| Abstract Scope |
Hydrogel-based wearable devices have recently gained considerable interest due to their promising applications in real-time health monitoring and motion detection. However, achieving integrated high-stretchability, self-adhesiveness, and long-term water-retaining property simultaneously in hydrogel systems remains a big challenge, which limits their applications in wearable electronics. In this talk, I present multifunctional hydrogel materials designed for wearable strain sensors that can be manufactured by digital light processing technology. By tailoring the composition of chemically cross-linked networks, physically cross-linked networks, and surface microstructures, the 3D printed hydrogel exhibits promising superior and adjustable mechanical properties, tunable adhesion and good water-retaining property simultaneously. Through adding conductive ions, high ionic conductivity can also be achieved. Based on these integrated multifunctionalities, the 3D printed hydrogel device is suitable for wearable sensing applications. This work provides a prospect for 3D printable hydrogel devices with broad applications in wearable electronics and next-generation human-machine interfaces. |
