Researchers in Britain say human trials will begin in 2016 on a new device that is about the size of a wrist-watch.
It is the world's first prototype artificial pancreas.
It is surgically implanted into the abdomen and will release a precise amount of insulin into the bloodstream.
The device includes a tube that runs from the implant to the outside of your body, where the patient replenishes the insulin supply.
The creator, Professor Joan Taylor, says the user does not need to fill it up every day.
The De Montifort University professor adds that it will help all Type-1 insulin-dependent diabetics and even some suffering Type-2 diabetes who require daily injections.
This prototype has taken 20 years and millions of dollars to develop.
If all goes to plan, the device could be ready for use in about a decade.
