Natural clothing with solar-power chargers being developed at Colorado State University

Apr 17, 2012

Colorado State University apparel design and production researchers and students are working to develop natural-fiber outdoor clothing that can charge MP3 devices, tablets, computers, GPS units and cell phones with built-in -- but comfortable to wear -- solar panels. The project is so impressive that it was recently selected to compete in a sustainability design competition in Washington, D.C., from April 21-23.

The project intends to also reduce pollution on two fronts. First, the clothing will use the most recent research and technology to make natural fibers such as cotton and linen as outdoor savvy as other petroleum-based textiles which are heralded by outdoor enthusiasts for warmth, UV ray protection, comfort and moisture-wicking. Second, the clothing will provide a solar source of energy for , reducing alkaline battery use.

Eulanda Sanders and Ajoy Sarkar, associate professors in the Department of Design and Merchandising, along with four students, are currently developing natural-fiber outdoor clothing that harvest energy while the wearer participates in outdoor activities.

“This project is unique in that there are no current apparel products that combine solar power with ,” said Eulanda Sanders, a professor in the Department of Design and Merchandising who specializes in apparel design and production. While a few solar-powered “smart” outdoor apparel items are on the market, they are functionally flawed with solar panels that are difficult to launder or wear and are not aesthetically pleasing.

The team is using only UV-treated natural fiber fabric, such as cotton or linen, rather than petroleum-based textiles, which contribute to pollution. The researchers have discovered that the right selection of fabric and weave, thickness, weight, dyeing and finishing of natural fabrics provides excellent protection from UV rays. The group has developed prototypes of three jackets, a vest and two helmets --one ski helmet with Blue tooth capabilities and one for possible military use.

“We believe this will fill a need in the market for the many environmentally-conscious outdoor enthusiasts,” Sarkar said. The overall goal is to develop natural, solar-powering clothing items with functionality, durability and comfort while also being aesthetically stylish.

Undergraduate apparel design students Logan Garey and Anna Rieder, merchandising student Jared Blumentripp and engineering student Erick Guack, are collaborating to develop outdoor gear with .

Key factors in the success of these garments will include the cost and flexibility of the panels and strategic placement to maximize sun exposure. Comfortable and easy-to-launder panel attachment points and wiring also will be important design features. In the second phase of the project, they also are considering designs that could be later adopted by road construction workers.

The team will present their project and prototypes at the National Sustainable Design Expo in Washington, D.C. They will be among 45 teams selected from 150 team applications from across the country that were selected to compete in the U.S. Environmental Protection Agency’s People, Prosperity and the Planet student competition. If CSU students win, they’ll receive additional funding to market their idea.
