Abstract The rapid development of wearable electronics has placed higher demands on the design strategies triboelectric materials. Aerogels have potential to become advanced materials, however, traditional often require complex processes and additional chemical cross‐linking agents improve stability gel structure, which limits its practical application. In this work, a scalable sustainable self‐assembly drive strategy is proposed for bio‐based aerogels with multi‐scale winding structures. Interestingly, autoacceleration effect, regarded as “unfavorable” during autocatalytic polymerization supramolecules, rationally exploited provide supramolecules within matrix an abundance multiple hydrogen bonds at same time their gelation occurs. Thanks this, aerogel film exhibits ultra‐high tensile strength (104 MPa) remains undeformed after resisting impact 8000 times own weight. Highly robust films are used build self‐powered sensors ultra‐fast response in environments (48 ms), while enabling real‐time interaction between wearer information network. idea “ turning detriment into asset ” work provides new material construction highly sensors.

Photoelectrochemical (PEC)-type photodetectors are gaining significant interest as neoteric self-powered devices, owing to their high spectral responsivity and quick photoresponse. However, the underlying leakage issue makes aqueous electrolyte contained inside PEC-type unsuitable for manufacturing flexible optoelectronics.
