- 3D printing technology could make electronic circuits that are cheap enough to be added to disposable food packaging, creating a spoilage alert.
- The tricked-out milk cap detected changes in electrical signals in a carton left unopened at room temperature for 36 hours. The electrical changes indicated room temperature milk went bad significantly faster than refridgerated milk. (Duh.)
- The research was done by UC Berkeley engineers in collaboration with researchers at Taiwan’s National Chiao Tung University.
