3D Printed Milk Lids Reveal Bad Milk

Milk. Some love it, some dislike it. We are told from a young age that calcium makes our bones strong and we are often told to have more. The experience can be a little daunting though for those unfortunate souls who have poured themselves a glass or over their favourite cereals only to have a foul taste and smell emanate from the white liquid they poured out (if it’s still a liquid).

This may be preventable through with the creation of the “smart lid”, a device that is hidden in plain sight. In fact, in the lid you place atop your milk. The device was created by researchers at the University of California and the National Chiao Tung University in Taiwan and aims to help people detect the quality of their milk before they open the bottle.

The lid detects changes within the milk which demonstrate that it’s going off, such as the presence of bacteria and can transmit these details wirelessly to devices such as smartphones and tablets. The resonant chips built inside the 3D printed caps means the caps don’t require a giant battery built in and can allow for low price monitoring and tracking of milk and possibly other foods.

Imagine going to the store and checking with your phone if the milk you just placed in the basket is good or if that sell by date was a really bad estimate for when it would go off.
