New smart ring detects whether a drink has been spiked

Researchers from the University of Tartu Institute of Computer Science have developed "Hedgehog," a smart ring prototype that can detect tampering with a beverage. The ring can tell whether liquids, such as juice or beer, contain drugs or other admixtures.

"Hedgehog" can detect spiked drinks with an accuracy of up to 89 percent. A green signal means the beverage has not been tampered with; a red one means it has. The container, however, must be transparent or translucent as the ring uses optical sensors.
