The organic light emitting diode (OLED) array used in the OROM reader is made from organic compounds composed of lots of polymer chains with carbon, hydrogen, nitrogen, oxygen, and phosphorus atoms. They tend to be wickedly complex and large molecules, often with benzene rings and side chains of polymers attached to the main backbone.
For OLEDs, the side chains' energy absorption is what defines the properties of the light emitter. You adjust the material making up the polymer, tuning the emission wavelength. This material behaves like a semiconductor, which generally have material-defined, atomic energy bands to produce their distinct emission wavelengths when electrons change energy levels.
The polymers can be mixed up and spun onto a substrate at room temperatures. No clean room jazz, no extensive, and expensive, processing, implanting, nor semiconductor crystal growth environments. Just mix and paint. You can make 'em as small or as large as you want, or put them on flexible substrates. Serve and light.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
