Description
Junbo Jung and co-authors build a fast light meter to watch cooling films switch in real time, in a 2025 study. Films that cool by radiating heat can now flip their clarity when wetted, yet slow bench tools miss the flip as it happens. Their system reads light passage in a third of a second.
Checks against a standard bench meter showed errors under three percent. Repeat runs stayed tight as well. With the meter, the team varied solvent thickness and match to find what sets flip speed. A vacuum step that pulls fluid in lifted the wet state clarity past eighty-five percent within five minutes. The tool aids design of smart cooling skins.
