Wearifi is developing the world’s smallest, battery-free wearable device, using miniaturised sensors that are small enough to fit on fingernails . Its partnerships to date include one with L’Oréal, plus funding from the US Department of Defense and the National Institutes of Health.  Wearifi’s miniature wireless devices allow for imperceptible and unobtrusive placement practically anywhere on the body and are currently used to monitor heart rate, respiration rate and UV exposure.
