While driven shields are state of the art for traditional printed sensors, they are still uncommon in contemporary textile user interfaces (UIs). Using an enameled copper wire as a bobbin thread in computerized machine embroidery, both sensor and shield electrodes are applied in a single sequence, eliminating manual intermediate or finishing steps and harnessing the design flexibility provided by the embroidery technique. Preliminary finite element analysis indicates significant improvements gained by employing driven shields, in terms of sensing range as well as signal quality, when the sensor is close to other conductors, e.g., when worn on the user’s body. By varying the shield electrode’s pattern properties, such as pattern type, area, and density, we investigate their effects on the resulting SNR, based on characterizations within controlled laboratory experiments. A major finding of our work is that the impact of density seems minor, while adjustments of the pattern layout seem to adequately compensate for a lower stitch density, with a grid layout yielding the best results.","PeriodicalId":100623,"journal":{"name":"IEEE Journal on Flexible Electronics","volume":"4 4","pages":"154-161"},"PeriodicalIF":0.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11007092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144323211","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}

A rapidly growing section of the semiconductor industry is flexible electronics which largely relies on the development of thin film transistors (TFTs), light-emitting diodes, solar cells, etc. on plastic substrates. With the deposition of these thin film being additive, the largest volume and weight percentage of the device is the substrate itself. Therefore, a substrate based on nonbiodegradable long-chain polymers is not a tenable choice with regard to sustainability. In this work, we demonstrate the development of TFT circuits on cellulose acetate substrates with the degree of substitution of the acetyl group on cellulose being 2.4. The key novelties of this work are the development of TFTs with 40% yield and the demonstration of small signal amplifiers on flexible sheets of cellulose acetate without the use of a planarization layer. The absence of a planarization layer, which is typically nonbiodegradable, removes the significant pollutant thereby making the eventual device largely biodegradable. It is shown that the TFTs obtained with and without the basement layer are not too different in performance. While the acetyl group on cellulose is understood to slow down the degradation, our demonstrations corroborate with other studies and demonstrate its degradation in soil.","PeriodicalId":100623,"journal":{"name":"IEEE Journal on Flexible Electronics","volume":"4 5","pages":"218-224"},"PeriodicalIF":0.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598101","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 the hybrid integration or sea-of-rigids, approach, conventional microchips are mounted onto (generally) plastic substrates such as polyethylene naphthalate (PEN), with (typically) printed silver tracks for interconnections between components. An ongoing research direction is to replace plastic substrates with biodegradable substrates and to replace silver tracks with nonheavy metal-based tracks. While the substrates and tracks form only part of an overall system, replacing them is a step toward increased sustainability and helps to meet net-zero goals for printed electronic systems. Previously, several papers have investigated printed carbon tracks for low-frequency analog sensing applications. This article explores the feasibility of using printed carbon tracks on biodegradable substrates for high-frequency applications such as digital signaling over a serial-peripheral interface (SPI). We investigate the printability, thermal stability, and electrical conductivity of carbon ink screen-printed onto six commercially available sustainable and flexible substrates. Our results demonstrate that multilayer screen printing substantially reduced the electrical resistance of carbon tracks, enabling SPI communication at frequencies up to 16 MHz with three layers of carbon ink. A Natureflex substrate provided the best balance of printability, thermal stability, and electrical performance. Substrates such as greaseproof paper and ClearFilm PU showed potential for flexible electronics, but require further optimization. This study provides valuable insights into selecting and optimizing biodegradable substrates for high-frequency digital systems, supporting the move toward more sustainable printed electronics.","PeriodicalId":100623,"journal":{"name":"IEEE Journal on Flexible Electronics","volume":"4 5","pages":"209-217"},"PeriodicalIF":0.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597725","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}
