| Outline of Annual Research Achievements |
The collaborative research has led to the development of a novel approach to creating interconnected organic-based nanomesh for electrodes used in skin electrical properties monitoring and connected to textiles. The fabrication method involves the combination of different nanofibers through multilayer electrospinning and the tuning of a part of the deposition to form a thickness gradient, enhancing stability and functionality. The resulting interconnected electrode removes the necessity for separate components, producing a seamless interface. Furthermore, conductive yarn is integrated into the electrode, replacing conventional rigid metallic wiring. In proof-of-concept phase, various tests were conducted to evaluate transparency, mechanical properties, and skin impedance, comparing the gradient nanomesh to conventional and previous electrode types. The results suggest that the gradient nanomesh performs similarly to conventional electrodes and demonstrates advantages in skin impedance measurements, paving the way for potential applications in next-generation smart apparel design. Additionally, the approach allows direct and improved connection of skin-conformable electrodes with textiles, demonstrating potential versatility and advancement in wearable technology.
