However, the physical properties of the films created by many state-of-the-art printing methods become highly dependent on printing parameters, resulting in varying thermal properties often differing significantly from their bulk ink components. To understand the influence of the printing process, we build upon our previous work, where a noncontact optical technique, known as modulated photothermal radiometry (MPTR), was used to measure the thermal conductivity of aerosol-jet-printed thin films. In this work, we use the method to study the thermal properties of extrusion-printed silver on glass and alumina substrates. A noise-resistant data analysis fitting technique is applied using a 2-D heat transfer model. The thermal conductivity measurement is validated using the Weidemann-Franz (WF) relationship from measured electrical conductivity values.","PeriodicalId":100623,"journal":{"name":"IEEE Journal on Flexible Electronics","volume":"4 3","pages":"126-136"},"PeriodicalIF":0.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073186","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}

Although strategies to improve performance have been reported, challenges exist in the smart performance of the electrodes in devices with real-time feedback and integration with advanced techniques such as the Internet of Things (IoT). This work demonstrates an approach to achieve smart performance using flexible conducting electrodes based on graphene nanoplatelets (GNPs)/poly(3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) nanocomposite by the incorporation of machine learning methods. Applications of the electrodes as smart electrothermal heater and touch panel have been demonstrated with intelligent performance. The integration of machine learning methods ensures smart functioning and helps to achieve better functionalities in both applications. This work paves the way for significant advancements in flexible electronics and touchscreen technology with the assistance of machine learning strategies.","PeriodicalId":100623,"journal":{"name":"IEEE Journal on Flexible Electronics","volume":"4 3","pages":"117-125"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10945855","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
