AI Technical Summary
Existing electrode-skin interface materials suffer from problems such as decreased adhesion, unstable contact, signal drift, and motion artifacts during long-term use, making it difficult to meet the requirements for long-term continuous monitoring and repeated use.
A composite hydrogel with reversible hydrogen bond interactions is formed by gelatin and polyacrylic acid network. Electrode-skin interface material is prepared by free radical polymerization reaction. Combined with sheet structure and flexible electrode substrate, an electrode assembly is formed to adapt to the dynamic deformation of human skin.
It improves the contact stability of the electrode-skin interface and the stability of signal acquisition, reduces interface slippage and contact impedance fluctuations caused by skin movement, and enhances the adhesion and biocompatibility of the material.
