Smart Lid Systems: An innovative thermochromic coffee-cup lid

Australian firm Smart Lid Systems has invented a disposable coffee-cup lid that changes colour to indicate the temperature of the drink in the cup. It also indicates whether or not the lid is properly attached.

The smart lid alerts consumers their coffee may be too hot by changing from a dark coffee color to a bright red when the lid is applied to a hot drink. As the drink cools, the color of the lid changes back to the regular coffee color.
