Screen-printed silver coating of 25 μm thickness serves as the antenna metallization. Improved feed-design and systematic optimization of the antenna overcomes the intrinsic constrains of designing microstrip antennas on extremely thin substrate. Optimally designed feed excites a nearly square patch antenna with truncated corners to achieve good impedance and radiation characteristics. The proposed antenna exhibiting 48 MHz impedance bandwidth (896 MHz to 944 MHz) and a 16 MHz AR bandwidth (907–923 MHz), can serve as a potential candidate as a low cost UHF reader antenna for RFID applications.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"42 6 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81797211","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}

The performance of these solid flexible devices was systematically compared to commercial activated carbon (AC) and liquid electrolyte baseline. Solid-state devices especially chitosan AC enabled supercapacitors were shown to closely resemble the highly capacitive behavior and high rate performance of their liquid counterparts. This demonstrates that high surface area, intricately porous activated carbon networks can still be readily accessible to polymer electrolytes, which is important to the transition of supercapacitor devices from liquid to solid-state. These materials and systems represent simple, sustainable and cost-effective approaches for next-generation solid thin, flexible energy storage devices.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"23 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78183412","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 this work, the energy offset (EDA) of several donor-acceptor heterojunctions is determined by using the in-situ ultra-violet photoemission spectroscopy (UPS). It was found the substrate workfunction has negligible impact on the energy level alignment between the donor and the acceptor. The planar OPV cell is then fabricated to relate the VOC to the experimentally measured EDA. A surprising transition has been observed in the VOC-EDA plot. A simple mathematical model is developed, based on the exciton dissociation process inside the OPV cell. The model successfully explains the observed transition.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"23 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84460736","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}

Cicoira","doi":"10.29363/NANOGE.AOHM.2019.042","DOIUrl":"https://doi.org/10.29363/NANOGE.AOHM.2019.042","url":null,"abstract":"Organic electronics, based on semiconducting and conducting polymers, have been extensively investigated in the past two decades and have found commercial applications in lighting panels, smartphone and TV screens using OLEDs (organic light emitting diodes) technology. Many other applications are foreseen to reach the commercial maturity in future in areas such as transistors, sensors and photovoltaics.Organic electronic devices, apart from consumer applications, are paving the path for key applications at the interface between electronics and biology, such as in polymer electrodes for recording and stimulating neural activity in neurological diseases. In such applications, organic polymers are very attractive candidates due to their distinct property of mixed conduction: the ability to transport both electron/holes and ionic species. Additionally, conducting polymers offer the possibility to tune their surface properties (e.g., wettability or chemical reactivity) by changing their oxidation state, thus promoting or hindering the adhesion of biomolecules. This feature can be particularly useful for enhancing the biocompatibility of implantable electrodes.My talk will deal with processing and characterization of conducting polymer films and devices for flexible, stretchable and healable electronics for energy and medicine application [1–7]. I will particularly focus on micro-patterning of conducting polymer films for flexible and stretchable devices and on healing of conducting polymer films.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"1 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2018-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87164894","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}
