Three Peruvian engineers design 'anti-infection bracelet' alerting its user when their hand approaches the face
The Peruvian engineers designed an “anti-contagion bracelet” that alerts with a sound when the hand approaches the face, the main form of contagion. The engineers plan to release a tutorial on social networks so that people with certain technical knowledge can build the same bracelet at home, estimated at 40 soles (US$15).
