摘要：

In the field of skin-attachable electronics, debonding-on-demand (DoD) adhesives triggered by mild, efficient, and accessible stimuli can facilitate repeated usage with negligible damage to the skin. Here, a simple and versatile method has been developed to fabricate biocompatible bonding/debonding bistable adhesive polymers (BAPs) with skin temperature-triggered conformal adhesion and roomtemperature-triggered easy detaching. Its potential application in a mechanosensitive communication system is also explored. The BAPs are designed by incorporating stearyl acrylate (SA) and tetradecyl acrylate (TA) into a chemically crosslinked elastomer, where a semicrystalline-to-amorphous transition between 26 degrees C and 32 degrees C results in high adhesive flowability and large energy dissipation. An optically transparent and mechanically compliant debonding-on-demand triboelectric nanogenerator (DoD-TENG) is fabricated using the BAP as the DoD substrate, a polydimethylsiloxane elastomer as the electrification layer, and an ion-conductive elastomer as the electrode. Furthermore, the DoD-TENG can serve as a human-machine interface for a self-powered drone navigation system.
