This process is performed at ≥ 900°C, which limits the device fabrication to rigid, high-temperature resistant substrates such as silicon. We obtain carbon patterns on commercially available polyimide films by a controlled laser writing, which induces a pyrolysis-like effect and causes the partial conversion of the polyimide into an electrically conductive, high-surface area carbon material. These flexible carbon patterns are characterised using microscopic and spectroscopic techniques, and are used as electrodes for the electrodeposition of chitosan. Subsequently, urease enzyme is immobilised on the chitosan film, and this composite electrode assembly is used for pH-based urea detection. This lithography-free, low-cost, and rapid fabrication process is capable of polyimide surface patterning with any desired shape in the micro- to millimeter range. Electrodeposited chitosan films can be used for the immobilisation of a variety of enzymes and chemical moieties for biosensing applications.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"105 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75165985","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 bending parameters include bending angle, bending radius and bending cycle. While the bending angle does not affect the performance of the solid EC cells significantly, small bending radius increases the cell resistance from a delamination at the current collector/electrode interface. A large bending cycle causes a severe self-discharging by losing mechanical protection at the electrolyte/separator layer. The layer is pierced through, creating localized contacts between electrodes which lead to a high leakage current. The electrode/electrolyte interface remains relatively intact under various bending conditions. The investigation of these parameters together with cross-sectional analyses provide a systematic understanding of the failure mechanism of thin and flexible ECs under bending. Although the approach was demonstrated on a sandwiched solid EC cell with a commercial activated carbon and a neutral pH polymer electrolyte, it can be extended for quantified investigations of mechanical properties of general solid flexible electrochemical devices.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"1 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":"88846086","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}

To achieve infra-red (NIR) light detection, we have developed low band gap conjugated polymers as electron donor and intermixed with various electron acceptors to form bulk heterojunction morphology for photoactive layer. The developed NIR OPD sensor showed high EQE over 30 % at 1000 nm wavelength and photosensitivity. The flexible RED OLEDs with conjugated polymer emitters has been achieved maximum luminance > 10,000 cd/m2 at 9 V, with peak at 640 nm. PPG signals were successfully detected using the developed flexible PPG sensor and conventional driving circuit. Human studies were conducted to evaluate the flexible PPG sensor performance in practical applications. Subject drowsiness was estimated from heart rate variability, extracted from the PPG signals, using machine learning algorithms. The flexible PPG sensor achieved 79.2% accuracy and 72.1% area under receiver (AUC) to predict drowsiness (60 sec window), which are meaningful results compared with conventional PPG sensors (83.3% accuracy and 69.0% AUC). Drowsiness estimation experiments using two PPG signals showed the flexible PPG sensor achieved similar or better performance to conventional PPG sensors.","PeriodicalId":6609,"journal":{"name":"2018 International Flexible Electronics Technology Conference (IFETC)","volume":"54 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85249641","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}
