Wellington: A new smart necklace has been recently developed that tracks people's food and drink consumption to prevent overeating.

The WearSens, a close-fitting metal necklace, is able to determine what a person is putting in their mouth by measuring the vibrations that occur as the food is swallowed and digested, Stuff.co.nz reported.

According to Popular Science, as a substance moves down the throat, it creates tremors that can be felt on the skin around the neck. The necklace's piezoelectric sensors are sensitive to mechanical disturbances and are able to record these vibrations.

The device is able to distinguish between solid and liquid food 90 per cent of the time and it could distinguish between hard and soft foods roughly 75 per cent of the time.

The study is published in IEEE Sensors Journal.
