Publication: Elastocaloric heat pump with specific cooling power of 20.9 W g⁻¹ exploiting snap-through instability and strain-induced crystallization

Conventional refrigeration relies on hazardous agents, contributing to global warming. Soft, cheap, biodegradable solid-state elastocaloric cooling based on natural rubber offers an environmentally friendly alternative. Here, we combine snap-through instability with strain-induced crystallization and achieve a sub-100 ms quasi-adiabatic cycling, which is 30 times faster than previous designs.
