Soon, simply walking or running with your iPod in your pocket could keep it powered and pumping tunes.
- Tapping the power of motion, scientists generate 1.26 volts of electricity.
- They created the first device to produce practical amounts of power from piezoelectronics.
- The power output could quickly jump high enough to power iPods and cell phones.
Every move you make, every step you take, you can generate electricity. By cramming 20,000 nanowires into three square centimeters, scientists from Georgia Tech have created the world's first device powered solely by piezoelectric materials.
A piezoelectric material is something that, when pushed or pulled, generates a mild electrical charge. Within three to five years piezoeleectric nanowires, woven into a cotton shirt or housed in a shoe heel, could charge a cell phone or laptop battery after even a short walk.
"This is a key step to designing technology that will be useful in the near future," said Z.L. Wang, a professor at Georgia Tech and co-author of two new papers in Nature Nanotechnology and Advanced Materials.
