“Dexcom recently announced that they have secured approval for the G5 continuous glucose monitor (CGM), a Bluetooth enabled implanted device that can sends data directly to your smartphone.

The fact that it can send data to a smartphone isn’t really that new. The prior version, the G4, already enabled data transfer to an iPhone app. That system had a sensor that tracked glucose levels and sent it to a receiver which could display the data as well as send it on to a smartphone or the cloud.

What’s changed with the G5 is that they’ve embedded Bluetooth into the sensor itself and taken the receiver out of the equation, helping lighten the load for diabetics using their CGM device.”
