Bioinspired Keratin-Based Eutectic Hydrogels for Intelligent Health Monitoring and Photothermal Therapy

), excellent low-temperature tolerance, and autonomous self-healing properties. The fabricated sensor exhibited a wide sensing range (2%-1000%) and can effectively monitor motion signals from various human joints. Furthermore, by integrating the sensor with deep learning algorithms, real-time monitoring of wrist soreness associated with wrist conditions and on-demand photothermal therapy were achieved, establishing a closed-loop monitoring-therapeutic platform. This work demonstrates that the PDA@Ag/PAA/PSBMA/FK eutectic hydrogel holds great promise for applications in wearable medical systems, auxiliary rehabilitation assessments, and therapeutic interventions.
