For the more than 1 million Americans who live with Type 1 diabetes, daily insulin injections are literally a matter of life and death. And while there is no cure, a new device may help manage the disease.

Space environments are particularly harsh for the high-strength fibers NASA relies on for soft structures. Kevlar, Nomex, Nylon, and other synthetic fibers are broken down by exposure to the combination of vacuum, atomic oxygen, and ultraviolet radiation. Glass fiber offers unique advantages for...

Hot foods are psychologically pleasing. Food heating systems are currently part of the astronaut feeding program. An electrical method of heating foods during dispensing in space uses magnetic induction heating. The process is up to 95% efficient in converting...

Engineers in the NASA Goddard Space Flight Center Instrument Electronics Development Branch have developed a chopper-stabilized auto-zero amplifier capable of amplifying signals with extremely small amplitude originating from a thermopile-based infrared (IR) sensor. The instrument is self-adjusting in that it...

Technologies using stretchable materials are increasingly important. Yet, in general, it is not possible to control how they stretch with much more sophistication than inflating balloons. A method was developed that allows the calculated transformation of 2D stretchable surfaces into targeted 3D shapes.

The use of multifunctional composites such as mechanically reinforced, electrically and thermally conductive parts is of interest in a range of application areas. Especially interesting and important is where tailorability of function is achieved by strategic placement of materials with...

Oxygen adversely impacts food flavor and nutrition. NASA’s proposed five-year shelf life for astronaut food requires aggressive measures to minimize oxygen. Previously, NASA packaged foods in containers with a high oxygen and moisture barrier. These materials have limiting properties. They contain a...

A fabric was developed that converts kinetic energy into electric power. The greater the load applied to the textile and the wetter it becomes, the more electricity it generates. The woven fabric generates electricity when it is stretched or exposed to pressure. The fabric can currently generate...

While silicon carbide (SiC) is an ideal material for building ultraviolet (UV) photodetectors, the absorbed photons get recombined in the first few nanometers at the surface due to a large absorption coefficient in the 200- to 250-nm wavelength band....

NASA Langley Research Center has developed an innovative radiation shield made by layering metal materials in the Z-shielding method. It is a new, low-cost, and easy-to-implement method to protect CubeSat electronic circuits from ionizing radiation found in low...

Newly developed two-dimensional (2D) materials such as graphene — which consists of a single layer of carbon atoms — have the potential to replace traditional microprocessing chips based on silicon, which have reached the limit of how small they can get. But engineers have been...

Plastics are excellent insulators, meaning they can efficiently trap heat — a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic casings for laptops and mobile phones that overheat, in part, because the...
