That's the technology developed by scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. Their implant, measuring just one-half inch by one-thirteenth of an inch (14 millimeters by 2 mm), transmits data to a smartphone via Bluetooth, ictnews.az reports.

The device, which can be implanted just under the skin and easily removed, contains several sensors coated with different enzymes. Each enzyme reacts to the presence of a different compound in the blood, whether pharmaceuticals, cholesterol, proteins, blood sugars or other substances.
