 a jewellery of health in the neck

Recently, researchers from Ohio State University in the US succeeded in creating such a necklace, which will not only enhance the beauty of your neck, but will also monitor health. 

This necklace is a battery-free biochemical sensor, which will detect blood sugar and glucose levels through the sweat of the human body. 

Instead of a battery, it has a resonance circuit and the device is named 'Smart Necklace'.

The female participants in the research took a 15-minute break and drank sweetened beverages after about half an hour of indoor cycling. During this, this device was worn around his neck. The sensor managed to accurately detect the glucose levels in the participants.
