Abstract

Aggregation-induced emission (AIE) systems face challenges in low-visibility environments, particularly for monitoring applications at night, due to optical and electrical signal feedback limitations. To address this issue, we developed fluorescent ionogels (TPPE-IL) by incorporating TPPE into an ionic liquid matrix. This innovative combination enhances the performance of wearable electronic devices through improved ionic conductivity, softness, and transparency. TPPE-IL exhibits significantly higher fluorescence intensity than hydrogel systems, making it more effective for nighttime monitoring. It demonstrates exceptional fluorescence stability during continuous stretch-release cycles (1000 s) and robust adhesive properties. Additionally, it exhibits excellent environmental stability and dehydration resistance. The sensitivity of TPPE-IL as a sensing material is 1.85, making it suitable for high-performance deformation sensors. Notably, the strain sensor based on TPPE-IL enables real-time monitoring of human and giant salamander movements at night, providing high sensitivity and reliable signal response. This study highlights the potential of TPPE ionogels in wearable electronics and ecological monitoring, offering a significant reference for developing new fluorescent ionogels.

期刊介绍： Sensing and Bio-Sensing Research is an open access journal dedicated to the research, design, development, and application of bio-sensing and sensing technologies. The editors will accept research papers, reviews, field trials, and validation studies that are of significant relevance. These submissions should describe new concepts, enhance understanding of the field, or offer insights into the practical application, manufacturing, and commercialization of bio-sensing and sensing technologies. The journal covers a wide range of topics, including sensing principles and mechanisms, new materials development for transducers and recognition components, fabrication technology, and various types of sensors such as optical, electrochemical, mass-sensitive, gas, biosensors, and more. It also includes environmental, process control, and biomedical applications, signal processing, chemometrics, optoelectronic, mechanical, thermal, and magnetic sensors, as well as interface electronics. Additionally, it covers sensor systems and applications, µTAS (Micro Total Analysis Systems), development of solid-state devices for transducing physical signals, and analytical devices incorporating biological materials.
