Abstract

A bilayer material comprising catalyst-bearing microstructures embedded in a responsive gel and actuated into and out of a reactant-containing ‘nutrient’ layer continuously interconverts chemical, thermal and mechanical energy and thereby shows autonomous, self-sustained homeostatic behaviour, which regulates the temperature of the system in a narrow range.
