Woven Nanotube Fibers Turn Heat into Power

Flexible thermoelectric generators could be a useful way to make carbon "green."

UV Sensors for Wearables Are Flexible, Sensitive

To make ultraviolet (UV)-detecting wearables, scientists have created a new type of light sensor that is both flexible and highly sensitive.

Tiny Solar Cells Deliver Big Power

Engineers at the University of Wisconsin-Madison have created microscale solar cells that could power a multitude of personal devices, including wearable medical sensors, smartwatches, and autofocusing...

NASA Tooling Techniques Enhance Medical Imaging

They can release as much energy as tens of billions of hydrogen bombs exploding at the same time. They send protons and electrons rocketing at near the speed of light. They heat gas in the...

“Smart” Sunglasses That Block Blinding Glare

The days of being blinded by glare from the sun, despite the $300 sunglasses straddling your face, may soon be over. Since 2003, Chris Mullin, PhD, and CEO of Dynamic Eye (Pittsburgh, PA), has...

Ultraviolet-Blocking Lenses Protect, Enhance Vision

In the 1980s, Jet Propulsion Laboratory (JPL) scientists James Stephens and Charles Miller were studying the harmful properties of light in space, as well as that of artificial radiation...

Multispectral Imaging Broadens Cellular Analysis
