High-tech paints record pressure sensitivity

22389198_SHere’s a “sensational” development that could impact the signage world: A high-res pressure sensor that gives a colored-coded response to touch.

The technology uses sensors to reveal the levels of stress applied to a surface, displaying the result through a color change.

As nano particles interact with light, they record pressure sensitivity and will change color. Imagine a touchable sign that entertains as well as informs through the language of changing colors.

While the intention of researchers was to reveal underlying pressure, discovering hidden stress points in manufacturing could prove useful across many industrial applications. These particles have unique properties, forming long strings of very small particles known as nano particles

Signage is both an age-old marketing tool and a high-tech method to communicate, inform and influence. The field of interactive signage is undergoing rapid growth as businesses search for environmentally friendly marketing solutions and sophisticated ways to communicate with passersby in that brief window afforded the average shop owner.

The research was conducted through a grant from the National Science Foundation. It will be interesting to see how these developments impact the world of signage amid an ever-changing marketing landscape.
