Harnessing Everyday Motion to Power Devices

Harnessing Everyday Motion to Power Devices

Imagine powering your cell phone by simply walking around your office or rubbing it with the palm of your hand. Rather than plugging it into the wall, you become the power source. Researchers at the 247th National Meeting & Exposition of the American Chemical Society (ACS) presented these commercial possibilities and a unique vision for […]

Computer Processors Power Efficiency Increased

Computer Processors Power Efficiency Increased

Have you ever wondered why your laptop or smartphone feels warm when you’re using it? That heat is a byproduct of the microprocessors in your device using electric current to power computer processing functions — and it is actually wasted energy.   Now, a team led by researchers from the UCLA Henry Samueli School of […]

Making Frequency-Hopping Radios Practical

Making Frequency-Hopping Radios Practical

New hardware could lead to wireless devices that identify and exploit unused transmission frequencies, using radio spectrum much more efficiently.   The way in which radio spectrum is currently allocated to different wireless technologies can lead to gross inefficiencies. In some regions, for instance, the frequencies used by cellphones can be desperately congested, while large […]
