Printing: security & sensory

Britain's new £1 coin

With an estimated 45 million fake £1 coins in circulation, Britain gets what is claimed to be a fraud-proof coin as the Royal Mint releases 1.5 billion one-pound coins that feature a 12-sided bimetallic design, a hologram and other discrete anti-counterfeiting measures. A different printing milestone emerges at Massachusettes Institute of Technology with the recent 3D printed autonomous sensory composite robots, that are provided with sensor laden robotic skin that can feel. 

Security features for the new coin include not only the 12-sided bimetallic design, but a  hologram, fine lettering and some other devices to beat crooks. Mint CEO Adam Lawrence (right) declares it “the most secure circulating coin in the world.”

Research curator Chris Barker points out that the history of British money started around 200 B.C. “Newton’s legacy at the mint was creating a better-designed coin in terms of physical design. The more intricate, the harder it is to replicate.”

A different printing milestone emerges with the recent 3D printed autonomous sensory composite robots, that are provided with sensor laden robotic skin that can feel.  Sensorimotor pathways in nature integrate multiple materials and functions in three dimensions.  One such pathway in golden tortoise beetles enables them to modulate colour in response to external disturbances.

Inspired by this, (left) Subramanian Sundaram and co-workers in the CSAIL (Computer Science and Artificial Intelligence Lab), Massachusetts Institute of Technology have demonstrated  a fully 3D-printed composite that operating at 1.5 V can sense strain, electrically amplify the signal, and respond optically.
