Soft electronics with high adhesion strength, self-healability and stretchability had highly demanded for intimate adhesion interfaces on wet/dry biosurfaces and device protection. However, previous self-healable adhesives may have problems such as chemical contamination, skin damage, and manifesting self-healing ability in harsh environments. Here, we report the self-healable bioinspired adhesive patch with stretchable, reusable interface for biosignal monitoring even in harsh environment. The patch has efficient self-healing and mechanical property, respectively and it performed faster healing rate than that of human’s skin. Our patch also shows good normal adhesion in both dry and underwater conditions (max. 7.82 N/m2 in dry conditions, and max. 4.44 N/m2 in underwater conditions). Based on the robust adhesion property, we have successfully obtained reliable measurements of biosignals during body movement.
