A Fabric That Will Charge Your Gadgets.A stroll around the block in the right outfit could be enough to power your cellphone.Forgot your charger? No problem. Scientists have developed a microfiber fabric that can generate enough electricity to juice up a cell phone or a mini-music player. If turned into clothing, the fabric would get its power from the action of your daily movement. The material uses zinc-oxide nanowires that are arranged in pairs—one wire in each grouping is coated with gold, and serves as the electrode. When the fabric moves, the wires move and bend, and the fabric translates this mechanical energy into electricity.
GeneralAtlanta, GA – Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow.The nanogenerators take advantage of the unique coupled piezoelectric and semiconducting properties of zinc oxide nanostructures, which produce small electrical charges when they are flexed.GeneralAtlanta,Based on arrays of vertically-aligned zinc oxide nanowires that move inside a novel “zig-zag” plate electrode, the nanogenerators could provide a new way to power nanoscale devices without batteries or other external power sources.
“This is a major step toward a portable, adaptable and cost-effective technology for powering nanoscale devices,Nanogenerator allows us to harvest or recycle energy from many sources to power these devices.”
The nanogenerators take advantage of the unique coupled piezoelectric and semiconducting properties of zinc oxide nanostructures, which produce small electrical charges when they are flexed.Nanogenerator could produce as much as 4 watts per cubic centimeter – based on a calculation for a single nanowire. That would be enough to power a broad range of nanometer-scale defense, environmental and biomedical applications, including biosensors implanted in the body, environmental monitors – and even nanoscale robots.
Because zinc oxide is non-toxic and compatible with the body, the new nanogenerators could be integrated into implantable biomedical devices to wirelessly measure blood flow and blood pressure within the body. And they could also find more ordinary applications.
