World's first light-activated, molecule-sized switch gets turned on

By - April 22, 2015 1 Picture
In the pursuit of ever-shrinking circuitry for nanotechnology electronics, increasingly smaller devices and components are being developed. Now researchers at the University of Konstanz and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) claim to have micro-miniaturized the humble electrical switch all the way down to molecule size and proven its operation for the very first time. Unable to flick such a tiny switch mechanically, however, the researchers instead used light to turn it on. Read More

V-One conductive ink printer aims to short-circuit electronic prototyping

By - February 10, 2015 9 Pictures
In designing and prototyping electronic circuit boards there is no quick or simple way to produce results. Many hours of design and development need to be expended on prototype layouts along with masking, etching, and populating those boards with components. Even after all of this, just one simple layout mistake can ruin all of your work and you have to go through the entire process again. The Voltera V-One aims to change all of that with the promise of a one button, conductive ink printing system solely designed to reduce the effort in rapid, small run hardware prototyping. Read More

oneTesla shrinks its singing Tesla coil kit to palm-friendly proportions

By - August 5, 2014 10 Pictures
The folks who successfully crowdfunded a DIY singing Tesla coil kit last year have taken to Kickstarter again to bring a smaller version into production. Like its older and bigger brother, the tinyTesla shoots out bolts of artificial lightning while playing MIDI music using the electricity itself. It looks like that polyphonic MIDI version of Danger High Voltage by Electric Six might just come in handy after all. Read More

One of the world's first integrated circuits goes up for auction

By - June 19, 2014 2 Pictures
If it weren't for the microchip, your smartphone would be size of a building and need its own power plant to work. Thanks to the integrated circuit and its modern incarnation in the microchip, electronics are a bit easier to carry around than that, and this week, Christie’s put one of the very first integrated circuits up for auction. Designed and constructed in 1958 by Texas Instruments, it's one of the three earliest "chips" ever made and went on the block with an estimated value of up to US$2 million. Read More

Chibitronics connects circuits with stickers for entertaining electronic education

By - January 22, 2014 14 Pictures
"Cute circuitry" is not a term you hear often – if at all – but it could be used to describe Chibitronics, which is a crafty merging of electronics and paper. The system combines familiar adhesive stickers with electronic components, such as LEDs, sensor circuits, and even a programmable microcontroller, to create a play set that educates while adding some flash to one’s works of art or otherwise mundane birthday cards.

ETH Zurich researchers create ultra-thin, flexible circuit

By - January 8, 2014 4 Pictures
Researchers at the Swiss Federal Institute of Technology in Zurich (ETH Zurich) have created clear, flexible electronic circuitry that is so thin it can sit upon the surface of a contact lens, or be wrapped around a human hair. The research, led by Dr. Giovanni Salvatore, could ultimately be used for implantable medical devices. One such potential application suggested by the team is a “smart contact lens” that could monitor intraocular pressure for glaucoma patients. Read More

The paper is the circuit: Scientists create graphite-based paper circuitry

By - May 16, 2013 3 Pictures
Given the low costs and extensive applications that could be possible with flexible paper circuit boards, we've seen many ideas for their production, from printing with silver ink to embedding chips within paper. Now, however, scientists have developed an elegant method for selectively changing the very nature of the paper itself into conductive graphite. Unlike polymer-based flexible circuits, these paper circuits are, ironically, able to withstand the high temperatures generally used in the production of electronics. Read More
