A research team at the University of Washington has developed a wearable device (shown here) to detect and reverse an opioid overdose. The device, worn on the stomach like an insulin pump, senses when a person stops breathing and moving, and injects naloxone, a lifesaving antidote that can restore respiration. The devices's sensor patch consists of two accelerometers to detect respiration and apneas, as well as a motor to activate the injector by pressing the activation button (shown here) in the event of an overdose.

A new device can detect when somebody stops breathing during an opioid overdose and inject the drug naloxone to restore breathing.
