The different stub types are combined with the inductive and capacitive elements of the particular oscillator and serve as the sensing elements in the respective setup. The input impedances of the stubs highly depend on the permittivity of the medium. Therefore, the oscillation frequencies correspond to the dielectric material under test (MUT). The sensors response to different dielectric properties has been investigated using different Methanol-Ethanol solutions The conducted experiments show that the proposed architectures indicate the MUTs permittivity with a maximum frequency shift of 4.3 % for a change in permittivity of 2.4. Each of three sensors has an chip-area of 0.6 mm2 and consumes less than 12 mW power. The proposed sensor is a potential component for future low-power front-ends to perform minimally invasive investigations of bio-materials.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120850270","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}

Its ability to resolve small permittivity differences with a high dynamic range was proved by analytical calculations and full-wave EM simulations and was finally validated with measurements. A sensitivity of τ = 2.5dB/%Δεr>eff was achieved for small permittivity differences. Thereby, a change of 100 % ethanol to 99 % ethanol mixed with 1 % DI water, results in a difference of ΔS21 = 5 dB. In order to further minimize the complexity e.g. for single use purposes, the influence of the absence of the termination resistors of the couplers was investigated.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131215056","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}

Gastric electrical stimulation (GES) to the stomach has been used to treat the symptoms of gastroparesis. It usually consists of a large stimulator implanted inside the abdominal cavity with electrodes attached to the stomach tissues. In this work, we have designed, developed and tested a wirelessly powered gastric stimulator based on a flexible substrate that can be rolled into a capsule for endoscopic delivery and implantation. The stimulator can be conformed to the stomach curvature and attached onto the tissues. Characterization of transmitter and receiver antennas to wirelessly power the implant devices was conducted with near-field inductive coupling.

In this regard, we have previously presented a novel Resistive Wireless Analog Passive Sensor (rWAPS), which is fully-passive, fast, low cost, and operates on the near field induction coupling method. Printed spiral coils (PSC) are one of the best solutions for near-field wireless communication for this fully-passive sensor. This paper describes a formal method to implement and optimize PSC coil pairs for such a system. Iterative process is required to reach optimal solutions of this complex multivariate optimization problem. After optimum design based on coil dimension, track size, and number of turns, a coil pair was fabricated on 2-layer PCB. The secondary coil size was restricted to a small footprint of 20mm, while the carrier frequency was selected as 13.56 MHz within ISM frequency band. Evaluation of the measurement from the prototypes and theoretically calculated results were found to be in agreement. This approach of PSC design optimization is practical for its application in our previously reported resistive transducer based wireless analog passive sensors (rWAPS) for body worn and wearable medical CPS.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126842511","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}
