Heat Sensitive Backing Turns Your iPhone Into a Giant Mood Ring – Well, Sort of

by Hazel Chua

Remember those mood rings and love compatibility cards that s0ld like hotcakes because of their cool color-changing properties? You know, where the ring or strip on the card changes color from blue to red or green, depending on your mood or how compatible two people are with each other… not.

Heat Sensitive iPhone Backing

In fact, the only thing those rings or strips measure is body heat. If you’re hot, it might turn red. If it’s exposed in a cold environment, it might turn blue. Now take this concept and apply it to RF Laserworks’ Heat Sensitive iPhone 4/4S Backing that turns your smartphone into some sort of heat-detecting (or heat-reactive) device.

Heat Sensitive iPhone Backing

The self-adhesive backing is just 0.005″ thick and covers the back of your iPhone 4 or 4S snugly. Expect it to remain black when you’re nervous (meaning your hands are cold) and deep blue (if you’ve got warm hands or are running some sort of fever.) The backing also turns yellow, red, or green all throughout the 90 to 95 degrees Fahrenheit temperature range.

The backings are available online from RF Laserworks for $11.99(USD) each and can be ordered with or without an Apple logo cutout.
