Our sensors are used to develop new technologies in various industries due to their accurate heat flux measurement through many surfaces. Recently our gSKIN sensors have been used in a study focused on membrane-assisted radiant cooling. The associated article is authored by Eric Teitelbaum, Kian Wee Chen, Dorit Aviv, Kipp Bradford, and others. The article is published and is visible to the public on the Proceedings of the National Academy of Science of USA (PNAS) article page.

The article presents the cooling capabilities from a radiant cooling pavilion. As a non-conventional cooling method, the cooling effect is created through cooling surfaces rather than the air. Essentially the cooled surfaces cool people through thermal radiation. Today, there is a lack of radiant-cooling products on the commercial market. This is due to two main reasons, the low temperature required for radiant cooling in humid environments causes condensation, and the fact that cold surfaces will still cool adjacent air via convection, limiting overall radiant-cooling effectiveness. The study shows the contrary and provides proof-of-concept solutions examined for a transient thermal-comfort scenario. 

With the help of our gSKIN® BodyTEMP Patch accurate measurements of the individual’s temperature as well as heat flux from the wrist were recorded while in the cooling system. This data supported the observations of the temperature variations experienced in the radiant cooling apparatus. Please refer to the ‘Physiological Measurements’ section under ‘Results’ in the article for a detailed overview of the heat flux observations.

The results from this radiant cooling study display the ability to sustain people’s comfort within warm air environments. As stated in the article, this is “…a paradigm-shifting approach to thermal comfort that may help curb global cooling-demand projections.”

We would like to congratulate the authors and contributors for their great efforts towards this achievement, and we welcome you to explore more on our expertise and sensor solutions in our webpage.
