It's a prototype of a belt that will automatically loosen when the wearer sits and tighten when he/she stands.
The Belty will also automatically expand if you've eaten too much, and tracks your waistline measurement, offering advice when it's time to shed a few pounds.

The belt has been developed by French company Emiota, which specialises in wearable tech (or "awarable" tech, as the firm calls it).

It's still only at the prototype stage, but Emiota said it hopes to have the Belty on the market by the end of the year.
