FTNW: Implantable Glucose Sensor Research

Researchers are developing a tiny implantable wireless device to monitor blood glucose levels. (

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.


  1. Hello YDMV,
    I work for Diabetes Forecast magazine I would like to interview you about a topic you discuss in one of your older blog posts--it's an issue that is important to people with diabetes.
    Would you please email me at so I can give you more information and see if you are interested? I would very much appreciate your perspective as a parent of kids with diabetes, and would hope to speak with you this week.
    Thank you,

  2. why do they always go for a grand idea? why dont they take one step at a time?If they could make a cgm that lasted 10 days and was 80% smaller than the ones we have everybody would be ecstatic

  3. We have restarted Dex Sensors and had the go another 5+ days. Tape becomes the issue, and the site get itchy.

  4. well I was thinking more about the size of it and the size of the needle. thanks anyway!
