Although still three to five years away, computers based on light signals instead of electrical signals might put the Pentium chip to shame. Since 1992, scientists knew that the holes in porous silicon contain microscopic structures that emit light when electric current is applied. But the untreated material was fragile. Oxygen and water molecules in the air interact with the surface and create a glass-like coating that disrupts its photoluminescence properties. Jillian Buriak, assistant professor in Purdue's Department of Chemistry, discovered a way to stabilize the substrate's surface by coating the porous surface of the silicon with Lewis acid, a solution which produces a greasy coating. "Because most current technology is based on silicon, it may be relatively easy to develop the optical applications and combine them with current technologies, as the manufacturing processes are already in place," Buriak says. Porous silicon could easily serve as a flat, display area for computer screens, as well as a basis for computers that operate on light signals.
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.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
