The sensor uses a differential p-ISFET architecture which substantially reduces non-ideal common mode effects which corrupt readout in ISFET based pH sensors and occupy only a small footprint. Additionally, the design offers the capability to correct for drift through control of the n-well voltage, which has not been demonstrated previously. We present results obtained from testing the sensor that is fabricated in the AMS 0.35μm process, including a demonstration of the drift correction. We demonstrate a differential sensitivity of 15 mV/pH over the entire pH range, with the ability to remove the already small drift of 0.1 mV/min using the bulk-source voltage adjustment.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"93 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74908089","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}

In this work, we present a biodegradable 3D printed ferroelectret using Fused Deposition Modeling (FDM). Even though the charging process of the ferroelectret is conducted at room temperature, the printed PLA exhibits good charge stability over 150 days at this temperature. A distinctive feature of the manufactured ferroelectret is that its mechanical properties mainly depend on its geometry, offering the possibility for it to be softer than the printed material itself. In fact, the investigated geometry in this paper exhibits a Young’s modulus of 0.5 kPa for stresses under 1 kPa. An excellent piezoelectric coefficient of 600 pC/N was recorded, which is comparable with the well known polypropylene ferroelectret. The presented ferroelectret is suitable for various mechanical sensor application.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"37 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77587740","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}

A unique feature of the design is an integrated circuit solution for the Fraction of Plateau Phase (FOPP) detection. The FOPP is the percentage of time when beta-cells, in the islets of Langerhans in the pancreas, show burst activity, which is directly proportional to the extracellular glucose concentration. The proposed integrated FOPP detector circuit adopting a differential envelope detector structure keeps the design overhead to a minimum and only FOPP relevant information is well reserved and processed, resulting in a highly reduced data volume. This allows us to further apply this solution to more advanced invitro and in-vivo beta-cell activity monitoring.

Higher relative humidity levels (from 0 to 90%) downshifted the S21 amplitude and increased the quality factor of the device.

Using a passive structure to transduce the quantity of interest into an acoustic or electromagnetic wave could offer an attractive solution for remote sensing, lifting the requirements of installing active materials, electronics, and power sources in remote, inaccessible, sensitive, or harsh environment locations. Here, we report a simple cavity and ball structure that transduces fluid flow through a pipe into an acoustic signal. A microphone on the outside wall of the pipe records the intensity and arrival rate of the sound pulses generated by collisions between the ball and the cavity walls. Using this approach external measurement of flow is demonstrated with adequate repeatability before any acoustic signal processing. This result is expected to open the way to the implementation of passive, remotely readable sensors for fluid flow and other fluid properties of interest.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"224 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85380382","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}
