Hackaday Prize Semifinalist: Helping Out In The ER

[Moldovanu] and [Radu] are out to fix emergency medical care in their native Romania. They’re developing a very inexpensive bracelet that keeps track of heartbeat, blood oxygen, and temperature of a patient, either in an ER or in the waiting room.

The Health Mate, as the guys are calling it, is a small bracelet loaded up with IR LEDs, photodiodes, a temperature sensor, and a WiFi module. They’ve wired all these parts up on a home made board, connected a battery, and are starting to measure their vitals.

It’s a simple device, but it’s simple for a reason: heart rate and blood oxygen saturation are some of the most important indicators doctors and nurses look at when triaging patients. By making their health monitor cheap and good enough, it eventually makes its way onto the wrists of more patients, and will hopefully save more lives
