Moisture Sensitive Holograms

16 02 2008

Researchers in Ireland have developed a unique solution to determine the air’s moisture content quickly and accurately through innovative use of holographic technology.

These researchers at the Dublin Institute of Technology have successfully fabricated a hologram that quickly changes its color in response to even slight fluctuations in humidity and is able to return to its original color once the moisture in the atmosphere dissipates!

The material used to create this innovative hologram is a self-processing acrylamide-based photopolymer on a glass substrate.
