Last-modified researchers found that you may have been created from the way current charging cell phone and capture the microwave signals and turn them into power microwave signals. From the Duke University team said the technology they were using solar panels more efficient and had been. Capture and devices Metamaterials wave energy they created various forms, use the conversion of other applications. In the future, satellite, sound or Wi-Fi signal able harvest, according to researchers in the United States. ' Is showing. You can avail of these consumer applications in materials ' engineering students Alexander Katko said.
By using glass fibers on the circuit board with copper conductors, researchers 7.3 volts of electricity into microwave oven will be. Offer to charge battery USB charger, mobile phone and camera frequently used about 5 volts. "We were aiming for the best we can achieve energy efficiency" said Allen hawks team members. "Energy efficiency we were getting about 6-10% in this design to 37% in solar cells what to achieve and was able to dramatically improve the energy conversion is on equal footing." Metamaterials are artificial materials to display properties in nature not normally seen.
Alexander Katko and Allen hawks design power harvesting devices. Building of the two students and their colleagues Steven camer phone and technology in the future can hope. Mobile phone when not in use so that to charge wirelessly. And that can help users who live in remote areas they are without access to the power grid also believe. They are "" be able to harvest energy from the signal generated by the cell phone towers. "Our work shows easy and inexpensive approach to harvest electromagnetic force", said Mr. Cummer. "Beauty of the design is basic building blocks is a self-contained and additives. Increase the cleaning power that can be assembled in just one more blocks. " Full report will be published in the December journal applied physics letters.
