New Inkjet-Printed Antenna Harnesses Energy of Wideband Radio Frequencies
Manos Tentzeris, a researcher from the Georgia Tech School of Electrical and Computer Engineering has invented a new type of antenna that could make harnessing the energy of otherwise wasted radio waves more easy and could yield a higher efficiency on a broader range of frequencies.
Grad Student Finds Better WiFi Management That Could Save Power
Since its appearance on mobile devices, the Wi-Fi technology has been draining the battery of Windows Mobile, iOS and Android phones continuously. The drain is due to the fact that the more wireless devices are within an area, the more they need to be awake to make data transfers, since so-called "collisions" between them appear all the time.
Voltaic Spark: 8-Watt Solar Powered Carrying Case for iPads and Other Gadgets
I've been writing about Nokia testing a solar powered version of one of their cellphones just the other day, and thought it's a pretty stupid idea to apply solar cells on phones since they're kept mostly inside pockets, and they aren't transparent. Today I found out that a company called Voltaic is releasing a solar powered carrying case for tablets - the Spark.
Solar Powered Nokia C1-02 Cellphone Tested Around The World
Nokia is seemingly testing a solar powered phone these days in different conditions from different parts of the globe. They put four of their C1-02 devices, each having an attached solar panel and sent them to Kenya, the Arctic Circle, Sweden and to a boat on the Baltic Sea.
Thermoelectric Phone Charger Provides Electricity From Camp Fire
Hatsuden-Nabe is the name of a device that can charge up your cellphone by using wasted heat. It's available in Japan since yesterday and it surely attracts a lot of hikers and adventurers, who think this could save their lonesome journeys.
New Pyroelectric Device Transforms Heat into Electricity With 30% Efficiency
Thermoelectric devices transform waste heat into electricity and can one day provide increased efficiency for everything from small gadgets to power plants. Scott Hunter, working at the Oak Ridge National Laboratory (ORNL) hopes his new heat-recovering invention will scavenge lost heat with an efficiency of up to 30 percent.
Samsung Plans To Unveil Solar Powered Laptop
Right now I'm propped to a tree, writing this article, at the margins of an enchanting forest, with birdies singing everywhere. My laptop's battery is nearing its low percentage, and I'd really need some power source. I'd use Samsung's solar powered laptop, or at least the one they're planning to release in the not-so-distant future.
People in Developing Countries Could Charge Their Phones From Soil Microbes
Science should be used to benefit people and nowhere is that purpose clearer than in the new project led by a team at the Harvard School of Engineering and Applied Sciences: mobile phones could now be charged by putting them in contact with microbes living in the soil.
New Gallium-Nitride LED Technology Offers High-Power Lighthing
All of the LEDs you see in every device that you put your hands on is made with precious sapphire rock - artificially grown one, but still an expensive material to work with. A new technology developed by Bridgelux uses Gallium nitride to grow LEDs on silicon substrates and can be reproduced at commercial scales.
New Substrate for Graphene Could Finally Make It Useful and Electronics Greener
Graphene has lately been the electronic industry's spoiled kid - everybody wants to have a piece of the research, but few have the tools and inspiration to find something new. A team of researchers from the University of Arizona have found a material that can play the role of an insulator for the one atom-thick graphene layer. The team published their study in Nature Materials.
