WELT is a smart wearable healthcare belt that looks like a normal belt, thus offering consumers a more discreet way of using smart sensor technology to monitor their health. WELT is capable of recording the user’s waist size, eating habits and the number of steps taken, as well as time spent sitting down. It then sends this data to a specially-designed app for analysis, and the production of a range of personalized healthcare and weight management plans. The belt chargers similar to a smartphone and lasts for more than 20 days. It’s available for both men and women, and users can buy one for $69.
