Proteus Digital Health won FDA approval for what the company calls “the only device with an FDA-sanctioned claim for measuring medication adherence.” Proteus technology, the development of which we’ve been covering for a number of years now, uses tiny injestible sensors attached to drug tablets and a patch that can detect when they’ve been swallowed. The patch then uses its built-in Bluetooth antenna to share when every pill was swallowed with the matching smartphone app, which in turn passes the readings to family, caretakers, and the patient’s physician.
