According to the US addiction technology website reported on July 22, consumers will not have to smell the odor to detect whether the milk has deteriorated. The 3D printed bottle cap can be used to monitor the freshness of the liquid in the bottle.
Researchers at the University of California, Berkeley and National Chiao Tung University in Taiwan have invented a "smart bottle cap" that detects whether food is spoiled. The cap uses 3D printed electronics, and the cap circuit and wireless sensor detect if the milk or juice is spoiled when the bottle's liquid contacts the cap.
The cap detects the presence of bacteria in the bottle and transmits the test results in real time via radio. This means that consumers can use the mobile app to check the freshness of the food before purchasing. Engineers have also found other uses for this technology, and it can also be used to monitor the pressure and drug concentration of external devices.
