This paper proposes and demonstrates an experimental working bench-top model for the first time of a wireless powering scheme for bio-medical implants through a 2-contact resonant capacitive link where data has been transmitted simultaneously in a hybrid amplitude-frequency shift keying (ASK-FSK) technique over the same channel. This technique is well suited for a high-density micro-stimulation implants and the data telemetry rate is independent of the power carrier frequency. A proof-of-concept table-top setup using 20 mm × 20 mm flexible and conformable capacitive patches with a beef slice of 3 mm thickness demonstrates this idea and helps us carry out preliminary experiments. Experimental results show that for an air-kapton gap between the capacitive patches, the power delivered to the load (PDL) is up to 90 mW with data transfer rate of 170 kbps and power transfer efficiency (PTE) of 70%, whereas for a 3 mm thick beef tissue sample separation with the same setup, the observed PDL was 12 mW with a PTE of 36%.","PeriodicalId":259162,"journal":{"name":"2018 IEEE Biomedical Circuits and Systems Conference (BioCAS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123316665","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 general, psychophysical tests based on the administration of a prototypical bitter compound, 6-n-propyltiouracil (PROP), and on a subjective scoring, are exploited. Since the PROP tasting ability is correlated to food preference and also to several clinical and health-related conditions, the development of low-cost hardware/software tools for accurate testing (e.g., in pharmacies) is an important goal. Previous works revealed the possibility to perform an electrophysiological measurement on the tongue able to provide objectiveness and repeatability in this kind of study. The technique, called Electrotastegram (ETG), relies on a custom thin-film electrode and an off-the-shelf electrophysiological recording system. In this work, we present a prototypical low-cost pocket-sized wireless device for ETG, comparing the signal quality against a top-class electrophysiological recording system already used for the same measurements. A custom Matlab interface was developed to collect and process the signal. By acquiring the signals at the same time with both devices, it was possible to compare the quality in terms of noise, amplitude and waveform. The results reveal a substantial equivalence between the two devices, thus opening to the possibility of using the proposed system in real scenarios, possibly substituting the Matlab interface with a stand-alone software.","PeriodicalId":259162,"journal":{"name":"2018 IEEE Biomedical Circuits and Systems Conference (BioCAS)","volume":"288 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117285284","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}
