Scientists at NASA’s Glenn Research Center have developed a circuit board that serves as a control and sampling interface to an inertial measurement unit (IMU). The circuit board provides sampling and communication abilities that allow the IMU to be sampled at precise intervals....

The Lunar Reconnaissance Orbiter (LRO) employs many advanced innovations developed at NASA’s Goddard Space Flight Center and in collaboration with other organizations. The applications and benefits for these technologies are advantageous for many other...

High-intensity focused ultrasound (HIFU) is a rapidly developing medical technology that relies on focusing acoustic waves to treat remote tissue sites inside the body without damaging intervening tissues. HIFU can be used to treat benign and malignant tumors, dissolve blood...

NASA’s Marshall Space Flight Center (MSFC) has developed compact, reconfigurable electronic devices to drive and control avionics instruments. Typical avionics systems function through centralized power distribution units (PDUs), which have complex, expensive, and time-consuming design, development, test, and...

NASA has developed a novel hybrid supercapacitor system utilizing vertical graphene as an electrode material grown directly on collector metals using a plasma enhanced chemical vapor de - position. Supercapacitors are an alternative to batteries for energy storage, offering high power density and...

Engineers at the Massachusetts Institute of Technology (MIT) have developed a way to prevent hydrogels from dehydrating. The water-based technique could lead to longer-lasting contact lenses, stretchy microfluidic devices, flexible bioelectronics, and even artificial skin.

Microwave power transmission using rectenna technology has attracted a strong interest in conjunction with wireless electric power delivery to infrastructure and subjects located at a remote place. A typical rectenna, which is a major...

High-temperature electronic integrated circuits have been demonstrated in silicon carbide (SiC) depletion mode MESFETs. This process is only capable of producing depletion mode n-channel MESFET transistors. With only this type of transistor, designing a logic gate is a challenge. A previous logic gate design that can be...

The objective of this innovation was to develop a methodology of fabricating thermopile detectors using standard semiconductor fabrication techniques. The goal was to develop a fabrication process that minimized the roughening of the Si legs during patterning of the metallic couples, and to...
