Thanks to engineers from the University of California/Berkley and National Chiao Tung University in Taiwan, you may never again have test your milk’s freshness by taking a whiff.

Using 3D technology, engineers have created a “smart cap” that can detect when food has gone bad.

According to Entrepreneur.com, the technology employs a 3D printed cap embedded with electrical components. When the liquid comes into contact with the cap, the resonant circuit is able to “detect changes in electrical signals caused by the proliferation of bacteria.”

In the past 10 years, a variety of 3D printed products have been created, ranging from vehicle parts, building materials, prosthetics and medical implants to toys and food. According to Berkeley News, the smart cap adds another item to the list: sensitive electronic components.

Researchers believe the technology can be expanded to test the freshness of all food.

“You could imagine a scenario where you can use your cellphone to check the freshness of food while it’s still on the store shelves,” said senior author Liwei Lin, a professor of mechanical engineering and co-director of the Berkeley Sensor and Actuator Center, in a statement.
