Real-Time Fiber Optic Sensing System

Lance Richards NASA Armstrong Flight Research Center Edwards, CA “The entire team of researchers who have dedicated years to the development of the FOSS technology is honored to receive this award. Since the beginning of our work, we wanted to create a better sensing system, making structural monitoring more comprehensive and lightweight. As we realized how broadly applicable FOSS was, we were inspired to keep innovating.“

A team at NASA Armstrong has developed fiber optic sensing system (FOSS) technology that represents a major breakthrough in high-speed operational monitoring and sensing. Driven by ultra-efficient algorithms, FOSS can be used to determine, in real time, a variety of critical parameters including strain, shape deformation, temperature, liquid level, and operational loads. This state-of-the-art sensor system delivers reliable measurements in the most demanding environments confronted by aerospace, automotive, and energy sectors. FOSS is ideal for monitoring the structural health of aircraft, buildings, and dams; improving the efficiency of turbines and industrial equipment; and detecting instabilities within tunnels and power plants.

Reducing Interconnection Weight in Autosports

In Formula 1 and other autosports, weight reduction is critical to competitive advantage. A few grams saved here and a few more saved there can add up to significant savings. There is also a move toward high-density packaging of electronics parts. As the electronics content of cars increases, the natural drive is to miniaturize the package to gain maximum efficiency in the use of space.

Magnetic Fluids Deliver Better Speaker Sound Quality

NASA’s liquid magnetization technology helps Sony increase sound amplitude while reducing distortion.

In the early 1960s, NASA scientists were trying to move fuel into an engine without the benefit of gravity. A scientist at Lewis Research Center (now Glenn Research Center) came up with the idea to magnetize the liquid with extremely fine particles of iron oxide. That way, fuel could be drawn into the engine using magnetic force.

Linear Motors

Heidenhain (Schaumburg, IL) offers ETEL ILF and ILM series ironless high-speed linear motors for use in the semiconductor and electronics industry. The motors utilize an ironfree coil design for zero-attraction force between the carriage and the magnetic way. The ILF is a smallersized motor for very high dynamic and low-moving mass applications; the ILM is a more powerful version of the ILF, and has an option to be air-cooled to increase continuous force output. The ironless motors come in a variety of lengths and heights with different degrees of force, and share the same profile so that one is interchangeable with the other. The motors can reach speeds of up to 20 m/s and peak force of up to 2,500 N. They are designed for direct drive applications and offer no backlash, fewer parts, and require no maintenance.

Self-Powered Intelligent Keyboard Could Provide Additional Security

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.

A Paradigm Shift for SMT Electronics: Micro-Coil Springs Interconnection for Ceramic and Plastic Grid Array Packaged Integrated Circuits

Jim Hester and Mark Strickland NASA Marshall Space Flight Center Huntsville, AL

Micro-coil springs (MCS) provide flexible electrical interconnections and allow significant movement in the x, y, and z axes to counteract the thermal expansion and dynamic forces between a microcircuit and a printed circuit board. Micro-coil springs are able to withstand harsh thermal and vibration environments significantly better than the current state of the art.

Researchers Develop Thinnest Electric Generator

Researchers from Columbia Engineering and the Georgia Institute of Technology made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.“This material—just a single layer of atoms—could be made as a wearable device, perhaps integrated into clothing, to convert energy from your body movement to electricity and power wearable sensors or medical devices, or perhaps supply enough energy to charge your cell phone in your pocket,” says James Hone, professor of mechanical engineering at Columbia and co-leader of the research.Hone’s team placed thin flakes of MoS2 on flexible plastic substrates and determined how their crystal lattices were oriented using optical techniques. They then patterned metal electrodes onto the flakes. In research done at Georgia Tech, a group led by Zhong Lin Wang, Regents’ Professor in Georgia Tech’s School of Materials Science and Engineering, installed measurement electrodes on the samples provided by Hone’s group, then measured current flows as the samples were mechanically deformed. They monitored the conversion of mechanical to electrical energy, and observed voltage and current outputs.Ultimately, Zhong Lin Wang notes, the research could lead to complete atomic-thick nanosystems that are self-powered by harvesting mechanical energy from the environment. This study also reveals the piezotronic effect in two-dimensional materials for the first time, which greatly expands the application of layered materials for human-machine interfacing, robotics, MEMS, and active flexible electronics.Source

Ferroelectric Materials Could Revolutionize Data-Driven Devices

Electronic devices with unprecedented efficiency and data storage may someday run on ferroelectrics — remarkable materials that use built-in electric polarizations to read and write digital information, outperforming the magnets that are inside most popular data-driven technology. But ferroelectrics must first overcome a few key stumbling blocks, including a curious habit of "forgetting" stored data. Now, however, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered nanoscale asymmetries and charge preferences hidden within ferroelectrics that may explain their operational limits.
