Ultrastrong, flexible thermogalvanic armor with a Carnot-relative efficiency over 8
2024
Overview
Body heat, a clean and ubiquitous energy source, is promising as a renewable resource to supply wearable electronics. Emerging tough thermogalvanic device could be a sustainable platform to convert body heat energy into electricity for powering wearable electronics if its Carnot-relative efficiency (
η
r
) reaches ~5%. However, maximizing both the
η
r
and mechanical strength of the device are mutually exclusive. Here, we develop a rational strategy to construct a flexible thermogalvanic armor (FTGA) with a
η
r
over 8% near room temperature, yet preserving mechanical robustness. The key to our design lies in simultaneously realizing the thermosensitive-crystallization and salting-out effect in the elaborately designed ion-transport highway to boost
η
r
and improve mechanical strength. The FTGA achieves an ultrahigh
η
r
of 8.53%, coupling with impressive mechanical toughness of 70.65 MJ m
−3
and substantial elongation (~900%) together. Our strategy holds sustainable potential for harvesting body heat and powering wearable electronics without recharging.
Flexible thermogalvanic device provides a sustainable platform for body heat harvesting, but its performance is limited by low energy conversion efficiency and poor mechanical strength. The authors report a flexible thermogalvanic armor with a Carnot-relative efficiency of 8.53% and strong mechanical toughness.
