3D-printed ‘smart cap’ uses electronics to sense

spoiled food

UC Berkeley engi-

neers, in collabora-

tion with colleagues

at Taiwan’s National

Chiao Tung Univer-

sity, are expanding

the already impres-

sive portfolio of 3D

printing technology

to include electrical

components, such

as resistors, induc-

tors, capacitors and

integrated wireless

electrical sensing sys-

tems.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.

What if your fridge knew when the milk was off?

Professor Krishna Persaud of the University of Manchester is one of

the scientists currently looking for ways to teach machines to smell.

He has found a way to replicate proteins which respond to smell, and

in collaboration with a group at the University of Bari, IT, has coupled

them to the gate of a transistor.

UC Berkeley engineers created a ‘smart cap’ using 3D-

printed plastic with embedded electronics to wirelessly

monitor the freshness of milk.(Photo and schematic by
