An implantable sensor has been developed by researchers that measures blood sugar continuously and transmits the information without wires. Experts have said that this invention is a milestone in the treatment of diabetes.

There have been trials in pigs for about 31 years and in one pig the device has been working without any problem for more than a year.

This invention makes diabetes getting close to development of an artificial pancreas.

The team at the University of California San Diego and nearby privately held GlySens Inc said that this would be of great benefit to those who have to constantly monitor their blood sugar levels such as patients with type II diabetes.

Bioengineering professor David Gough, who led the study, said, "You can run the device for a year or more with it constantly working, and recording glucose quite satisfactorily. We hope to begin the first human trial in a few months.”

Type I diabetes currently affects about three million Americans. Type I is usually diagnosed in childhood or in young adults.

And about 180 million people world wide are suffering from Type II diabetes.
