The active layer was manufactured by means of a spray-deposited semiconducting single-walled carbon nanotube (SWCNT) thin film. The device was functionalized with an ion-selective membrane, based on the nonactin ionophore. The characterization was carried out by means of transfer and output curves, to test the response of the devices towards different concentrations of ammonium. The calibration curve of the fabricated sensors showed a linear detection range for ammonium from 0.01 to 10 mM, which covers the entire range of physiological concentrations of interest, with average sensitivities of 0.346 µA/decade and 94.35% coefficient of determination.","PeriodicalId":289035,"journal":{"name":"2022 IEEE International Flexible Electronics Technology Conference (IFETC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125561323","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}

Generally, multiple functinalities and low power consumption are important performance parameters to be considered [1]. Currently, most haptic feedback devices utilize piezoresistive materials to detect force signals [2], [3], which in nature have drawbacks in spatial resolution and sensitivity. Piezoelectric sensors are also optional, however, traditional piezoelectric sensors cannot detect static force signals, both of which face challenges in forming a pixelated array which can visualize the haptic gestures. In this work, a flexible tactile sensor formed by a 10×10 pixelated piezoelectric sensor array and its sensor interface circuit is proposed to achieve the haptic visualization of dynamic and static force stimuli.","PeriodicalId":289035,"journal":{"name":"2022 IEEE International Flexible Electronics Technology Conference (IFETC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121396133","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}

This paper presents a high-density 4T1C CiM design based on stacked channel-all-around (CAA) In–Ga–Zn-O (IGZO) TFTs. The 4T1C CiM cell exhibits an 8F2 feature size plus further stacking possibility. An interleaved timing control is adopted to reduce the interference of adjacent lines in the compact layout. With the back-end-of-line (BEOL) integration capability, the proposed CiM structure can be integrated vertically above CMOS peripherals to build a high-throughput area-efficient 3D CiM architecture, showing high storage density of 7.40 Mb/mm2/layer and high computing density of 92.6 TOPS/mm2 for CiM array only.","PeriodicalId":289035,"journal":{"name":"2022 IEEE International Flexible Electronics Technology Conference (IFETC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130884078","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}
