LED drivers that receive their power from a single cell are receiving a great deal of attention. To generate the high voltage for illuminating a white LED from a low-voltage power supply basically ...

Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light. The devices are ...

In his recent demonstration, Wang's team grew 2.7 micron diameter zinc-oxide nanowires into arrays that were able to sense touch with a resolution of 6,300 dots per inch and a switching time of 90 ...

Parquet power: fungus-treated wood could soon be used to create energy-generating floors. (Courtesy: Pazzo4562/CC BY-SA 4.0) Infecting wood with wood-decay fungus can boost its piezoelectric output by ...

The RE46C101 is a piezoelectric horn driver and LED driver circuit designed for applications employing a self oscillating piezoelectric horn although it can be used in direct drive applications. It ...

(Nanowerk News) Researchers at the Georgia Institute of Technology want to put your signature up in lights – tiny lights, that is. Using thousands of nanometer-scale wires, the researchers have ...

Researchers want to put your signature up in lights. Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure – from a signature or a ...

August 19, 2013. Researchers at the Georgia Institute of Technology want to put your signature up in lights—tiny lights, that is. Using thousands of nanometer-scale wires, the researchers have ...

What do electronic signatures, fingerprint scans and touch-sensitive robot skin have in common? All three technologies may soon be advancing, thanks to a new system that turns an array of zinc oxide ...

In today's concrete jungle, pavement takes up a lot of space, so we might as well cram some smarts in there. Previously we've seen ground coverings that light up, absorb solar energy, generate ...
