3D printing bottle caps can monitor liquid freshness

            3D printing bottle "before drinking a shake."

Future consumers will not have to smell the smell of a method to detect whether the deterioration of the milk, the use of 3D printing bottle cap can monitor the freshness of the liquid.

Recently, researchers at the University of California, Berkeley and a well-known universities in Taiwan have invented a "smart cap", this cap using 3D printing of electronic components, circuits and wireless sensor cap in the bottle of liquid from the bottle when the lid contact is detected whether milk or juice and other food spoilage. In addition, this cap can also detect whether the bottle of liquid bacteria, and real-time transmission of test results via radio. This means that consumers can use mobile apps before buying to check the freshness of food. Engineers have also found other uses for this technology, it can be used to monitor the pressure and concentration of the external device.
