The wearable HopeBand invention monitors the user’s blood oxygen levels to help prevent an accidental opioid overdose.
Developed by students at Carnegie Mellon University, the HopeBand’s onboard pulse oximetry sensors will detect low blood oxygen levels and trigger an alert if they do not improve within ten seconds. That alert is sent as a text message with the wearer’s location, increasing the chances of a quick emergency response and preventing an accidental overdose.
According to Rashmi Kalkunte, a software engineering student at Carnegie Mellon University in Pittsburgh, “Imagine having a friend who is always watching for signs of overdose; someone who understands your usage pattern and knows when to contact [someone] for help and make sure you get help. That's what the HopeBand is designed to do.”
