AI Technical Summary
Existing commercial silver chloride gel electrodes suffer from performance degradation due to gel dehydration and motion artifacts caused by sliding during long-term use. They also have high interfacial impedance, which affects the acquisition of electrophysiological signals.
Adhesive low-impedance skin electrodes were fabricated using MXene material. By preparing a patterned MXene film and an adhesive film stack, a self-adhesive skin electrode was formed by vacuum heating and curing, avoiding the use of gel. By combining polydimethylsiloxane and the surfactant Triton X-100, low impedance and good adhesion were achieved.
It achieves close contact between low-impedance skin electrodes and skin, obtains electrophysiological signals with high signal-to-noise ratio, avoids performance degradation caused by gel dehydration, is suitable for long-term use and is easy to mass-produce.
