It still way off in the future.
A team of researchers in chemistry, pharmaceutics, and engineering is developing a long term implantable biosensor that could dramatically change the way of life for millions of people diagnosed with diabetes.
Prototypes of the device are smaller than a grain of rice yet embedded with an array of highly sensitive, microscopic electronic chips, sensors, and transmitters.
The device would be injected into a diabetic patient subcutaneously using a hypodermic needle. Patients would then wear a special watch-like monitor that would receive transmissions from the sensor so they could track their blood sugar level throughout the day.
