaN membrane for light modulation application. Insulator metal transition (IMT) phase of the VO2 thin film was triggered using an electric field applied on the interdigitated metal electrodes deposited on it. Voltage triggered phase transition resulted in ~45% change in resistance of the thin film and ~11% reduction in transmitted optical power for a 1550 nm laser. Moreover, near-infrared light modulation utilizing IMT properties of the VO2 thin film-based membrane was demonstrated by applying various voltages with pulse widths ranging from 2 ms to 300 µs,","PeriodicalId":6814,"journal":{"name":"2021 21st International Conference on Solid-State Sensors, Actuators and Microsystems (Transducers)","volume":"21 1","pages":"593-596"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74308620","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 device is a chromium/aluminum/chromium stacked structure with a spiral shape fabricated on a $5times 5text{cm}^{2}$ glass substrate through microelectronic technologies. Its geometry has been designed and optimized by COMSOL Multiphysics in terms of pitch and line width to achieve a uniform temperature distribution. Measurements performed with a thermo-camera show temperature variation below 1.5°C over 5cm2 area in excellent agreement with numerical modeling. To our knowledge, this is the largest area with such temperature uniformity achieved with a single heater in lab-on-chip systems. This opens the route for large-area thermal treatments as multiple-well DNA amplification or cell culture.","PeriodicalId":6814,"journal":{"name":"2021 21st International Conference on Solid-State Sensors, Actuators and Microsystems (Transducers)","volume":"33 1","pages":"639-642"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75509876","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 organohydrogel exhibits remarkable stretchability (break strain 672%), and high mechanical strength (up to more than 370 KPa). Besides, the PVA-CNF organohydrogels remained in their original condition without any damage on the surface after stretching 15 times. Basing on the crosslinked hydrogen bond, this PV A-CNF organohydrogel exhibits repairability and remoldability.

TMGs are an emerging technology for waste heat recovery. Here, TMG operation relies on the abrupt drop of magnetization at the Curie temperature of a magnetic shape memory (MSMA) film of Ni-Mn-Ga mounted at the front of a cantilever and on rapid heat transfer due to the film's large surface-to-volume ratio. Parallel designs are highly demanded to increase power output. When exposed to heat source temperatures Ts of 110-170 °C, resonant self-oscillation of each cantilever is excited in the range of 50-70 Hz resulting in a power output up to $30 text{mW}/text{cm}^{3}$ for each TMG. At low Ts, oscillations remain stable even for a small distance $D$ of 0.4 mm between cantilevers, while at $text{Ts} geq 150^{circ}mathrm{C}$, instabilities occur below $D=1$ mm affecting power output.","PeriodicalId":6814,"journal":{"name":"2021 21st International Conference on Solid-State Sensors, Actuators and Microsystems (Transducers)","volume":"39 1","pages":"463-466"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74060337","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}

With shielding, our flexible MEAs have better resistance to external disturbances while maintaining good conformability with high-quality signals. We have performed both simulation and in vitro experiments to evaluate the efficiency of two shielding designs, showing that bell-type devices have better performance.
