A US healthcare company has revealed the world's first glucose sport biosensor, which takes blood sugar readings and displays the results on a smartphone.
The 'Libre Sense' device, developed by Illinois-based firm Abbott, is a round white biosensor, about the size of a £2 coin, that attaches to the back of the upper arm.
Upon application, it inserts a tiny 0.2-inch filament just under the skin, held in place with a small adhesive pad, to provide continual blood readings.
Application and removal of the sensor, which is set to start shipping this December, is pain-free, the company says.
Wearers automatically receive real-time glucose data, streamed every minute to an associated app via Bluetooth, when they tap their phone against the sensor.
The eerie Black Mirror-esque device is just like 'having a molecular laboratory on your arm' and provides a 'window into your body'.
The biosensor is applied to the back of the upper arm with a simple, disposable product called an applicator
Abbott is aiming to help athletes track the connection between blood sugar levels and performance with continual updates.
Tracking and understanding glucose levels enable athletes to refuel appropriately with sugar boosts during their workout.
Maintaining a stable glucose level during exercise helps manage energy supplies and avoid muscle fatigue.
Libre Sense is based on Abbott's glucose monitoring technology FreeStyle Libre, which was originally developed for people living with diabetes.
This is the first personal-use product based on FreeStyle Libre sensing technology that allows for use beyond diabetes, Abbott claims.
'Our breakthrough sensing technology has the potential to go beyond glucose and provide a lens into what's happening in the human body,' said Jared Watkin, senior vice president for diabetes care at Abbott.
'This could provide meaningful insights into other conditions, treatments and ultimately improve health.'
Libre Sense, which needs to be replaced after 14 days, can be worn while cycling, running, exercising, swimming, bathing and showering.
Abbott stressed that that Libre Sense is solely for sports use and is not intended to be used to diagnose or treat diseases.
Application and removal of the sensor is pain-free. It has a thin, flexible filament that's inserted under the skin to accurately measure glucose levels inside the body from the interstitial fluid - a thin layer of fluid surrounding the cells of the tissues just below the skin
The device has been tested to withstand immersion in up to 3 feet (one metre) of water for up to 30 minutes.
It's attached to the back of the arm using a disposable product called an applicator, which creates a small puncture.
According to Abbott, application was generally, if not unanimously, thought to be pain-free in tests.
The firm found that 91.6 per cent of 119 users surveyed agreed that it
