Description of Technology
This piezochromic button can be printed on to medical devices, packaging, or medicine containers to provide customers or medical professionals with a simple, intuitive, and built-in timing device. Simply pressing on the printed surface causes the device to change color. After a precise amount of time, the device reverts to its original color.

The colors and timing of the device are customizable at the time of manufacture and manufacturing costs are extremely low: just a few cents.

The device provides a distinctive visual cue for precise timing which is easy to understand and intuitive for consumers and medical professionals alike. It also reduces the complexity of medical procedures by removing the need for another separate timing device.

The color change duration can vary from 2 hours.

View the piezochromic device in action on a soap dispenser:

Watch how the center circle turns from red to clear after 30 seconds.

This unique and striking visual effect will stand out to consumers and leave a lasting impression.
