The proposed technique reallocates the coefficients resulting from a wavelet transform to get a concentrated picture over the time-frequency plane, from which the instantaneous frequencies can be extracted. Through experiment and direct comparison with contact sensors, the instantaneous respiratory and heartbeat frequencies can be accurately obtained by the proposed method.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"4 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":"129448062","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 custom-made graphical user interface can display the slow waves in real-time and store them for off-line analysis. The user can turn on a switch on the back-end to activate electrical stimulation capability on the front-end. The electrical stimulation on the front-end is fixed at 4 mA with a pulse width of 300 ms. The front-end measures 13×44×4 mm3, allowing future implantation.

In this work, a portable frequency-modulated continuous-wave (FMCW) radar prototype for indoor human tracking is presented. The system provides absolute-range detection capabilities. Furthermore, it uses a novel approach - not requiring the sharing of the generation and acquisition clocks - to possess the highly-desired coherence feature, which enables the preservation of the phase history of targets. As a result, videos of inverse synthetic aperture radar (ISAR) images - i.e., videos of range-Doppler frames - can be reconstructed. Experimental results for a walking person in a highly-cluttered indoor environment confirm the suitability of the low-cost radar prototype for indoor healthcare applications.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"23 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":"123161119","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 sensitivity study has therefore been achieved for metal thicknesses comprised between 0.3 and 20 μm. After the validation of electromagnetic simulations with measurements of 10 μ m-diameter polystyrene bead, both capacitive and conductive contrasts have been defined for the different metal thickness of the sensor. The maximal sensitivity improvement is therefore achieved for a thickness value similar to the diameter of the particle or cell to measure. Capacitive and conductive contrasts are increased by a factor 2.4 and 1.75 respectively. The study leads consequently to an important design and fabrication rule of such a sensor.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"2 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":"117239879","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}

When using Doppler radars, this RBM suppression has been typically carried out through phase measurements obtained from two opposite sides of the human body. In this work, the employment of two frequency-modulated continuous-wave (FMCW) radars to deal with the RBM phenomenon is proposed. An advanced range-bin alignment technique is utilized to derive the range histories from the two transceivers and proceed with the RBM mitigation. Moreover, since this approach is only based on the signal amplitudes, the FMCW radar sensors do not need to be coherent. Simulated results are also reported to corroborate the effectiveness of the devised RBM suppression technique.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"50 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":"128235010","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}
