Bioinspired electrically stable, optically tunable thermal management electronic skin via interfacial self-assembly
JOURNAL OF COLLOID AND INTERFACE SCIENCE(2024)
摘要
The skin is the largest organ in the human body and serves vital functions such as sensation, thermal management, and protection. While electronic skin (E -skin) has made significant progress in sensory functions, achieving adaptive thermal management akin to human skin has remained a challenge. Drawing inspiration from squid skin, we have developed a hybrid electronic-photonic skin (hEP-skin) using an elastomer semi-embedded with aligned silver nanowires through interfacial self-assembly. With mechanically adjustable optical properties, the hEP-skin demonstrates adaptive thermal management abilities, warming in the range of +3.5 degrees C for heat preservation and cooling in the range of - 4.2 degrees C for passive cooling. Furthermore, it exhibits an ultra -stable high electrical conductivity of -4.5x104 S/cm, even under stretching, bending or torsional deformations over 10,000 cycles. As a proof of demonstration, the hEP-skin successfully integrates stretchable light-emitting electronic skin with adaptive thermal management photonic skin.
