主　　题：liquid metal polymer-gel recycling stretchable electronics water-degradation 

摘      要：The rapid development of stretchable electronics made by circuits,microchips,and encapsulation elastomers has caused the production of a large amount of electronic waste(e-waste).The degradation of elastomers can highly minimize the negative effects of ***,chemicals that included acid,alkali,and organics were repeatedly used during the recycling process,which were environmentally ***,a water-modulation-degradation-reconstruction(WDR)polyvinylpyrrolidone(PVP)-honey composite(PHC)polymer-gel was developed and could be regarded as encapsulation elastomers to realize a fully recyclable water-degradable stretchable(WS)electronics with *** stretchability of the PHC polymer-gel could be modulated by the change of its water *** Chip-integrated liquid metal(LM)circuits encapsulated with the modulated PHC encapsulation elastomer could withstand a strain value of~3000%.Moreover,we developed a WS biomedical sensor composed of PHC encapsulation elastomer,LM circuits,and microchips,which could be fully recycled by biodegrading it in water to reconstruct a new *** before,the reconstructed WS biomedical sensor could still simultaneously realize the combination of ultra-stretchability,recycling,self-healing,self-adhesive,and self-conformal *** results revealed that this study exercises a profound influence on the rational design of multi-functional WS electronics.
