摘 要：Flexible electronics are playing an increasingly important role in human health monitoring and healthcare *** adhesion on human tissue would be ideal for reducing interface resistance and motion artifacts,but arising problems such as skin irritation,rubefaction,and pain upon device removal have hampered their ***,inspired by the temperature reversibility of hydrogen bonding,a skin-friendly conductive hydrogel with multiple-hydrogen bonds was designed by using biocompatible poly(vinyl alcohol)(PVA),phytic acid(PA),and gelatin(Gel).The obtained PVA/PA/Gel(PPG)hydrogel with temperature-triggered tunable mechanic could reliably adhere to skin and detect electrophysiological signals under a hot compress while be readily removed under a cool ***,the additional advantages of transparency,breathability,and antimicrobial activity of the PPG hydrogel ensure its long-time wearable value on the *** is both environmentally friendly and cost saving for the waste PPG hydrogel during production can be recycled based on their reversible physical *** PPG hydrogel sensor is expected to have good application prospects to record electrophysiological signals in human health monitoring.
