High-performance compliant thermoelectric generators with magnetically self-assembled soft heat conductors for self-powered wearable electronics

This paper introduces compliant thermoelectric generators (TEGs) that achieve high thermoelectric performance and conformability. Silver-nanowire-based soft electrodes interconnect bismuth-telluride-based thermoelectric legs, enabling the TEGs to conform to curved surfaces. Magnetically self-assembled metal particles in elastomeric substrates create soft heat conductors, enhancing heat transfer and energy conversion efficiency. Automated additive manufacturing allows for the creation of customizable TEGs with hundreds of legs, demonstrated in a self-powered wearable warning system.
