“…Device engineering was again employed to produce a nanomesh OECT (NMOECT), a porous structure, which enables the device to be comfortably laminated on human skin and simultaneously achieve local amplification ( Figure ). [ 129 ] To facilitate the successful device fabrication, PEDOT:PSS had to be spray coated onto the porous nanomesh substrate, with the performance of the device controlled by varying the number of spray coating cycles. Upon increasing the number of cycles, PEDOT:PSS filled more pores of the nanomesh, resulting in a more evenly distributed PEDOT:PSS film and higher channel conductance.…”

Recent research demonstrates the viability of organic electrochemical transistors (OECTs) as an emergent technology for biosensor applications. Herein, a comprehensive summary is provided, highlighting the significant progress and most notable advances within the field of OECT‐based biosensors. The working principles of an OECT are detailed, with specific attention given to the current library of organic mixed ionic‐electronic conductor (OMIEC) channel materials utilized in OECT biosensors. The application of OECTs for metabolite, ion, neuromorphic, electrophysiological, and virus sensing as well as immunosensing is reported, detailing the breadth and scope of OECT‐based biosensors. Furthermore, an outlook and perspective on synthetic molecular design of future channel materials, specifically designed for OECT biosensors, is provided. The development of optimized channel materials, creative device architectures, and operational nuances will set the stage for OECT‐based biosensors to thrive and accelerate their clinical prevalence in the near future.

“…Alternatively, the ultrathin frame electrodes are emerging candidates for conformal attachment on complex curvilinear surfaces thanks to lower adhesion energy and less stress than that of sheet electrodes with corresponding areas, as shown in Figure 2B 23 . The nanoscale framework structures, for example, nanomesh electrodes developed by Someya group also showcased the excellent conformability and data acquisition ability with high fidelity 30 . Neither the ultrathin sheets nor frameworks barely support themselves, making them difficult to transfer even with the aid of an extra support base.…”

On‐skin digitalization, streamlining the concept of the “human to device to cyberspace” platform, has attracted great attention due to its vital function in remote medicine and human–cyber interfaces. Beyond traditional rigid electrodes, soft electrodes with conformal and comfortable interfaces are essential for long‐term and high‐fidelity signal acquisition. In addition, the on‐skin data processing systems will get rid of complex cables toward a vision of fascinating form, being lightweight, skin‐friendly and even imperceptible. Although numerous soft materials and devices with mechanical tolerance have been developed, the study of conformal electrodes and on‐skin digital integrated systems are still in infancy. Here, the requirements and designs of conformal electrodes, the emerging opportunities and challenges from multichannel/multifunctional sensors to a whole new on‐skin sensing platform are highlighted.

E-textiles is a new hybrid field developed with the help of the integration of electronic components into our daily usage of textile products. These wearable e-textiles provide user-defined applications as well as normal textile clothing. The medical field is one of the major leading areas where these new hybrid products are being implemented, and relatively mature products can be observed in the laboratory as well as in commercial markets. These products are developed for continuous patient monitoring in large-scale hospital centers as well as for customized patient requirements. Meanwhile, these products are also being used for complex medical treatments and the replacement of conventional methods. This review manuscript contains a basic overview of e-textile systems, their components, applications, and usages in the field of medical innovations. E-textile systems, integrated into customized products for medical needs, are discussed with their proposed properties and limitations. Finally, some recommendations to enhance the e-textile system’s integration into the medical field are argued.
