PRINTED ELECTRONICS: THE FUTURE IS FLEXIBLE

Chances are that most of us have used a printed electronic device, whether it's a security tag on a piece of clothing, or a plastic badge used to open the door of our workplace. Printable electronics have diverse potential applications in flexible solar cells, batteries, sensors, lighting products, medical diagnostic devices, drug delivery devices, smart packaging and clothing, and displays. Following are several innovative applications incorporating printable electronics. Low-Cost Printable Electronics FabricationThe need for low-cost and environmentally friendly processes for fabricating printable electronics and biosensor chips is rapidly growing. NASA has developed a unique approach for an atmospheric pressure plasma-based process for fabricating printable electronics and functional coatings. This system involves aerosol-assisted, room-temperature printing in which an aerosol carrying the desired material for deposition is introduced into a cold plasma jet operated at atmospheric pressure.

Laser Vision Helps Package Shippers See Clearly

An analyzer developed for Hubble mirror testing helps FedEx scan packages.For more than 25 years, the Hubble Space Telescope has provided stunning photos of the universe unequalled in their depth, detail, and distinction. But in its early days, Hubble wasn't capable of sending back such breathtaking photos. Within weeks of launch, the images beamed back to Earth were fuzzy and out of focus. It was determined that Hubble's primary mirror had been ground to the wrong shape and was too flat by 2.2 micrometers, causing reflected light from the edge of the mirror to be focused on a different point than light coming from near the center. It was determined that the device used to create the nonspherical mirror had been incorrectly assembled, and the mirror's manufacturer had failed to notice the problem before Hubble was launched.

Farzin Amzajerdian, Principal Investigator, Langley Research Center, Hampton, VA

Since 2003, Farzin Amzajerdian has worked on the Navigation Doppler Lidar (NDL), a sensor designed to support safe and precise vehicle landings on Mars and other destinations. The breadbox-sized NDL contains three lasers, a small electronics box, and lenses connected by fiber-optic cables. Amzajerdian will soon oversee the testing of the technology in California's Mojave Desert.

The Basics of Encoder Selection

Positioning: Resolution and AccuracyAn application’s required positioning resolution dictates the choice of encoder resolution. A well-tuned system can maintain the position within one encoder state (quadcount). Therefore, the encoder resolution in quadcounts (states) should at least correspond to the maximum permissible positioning error. Depending on the response time of the system, a higher encoder resolution should be chosen for the controller to detect deviations faster and counteract quicker.

Branimir Blagojevic, Technologist, Goddard Space Flight Center, Greenbelt, MD

During his time with former employer Science and Engineering Services, LLC, Branimir Blagojevic helped build a remote-sensing device that detected biological agents. The technology, originally made for the Department of Defense (DoD), may soon find a place on Mars. Blagojevic currently leads the development of the Bio-Indicator Lidar Instrument (BILI), a device that could be used to spot organic molecules and signs of life on Mars.

Laser Diode Modules

BEA Lasers (Elk Grove Village, IL) has introduced two new low-profile additions to their rugged MIL Series of laser diode modules. The new MIL RA Model features a right angle, and the new MIL Compact Model features a straight housing. Both new models utilize a low profile 3/8” rugged laser housing, fitted with a M12 connector, 2 meter long PVC jacketed cable, and integrated power supply. The optional sensor-style bracket, or multi-adjustable “LB” bracket, completes the laser system. The new MIL Series laser diode modules are offered with standard 515nm (green) or standard 635nm (red), with 1mW or 5mW.
