Poly(urethane-urea) elastomers (PUUEs) have gained significant attention recently due to their growing demand in electronic skin, wearable devices, and aerospace applications. The practical implementation of these necessitates many exceptional properties ensure robust safe utilization. However, achieving an optimal balance between high mechanical strength, good self-healing at moderate temperatures, efficient flame retardancy for poly(urethane-urea) remains a formidable challenge. In this study, we incorporated metal coordination bonds flame-retarding phosphinate groups into the design simultaneously, resulting high-strength, self-healing, flame-retardant elastomer, termed PNPU-2%Zn. Additional supramolecular cross-links plasticizing effects phosphinate-endowed PUUEs with relatively remarkable tensile strength (20.9 MPa), elastic modulus (10.8 efficiency (above 97%). Besides, PNPU-2%Zn possessed self-extinguishing characteristics limiting oxygen index (LOI) 26.5%. Such elastomer superior can resist both fracture fire hazards, providing insights development high-performance components applications devices.

As flexible and wearable electronics play more important role in smart watches, glass virtual reality, the power supply to have been revealed attentions for long-term usage continuous healthy monitoring. To overcome challenge, self-powered BTO-PVDF/PDMS piezoelectric-triboelectric electric hybrid generators (BPP-HNG) are developed human gesture monitoring machine interaction (HMI) application without external supply. BPP-HNG based on BTO-PVDF PDMS films prepared by sol-gel spin-coating method. When BTO content is 20 wt.%, exhibits better electrical performance with an output voltage of 20.51 V. A real-time system designed interaction, which able control motion robot finger through BPP-HNG. could monitor recognize various gestures real time, enabling synchronization between hand robot's hand. With convergence AI technology big data, HMI expected realize potential smarter intuitive interactions.

Abstract Transient electronics with degradability or dissolvability on demand possess remarkable characteristics for wearable, bioelectronic, and implanted electronic devices. While synthetic materials have made significant progress in stretchability, they suffer from intrinsic limitations, including low degradation rates, poor mechanical compliance, high production cost, which restrict the growth of transient Herein, a versatile fabrication strategy is presented that combine resilient biopolymer substrate (gelatin biogels) liquid metal (Galinstan). The circuits gelatin biogel‐based are mechanically durable, exhibiting good compliance irregular deformable surfaces, thus can withstand long‐term exposure to dynamic deformation (about 60 000 cycles at strain 50%). More importantly, biogels naturally derived endowed thermally reversible gelling, enables on‐demand rapid dissolution recycling materials. As proof‐of‐concept, circuit‐based capacitive sensors, be degraded within 20 s, fabricated monitoring finger touching, morse code generation, electrical touchpad. Such provides guideline designing combination gels metal, this approach anticipated find applications human–machine interfaces wearable
