Putting new energy into the future of fashion

23 May 2016

An ESA-backed start-up company is working with French fashion students to incorporate energy-harvesting devices in new space-inspired high-fashion designs.

The results will be unveiled on a catwalk at the London Science Museum on 25 May.

ESA’s Couture in Orbit initiative is bringing together five top European fashion schools with advanced textile and technology companies to explore the future of fashion.

UK’s Ravensbourne fashion school is working with Portugal’s iNanoEnergy start-up. Founded by a group of academics from Porto University, this young company is housed at ESA’s business incubator in the university’s Science and Technology Park.

“The human body generates about 120W of heat every day, and is in motion for prolonged periods,” explains the company’s Joel Puga.

“We have been developing micro- and nano-generators small enough to embed in clothes and shoes to generate power.

“The aim is to charge the batteries of sensors in the coming generation of smart textiles and shoes and, in the future, to charge smartphones and other devices.”

The miniature generators combine two technologies with space heritage. 

‘Thermoelectricity’ involves converting heat into electricity, often applied to power spacecraft in deep space from radioactive decay. 

‘Piezoelectricity’ generates electricity from compression or other mechanical stress, and is used in spacecraft sensors and actuators.

“For the time being we are looking into lighting up LEDs embedded in shoes,” adds Joel. “Instead of relying on batteries like the LED shoes you can buy today, these would be powered from our generators, so they would be environmentally friendlier as well as longer lived.”

iNanoEnergy is working with the Ravensbourne students to incorporate as much of its technology into the shoeware as possible.

“The result is going to be a surprise,” notes Joel. “We look forward to seeing it as much as anybody.”
