“…The resulting woven FOECT system can effectively monitor dopamine, lactate, and glucose with low detection limits (1 nM), high sensitivity (46.8 ± 3.3 mV/dec for dopamine, 85.3 ± 6.1 mV/dec for lactate, and 235.5 ± 20.8 mV/dec for glucose), good selectivity, and consistent results in artificial sweat. This research presents a practical strategy for the large-scale and stable fabrication of FOECTs, thereby driving advances in personalized healthcare sweat sensors [94]. Textile organic electrochemical transistors (txOECTs) were introduced in the study by Copped et al They have been functionalized with ion-selective membranes.…”

Sweat is an accessible biofluid that provides useful physiological information about the body’s biomolecular state and systemic health. Wearable sensors possess various advantageous features, such as lightweight design, wireless connectivity, and compatibility with human skin, that make them suitable for continuous monitoring. Wearable electrochemical sweat sensors can diagnose diseases and monitor health conditions by detecting biomedical signal changes in sweat. This paper discusses the state-of-the-art research in the field of wearable sweat sensors and the materials used in their construction. It covers biomarkers present in sweat, sensing modalities, techniques for sweat collection, and ways to power these sensors. Innovative materials are categorized into three subcategories: sweat collection, sweat detection, and self-powering. These include substrates for sensor fabrication, analyte detection electrodes, absorbent patches, microfluidic devices, and self-powered devices. This paper concludes by forecasting future research trends and prospects in material-based wearable non-invasive sweat sensors.

“…[241] Qing et al designed an industrial-scale textile OECT system, that could monitor dopamine, lactate, and glucose with a low detecting limit (1 nm), high sensitivity, and good selectivity (Figure 5h). [242] However, it remains a technical challenge to develop highperformance and stable textile OECT sensors for everyday onskin applications. On the one hand, the liquid electrolyte in OECT easily suffers from leakage and volatilization, which will reduce OECT sensitivity for everyday usage.…”

Textiles with a freedom of form factor, unlimited scalability, and high programmability provide an ideal platform for constructing wearable optoelectronic systems. The emerging wearable technologies, like artificial intelligence and Internet of Things, have driven the development of textile optoelectronics from simple functional blocks to sophisticated logic systems, offering a seamless, breathable, and programmable on‐body platform to synergistically sense, analyze, store, and feedback information in response to complex commands. In the past few years, the creation of such smart textile optoelectronics‐based logic systems is boosted by nanomaterial science and manufacturing integration technologies and has revolutionized human–machine interaction paradigms in numerous emerging fields. Herein, in this review, the recent progress of smart textile optoelectronics for human‐interfaced logic systems is timely summarized. This review begins with a concise discussion about the wearability evaluation and integration consideration of textile optoelectronic devices. Then, important breakthroughs in human‐interfaced logic systems based on smart textile optoelectronics are demonstrated by highlighting their representative device, working principle, and application scenarios. Finally, the existing challenges and potential directions in the field of textile optoelectronics‐integrated logic systems are analyzed.
