A new smart belt buckle may soon limit the days of discreetly trying to unbuckle your belt under the dinner table. “Belty,” the self-adjusting smart belt from the French startup Emiota, was unveiled at the Consumer Electronics Show last Sunday. The wireless smart fitness device takes the task out of your hands by loosening and expanding while in sync with your waistline.

Bertrand Dupla and Carine Coulm, Paris-based designers, equipped Belty with small sensors, an accelerometer, and a gyroscope to know just how much you’ve been moving and whether you need to be more active. The collection of motors inside the Belty, according to Mashable, is responsible for loosening and expanding based on your waist size. This facilitates the ability for you to have more breathing space when you sit and automatically tighten when you stand up again.

The smart belt syncs wirelessly to an app where you can input your waistline measurement. The app can be used to set maximum and minimum fittings to prevent the belt from becoming too tight or too loose when automatically adjusting. It also provides the luxury of recording your steps and exercise levels and syncing up with the app if you leave your fitness tracker at home.

"It will take your measurement trends over time, so if you happen to start putting on some weight, your cellphone app will link to it and start telling you 'maybe you should go on a diet,'" KC Cassily, a company representative, told Abt Electronics.

The smart fitness device primarily focuses on a wearer’s waistline, since it is one of the biggest indicators of health. A study published in the journal Diabetes found “abdominal obesity” was strongly correlated with an increased risk of type 2 diabetes, cardiovascular disease, and death. This suggests people with larger waists are at high risk of premature cardiovascular disease and death than their trimmer waist counterparts, or those who carried weight around their hips and thighs.

The wearable tech device is considered an ideal product and less obtrusive by Coulm because the belt is "the only place you can add a lot of weight" to the device, making it a good place to load with sensors and other components, CNET.com reported. The prototype is only available in one color and style option, steel gray with a bright blue trim. The smart belt is likely to be a “high-end product,” with most likely a luxury price tag.

Belty is expected to hit the market by the end of the year with the prices to be announced.
