Abstract: A dual-mode heating and cooling system includes a dual-mode heating and cooling device including a cooling part and a heating part that are configured to be selectively exposed to sunlight in a cooling mode and a heating mode, respectively, with the cooling part configured to provide radiative cooling to a structure, and with the heating part configured to provide solar heating to the structure. The device may include a film with the cooling part and the heating part side-by-side on the film.

Abstract: The present disclosure describes a multimodal adaptive textile with moisture-responsive flaps composed of a nylon/metal heterostructure, which can simultaneously regulate convection, sweat evaporation, and mid-infrared emission to accomplish heat transfer tuning in response to human perspiration vapor. A metal layer contributes to low-emissivity radiative heating and enhances the bimorph actuation performance. The multimodal adaptive mechanism expands the thermal comfort zone compared to traditional static textiles and single-modal adaptive textiles without any electricity or energy input.
