In the very near future, you’ll be able to slide a tiny device into your clothing that will track your own motion to create power for electronic personal devices like cell phones and fitness trackers.
Researchers at Vanderbilt University’s Nanomaterials and Energy Devices Laboratory have developed the energy harvesting system, which forms electrical currents with every step, wave, jump and turn you take. Electricity can now be generated in a tiny device that draws power from human motion… and is small enough to fit in a piece of clothing.
Every move you make can be a source of power.
The little gadget is made out of multiple layers of black phosphorous just several-atoms thick. Utilizing battery technology, the machine generates electricity anytime it’s bent, pressed, or moved—as it would be, say, anytime your legs swung forward while walking.
