Summary
A prototype tent converts bending, stretching and flexing of its fabric into electricity, aiming to supply low-power energy in shelters, disaster zones and remote camps.
In lab tests, a hand tap on a small textile sample charged a 0.22-microfarad capacitor to 5.8 volts in 1.5 seconds, showing the material can harvest energy from ordinary movement.
The design uses magnetoelastic ribbons in the floor and layered roof textiles with conductive fibers and magnetoelastic film, collecting power from wind, setup handling and people shifting inside.
Unlike solar panels, the system can keep generating after dark or in shade, but researchers say it is a supplemental source for LEDs, phone charging or small heaters—not high-drain devices.
Key hurdles remain around real-world output, durability after folding and weather exposure, and whether the textile can be manufactured cheaply at scale.
