The effects of adding natural orange peel fiber and MOF on the mechanical and electrical conductivity of PVA hydrogels were investigated. The results showed that the rigidity of the composite hydrogel after adding natural orange peel fiber without cross-linking agent increased with the addition of natural orange peel fiber, and the internal pore structure of MOF-PVA composite hydrogel was more abundant with the increase of natural orange peel fiber, forming a honeycomb-like porous material. Therefore, the composite addition of natural orange peel fibers can effectively improve the mechanical properties and pore structure of PVA gels to achieve the enhancement effect.","PeriodicalId":289035,"journal":{"name":"2022 IEEE International Flexible Electronics Technology Conference (IFETC)","volume":"70 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":"129140233","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}

First, to employ high In content thin film to boost the mobility. Second, to take the advantage of atomically thin film by atomic layer deposition to suppress the crystallization and to form the amorphous phase. Third, to use the quantum confinement effect in nanoscale thickness to modulate the carrier density. As in conventional sputtering deposition approach without the capability of atomically thickness control, high In content films usually lead to high carrier density and crystallization so that carrier concentration is usually too high for practical device. Thus, ALD is an ideal process to realize ultra-thin channel for high mobility oxide semiconductors.","PeriodicalId":289035,"journal":{"name":"2022 IEEE International Flexible Electronics Technology Conference (IFETC)","volume":"11 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":"115302033","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}

However, current flexible tactile electronic skin sensors suffer insufficient flexibility and sensitivity, as well as high-cost and low-efficiency in fabrication and susceptible to contaminant in sensing performances. Here, a highly sensitive all-flexible tactile sensor (AFTS) is presented with capacitive sensing that combines double-side micropyramids dielectric layer and liquid metal (LM) electrode. The design and fabrication of LM-based AFTS are based on supermetalphobicity induced by femtosecond laser. The supermetalphobic micropyramids lead to high sensitivity up to 2.78 kPa-1, ultra-low limit of detection of ~ 3 Pa, fast response time of 80 ms, and excellent durability of cyclic load over 10000 times. The used femtosecond laser enables programmable, high-efficiency, low-cost, and large-scale fabrication of supermetalphobic double-side micropyramids, which is difficult to implement using conventional techniques. Furthermore, the outer substrates are treated by femtosecond laser, endowing the AFTS with excellent antifouling performance, and stable sensing signals in the highly humid environment. Successful monitoring of human physiological and motion signals demonstrates the potential of our developed AFTS for wearable biomonitoring applications.","PeriodicalId":289035,"journal":{"name":"2022 IEEE International Flexible Electronics Technology Conference (IFETC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114427970","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}

At the same time, these clusters are exposed to an increasing number of attacks coming from public networks. Therefore, mechanisms for efficiently and flexibly managing security have now become an essential requirement for clusters. However, despite the growing importance of cluster security, this field has been only minimally addressed by contemporary cluster administration techniques. This paper presents a high-level view of existing security challenges related to clusters and proposes a structured approach for handling security in clustered servers. The goal of this paper is to identify various necessarily-distributed security services and their related characteristics as a means of enhancing cluster security.","PeriodicalId":289035,"journal":{"name":"2022 IEEE International Flexible Electronics Technology Conference (IFETC)","volume":"367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123405501","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}
