Wireless wearables powered by human skin
This scientist's vision is to invent devices that not only operate without batteries but take the concept of battery-less wearables one step further. In his mind's eye, the next generation of wearables will transfer power between wireless sensors using a far more efficient conductor - human skin.
Using artificial intelligence to track birds' dark-of-night migrations
On many evenings during spring and fall migration, tens of millions of birds take flight at sunset and pass over our heads, unseen in the night sky. Though these flights have been recorded for decades by the National Weather Services' network of constantly scanning weather radars, until recently these data have been mostly out of reach for bird researchers.
Smart Façades: Working from the outside in for energy efficiency
In an ongoing effort to reduce the carbon footprint of buildings, an interdisciplinary team of scientists and students is working to design and build more-sustainable building façade systems - so-called smart façades.
Tapping body heat to power smart garments
Some research has shown that small amounts of power can be harvested from a human body over an eight-hour workday, but the special materials needed at present are either very expensive, toxic or inefficient.
Fabric alternative to batteries
A major factor holding back development of wearable biosensors for health monitoring is the lack of a lightweight, long-lasting power supply. Now scientists report that they have developed a method for making a charge-storing system that is easily integrated into clothing for "embroidering a charge-storing pattern onto any garment."
Why a robot can't yet outjump a flea
When it comes to things that are ultrafast and lightweight, robots can't hold a candle to the fastest-jumping insects and other small-but-powerful creatures. New research could help explain why nature still beats robots, and describes how machines might take the lead.
Paving the way for a non-electric battery to store solar energy
Materials chemists have been trying for years to make a new type of battery that can store solar or other light-sourced energy in chemical bonds rather than electrons, one that will release the energy on demand as heat instead of electricity - addressing the need for long-term, stable, efficient storage of solar power.
Off-the-shelf, power-generating clothes are almost here
A lightweight, comfortable jacket that can generate the power to light up a jogger at night may sound futuristic, but materials scientists could make one today.
Reducing conducting thin film surface roughness for electronics
Surface roughness reduction is a really big deal when it comes to fundamental surface physics and while fabricating electronic and optical devices.
'Braidio' technology, lets mobile devices share power
A team of computer science researchers has introduced a new radio technology that allows small mobile devices to take advantage of battery power in larger devices nearby for communication.
Common soil bacteria creates nano sized conductive wires
Scientists have genetically modified a common soil bacteria to create electrical wires that not only conduct electricity, but are thousands of times thinner than a human hair.
A partnership to secure and protect the emerging Internet of Things
National Science Foundation and Intel Corporation team to improve the security and privacy of computing systems that interact with the physical world using a new cooperative research model.
Blades of grass inspire advance in organic solar cells
Using a bio-mimicking analog of one of nature's most efficient light-harvesting structures, blades of grass, an international research team led by Alejandro Briseno of the University of Massachusetts Amherst has taken a major step in developing long-sought polymer architecture to boost power-conversion efficiency of light to electricity for use in electronic devices.
A more efficient, lightweight and low-cost organic solar cell
Researchers have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the "electrode barrier."
Microbial nanowires capable of long distance electron transport
Researchers from University of Massachusetts Amherst have discovered an important characteristic of microbial nanowires - they are capable of long distance electron transport, a trait ideal for the development of renewable energy devices.
UMass Amherst Research Team discovers new conducting properties of bacteria-produced nanowires
