An upper C-ring resonator induced with an underneath linear micro-strip is used to generate the complementary resonance. The induced electromagnetic resonance is sensitive to surrounding material properties including complex permittivity and thickness of materials. The insertion loss of the GHz signal increases with the increasing material permittivity nearby the CSRR. Therefore, this technique is good to measure the ionic strength of solutions without using physical electrodes to contact the solutions. Results show that the developed CSRR chip is capable of detecting NaCl solutions of the concentration ranging in 10−3∼5.0 M with a sensitivity of 1.5 dB/M at high concentration range. The CSRR chip is also capable of distinguishing solutions of same concentration but different ionic charges. The developed CSRR chip has shown its potentials for remote monitoring the solution properties.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124967603","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}

Robustness and flexibility are highly desirable in sensors besides efficiency and sensitivity. This work reports a novel biomimetic approach for hair cell based sensors for flow sensing applications. We mimic the sensory organ of cavefish using flexible sensing membrane and hydrogel encapsulated carbon nanotube bundle. Infusion of hydrogel into the nanotubes ensures enhanced transmission of flow stimulus. Air flow testing results demonstrate the ability of these sensors to detect steady state flows.

The thickness extensional mode resonant frequency, where ultrasonic generation efficiency become large, is inversely proportional to the thickness of films. Bulk ScAlN thick plates are attractive for the low frequency and high power ultrasonic applications such as actuators and medical ultrasonics because ScAlN possess lower mechanical and dielectric losses compared with well-used PZT. The thick ScAlN films, however, has not been reported. The electromechanical coupling coefficient kt2 was determined to be 19% using the thickness extensional mode at 81 MHz.

The experimental result suggested that there was the threshold value of the maximum landing force per weight for legs, which determined that a fruit fly lands with contacting with six legs or colliding bodily to the ground according to the landing velocity.
