Google has filed a patent for a “'needle-free blood draw” smartwatch: it could be wearable or hand-held, and may eventually replace blood glucose meters.
The blood-sucking smartwatch would also cause as little pain as possible, even compared with the current glucose meters that ‘pin prick’ your finger.
Seems useful. It would really only benefit diabetics for a good while. There would have to be some sort of sanitizing method and a cartridge replacement.
Still, on demand blood glucose readings would be very helpful
