Perspective on the Next Ten Years of Wearable Passive Radiative Thermoregulation

In the past ten years, wearable passive radiative thermal management has rapidly developed into a pivotal research topic in the human–building–energy nexus that protects personal health, promotes thermal comfort, and reduces CO 2 emissions associated with building heating and cooling. As the global temperature continues to rise, there will be additional challenges, opportunities, and transformative impacts on the next ten years of wearable passive radiative thermal management. This Perspective will discuss the historical development of radiative thermoregulatory materials (RTMs) and the rich accomplishment in the past decade. We also aspire to spark more research efforts by discussing the knowledge gaps to be overcome in the near future, ranging from the developing comprehensive wearable-centric photonic theoretical models and multifunctional design realization to cross-disciplinary real-world demonstration and validation of the performance and benefits.
