Nomads & Nano-Materials: combining LEDs with textiles

June 29, 2005
A series of Portable Light prototype designs combine Mesoamerican weaving traditions and solid-state electronics.

Reading Mat A university group in the US has created a series of prototype light-emitting textile designs using white LEDs, flexible thin-film photovoltaics and polymer batteries in combination with ancient Mesoamerican weaving traditions.

Portable Light prototype designs from the Nomads & Nano-Materials Project at the University of Michigan were exhibited at Nextfest 2005 in Chicago, where leading R&D labs, companies and visionary innovators from around the world gather to show their work.

The light-emitting textile designs have been developed by the Project for the nomadic Huichol (Wirrárica) people of the remote Mexican Sierra Madre Mountains. Portable Light applies creative processes and strategic thinking to optimize the performance of existing semiconductor technologies and create new applications to serve the large number of people - more than 2 billion - who do not have access to electric light or power.

The designs are completely self-contained, portable, off-the-grid light engines that can be deployed at a global scale wherever energy-efficient electrical power and illumination are needed.

Among the prototypes are a portable workshop; a community power bag, a portable, folding reading stool and a portable reading mat. Try on a light emitting garment that is a wearable workshop, roll up a reading light, sit on a folding stool that creates its own light, or pick up a portable power plant that weighs less than four pounds.

Reading Stool The Portable Light project was initiated and developed by Sheila Kennedy, Principal Investigator and Visting Saarinen Professor at the University of Michigan, in collaboration with industry leaders, academic research institutions and MATx, the pioneering materials research unit of Kennedy & Violich Architecture, Ltd. (KVA).

“By developing a new material medium for digital light, the Nomads project demonstrates the advantages of an energy-efficient textile lighting infrastructure,” says Kennedy. “The prototypes produced by our research group are lightweight and easy to ship and transport [and] offer the production economies of large-run textile fabrication.”

Opportunities for participation

KVA is looking for industrial manufacturers with expertise in LED and photovoltaic technology who are willing to donate money or components to the Portable Light Project's sites in developing communities (e.g. Mexico's Huichol community).

Community Power Bag In return, these manufacturers would receive valuable real-world product performance data as well as learning about novel and specialized methods of deploying the technology that are derived from the community sites (e.g. textile weaving to incorporate LED technology).

According to the Portable Light Project website, "Manufacturers that support the Portable Light Project are industry leaders who take action for the greater good and gain valuable product performance data on weather resistance, UV penetration, electrical output and duty cycles for solid state and polymer technologies. [They] benefit from real world knowledge building in key issues of thermal management, charge control design, light output and optics generated by the Portable Light Project."
