To clearly distinguish respiration rates from moving subjects, the SSM, originally developed for radar target identification and sensor fusion, is applied in a sliding short-time window for enhanced resolution in vital sign detection. This application of SSM to sliding short-time data, termed hereafter as short-time SSM (STSSM), is validated with a full-wave electromagnetic simulation of a walking subject using the Boulic model to represent the kinematics. The scattering model is utilized to calibrate the state space system parameters before it is applied to experimental UWB radar data. The cross correlation and weight functions are utilized to cancel the random motions attributed by walking from a human subject, prior to the application of STSSM to UWB signal. The results show that STSSM can be successfully utilized to accurately measure vital signs in real experimental data, thus demonstrating the capability to positively identify respiration rates even in a low signal-to-noise ratio environment.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121412470","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}

Dry electrodes for impedimetric sensing of physiological parameters (such as ECG, EEG, and GSR) promise the ability for long duration monitoring. We have previously demonstrated a novel nanotechnology based dry electrode configuration fabricated with patterned vertically-aligned carbon nanotube (pvCNT) for neuro-physiological impedimetric measurements. However, the fabricated sensors were mechanically weakly adhered to the substrate. This paper describes a coating mechanism of pvCNT with a thin layer of conductive polymer, Polypyrrole (PPy), to increase mechanical stability, while preserving superior impedance properties of pvCNT. The electrodes were fabricated on circular stainless-steel (SS) foil substrate (φ = 10 mm, and thickness = 2 mils). Electrically conductive multi-walled CNT were grown in pattered pillar formation with a square base of 100 μm each side, and an inter-pillar spacing of 200 μm. The heights of the pillars were between 1 to 1.5 mm. The coating procedure involved applying 10 μL of PPy after preparing the pvCNT with 70% ethyl alcohol solution, and flash drying at 300°C. A comparative test with commercial ECG electrodes and non-coated version show that coated pvCNT has lower electrical impedance compared to commercial electrode whereas higher impedance compared to non-coated version. The signal capture were comparable for all electrodes in vitro. The peel test reveal much stronger mechanical adhesion of the pvCNT with the SS substrate when coated with PPy. The results demonstrate the feasibility of coating pvCNT dry electrodes with PPy for robustness.","PeriodicalId":154090,"journal":{"name":"2016 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"1 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":"129731922","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}
