Samsung smart clothing from wellness belts to solar-charging bags (pictures)

Samsung's sister company, Samsung C&T, showed off its WELT smart belt; the Sol Bag, which charges a phone in four hours using solar power; and smart clothing, like a suit.

This bag has solar panels on the side to let you charge your Galaxy phone in about four hours.

It can't store sun power, though, so charging only occurs when you're in light. Samsung expects its bag to go on sale this year.

Samsung has long owned a men's suit line, which shares the same Galaxy branding as its smartphones. Now it has created suits with technology inside.

The Smart Suit has NFC in the wrist to do things like unlock your phone when you take it out of your pocket or let you exchange business cards digitally. You can also set different modes on your phone, like Office Mode and Drive Mode.

Samsung has already started selling the Smart Suit in Korea for about $500.

Along with a smart suit, Samsung C&T created a golf shirt under is Bean Pole Golf brand. It has similar functions to the Smart Suit and also can tell you the weather or the UV rating where you are.

The Samsung WELT, short for Wellness Belt, communicates with your phone to tell you how many steps you've taken, how long you've been sitting, eating habits and your waistline size.

The WELT sends data to a specially-designed app for analysis, to tell you things like -- if you keep eating like you did today, you're going to gain two pounds this month. Samsung expects the WELT to go on sale this year.

Samsung's Body Compass 2.0 workout suit contains six different kinds of sensors to track your fitness levels like heart rate, respiration and body fat levels. The company hasn't yet decided if it will release the product.
