University of California Berkeley engineers have printed a
wireless "smart cap" for a milk carton, which was capable
of detecting signs of spoilage using embedded sensors.
Berkeley's innovation, for the first time, has used 3D printing
to produce sensitive electronic components.
The "smart cap" was fitted with a capacitor and an
inductor to form a resonant circuit which could detect the changes
in electrical signals that accompany increased levels of bacteria.
The researchers hope to adapt this technology for health
applications, such as implantable devices that can monitor drug
concentrations or muscle strain. The researchers' findings were
published in a new open-access journal in the Nature Publish Group
called Microsystems & Nanoengineering.
