Next-Generation Electronics Innovations for NASA’s Space and Commercial Future

In 1964, NASA’s Electronics Research Center (ERC) opened in Massachusetts, serving to develop the space agency’s in-house expertise in electronics during the Apollo era. The center’s accomplishments include development of a high-frequency (30-GHz) oscillator, a miniaturized tunnel-diode transducer, and a transistor more tolerant of space radiation. Another development was in the area of holography. At the ERC, holography was “used for data storage, and has permitted a remarkable degree of data compression in the storing of star patterns.”

2015 Create the Future Design Contest: Electronics Category Winner

Real-Time Fiber Optic Sensing System Lance Richards NASA Armstrong Flight Research Center Edwards, CA 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.
