Although some wheelchair users could conceivably make use of devices like the GoPad, a researcher at Purdue University has developed a motorized wheelchair tray that looks to be a better option for giving wheelchair users convenient access to mobile devices. Employing a motorized arm, the “RoboDesk” can deploy or retract a tablet or lightweight laptop computer as needed. Read More
Transparent electrodes are in and of themselves nothing all that new – they’re currently used in things like touchscreens and flat-screen TVs. Thanks to research being conducted at Indiana’s Purdue University, however, a new class of such electrodes may soon find use in a variety of other applications, including flexible electronic devices.

Attachable stands or (less affordable) devices like the WeBike make it possible to exercise both body and mind while pedaling on the spot, but those pounding away on a treadmill are pretty much limited to listening to music or zoning out in front of a TV screen to keep their minds occupied. That could change with a new system developed by researchers at Purdue University. Called ReadingMate, the system uses head-tracking technology to keep onscreen text bobbing along in unison with the runner’s eyes. Read More
Researchers at Georgia Institute of Technology and Purdue University have developed new solar cells based on natural substances derived from plants, including trees. The organic solar cells have an efficiency of 2.7 percent – a new high for cells on substrates derived from renewable raw materials – and can be easily recycled. Read More
The fastest serve ever recorded by a ping-pong player moved at about 70 mph (113 km/h). Professor Mark French of Purdue University's Mechanical Engineering Technology department and his graduate students, Craig Zehrung and Jim Stratton, have built an air gun for classroom demonstrations that fires a ping-pong ball at over Mach 1.2 (900 mph or 1,448 km/h). As the picture above shows, that's fast enough for the hollow celluloid balls to blow a hole through a standard paddle. Read More

We know how it is. You can’t help but like the taste of fried food, but ... darn it, the stuff just isn’t good for you. Well, you may soon be able to eat your fried food without quite so many worries. A food scientist at Indiana’s Purdue University has created a “radiant fryer” that results in fried food with all the flavor, but up to half the fat and fewer calories than would otherwise be present.

The world may not be your oyster, but thanks to technology being developed at Indiana’s Purdue University, it may soon be your multi-touch screen. Researchers at that institution have created an “extended multitouch” system, that consists of a computer, video projector, and Kinect camera – the technology allows any surface to be transformed into a touchscreen interface, that can track multiple hands simultaneously.

One of the great things about 3D printers is the fact that they allow anyone to become a manufacturer of small items. Unfortunately, however, they don't allow anyone to become a competent structural engineer – just because you can whip up a three-dimensional design on your computer doesn’t mean that it will translate into a sturdy physical object. That’s why researchers from Purdue University and Adobe's Advanced Technology Labs teamed up to create a program that automatically alters such designs, adding strengthening features to them before they get printed.

Transdermal patches are currently used for the controlled release of medication, as long as that medication is made up of molecules that are small enough to be absorbed through the wearer’s skin. For solutions with larger molecules, scientists are looking into the use of patches incorporating arrays of skin-piercing microneedles. In many of these cases, however, the patches would require some sort of tiny battery-operated pump, to push the medication through the needles. Now, researchers from Indiana’s Purdue University have developed what could be an alternative – microneedle patches that use the wearer’s own body heat to deliver the drugs. Read More
Scientists may have hit upon a new means of predicting solar flares more than a day in advance, which hinges on a hypothesis dating back to 2006 that solar activity affects the rate of decay of radioactive materials on Earth. Study of the phenomenon could lead to a new system which monitors changes in gamma radiation emitted from radioactive materials, and if the underlying hypothesis proves correct, this could lead to solar flare advance warning systems that would assist in the protection of satellites, power systems and astronauts.
