Slimme 3D-geprinte melkdop waarschuwt bij bederf

UC Berkeley engineers are expanding the portfolio of 3D printing technology to include electrical components. They have put the new technology to the test by printing a wireless “smart cap” for a milk carton that detected signs of spoilage using embedded sensors.
Polymers are poor conductors of electricity, and thus bad candidates for electronic devices. To get around this, the researchers started off by building a system using polymers and wax. They would then remove the wax, leaving hollow tubes into which liquid metal – they used silver – was injected and then cured. An article about the research is published in Microsystems & Nanoengineering (Nieuwsbericht UC Berkeley, 20 juli 2015).
