Assisting An Aging Population: Designing Medical Devices With Force Sensing Technology

With the geriatric population on the rise, design engineers are challenged with designing responsive, noninvasive, user-friendly medical devices that cater to the needs of an older generation. Patients are looking for cost-effective, easy to use assistive tools that help them regain independence and confidence in their everyday life. Force feedback is a key feature for many of these devices that provide the user and doctor with great insight that ultimately results in better quality of life for the patient. Medical devices with force feedback allow design engineers to create innovative products that differentiate them from the competition.

Hardening Electronics Against Difficult High-Temperature Environments

This technology provides extended performance for enhanced digital electronics while significantly increasing mean time between failures (MTBF). Silicon Space Technology (SST), Austin, Texas A new technology delivers temperature hardening in a number of products at the CMOS process level while increasing overall product reliability and longevity. Providing solutions that operate successfully in extreme temperature applications in the oil and gas, space, automotive, aerospace, and medical industries, as well as broader applications like industrial automation and high-performance computing, is paramount. As a result of the technology, system engineers are able to extend the limits of what’s possible in designing ruggedized and broader electronics for today’s extreme and difficult environments.

Stacked Capacitor Special Lead Adapter

Goddard Space Flight Center, Greenbelt, Maryland The current installation method for tall, stacked capacitors is very cumbersome because the lead form is very sharp and prone to solder cracking due to thermal cycling. An astringent installation process was developed to obtain the best chance of a successful solder joint with a proper heel fillet so the chance of cracking is minimized.

Nanoscale Vacuum Channel Transistor

Ames Research Center, Moffett Field, California This invention presents a nanoscale vacuum tube or vacuum transistor fabricated entirely using current silicon integrated circuit manufacturing techniques. Vacuum is better for electron transport than any semiconductor since there is no electron scattering. In addition, vacuum devices are immune to radiation. Nevertheless, vacuum devices lost out to silicon devices due to ease of large-scale manufacturing, robustness, versatility, and low cost. Here, the best of vacuum and silicon technologies are combined to produce nanoscale vacuum transistors that are amenable to large wafer fabrication and are inexpensive, while providing exceptional performance.

NASA Flywheel for iPad

John H. Glenn Research Center, Cleveland, Ohio NASA Flywheel is an augmented reality application intended to highlight NASA Glenn’s research efforts in the area of flywheel energy storage systems. The app utilizes a printed optical target, available on the GRC Flywheel Program brochure and through the NASA Glenn Web portal, to present users with 3D views of flywheel hardware and space applications. Additional video and imagery are also included in the application package. The software has been compiled and bundled as an iOS app for the iPad, and is intended for release through the Apple App Store.

Three-Dimensional Photovoltaics Array for Laser-Based Power Transfer

Potential applications include situations in which there is a need to create electrical power at a remote location. Goddard Space Flight Center, Greenbelt, Maryland A standard solar array is a flat panel configured of many individual solar cells, wired in series or parallel, depending on their junction configuration and material. Since the solar flux is constant depending on the distance from the Sun, the maximum energy conversion for a given solar panel depends upon the capability to absorb as many spectral peaks as possible (different materials) across the total solar spectrum. If the radiative source is a man-made device such as a laser, parked in a different orbit or on Earth, then the impinging intensity is narrow spectrally, coherent and accurately pointed, and capable of very high intensities. Thus, the materials can be tailored to match the incoming radiation for maximum absorption.

Nanowire-Based Piezoelectric Power Generation

Energy scavenging is appealing for powering sensors, and for charging cellphones and small consumer electronics. Ames Research Center, Moffett Field, California Sensors have improved in terms of size, capability, and power consumption, but their deployment in remote areas is limited by battery power supplies. Using piezoelectric (PE) materials for energy scavenging is a possible way to remedy the situation. The technology developed in this work converts existing sources of nonpolluting energy (mechanical strain) from nature into electricity. The quantity of energy produced is not massive, but it can be easily generated from free sources such as vibration and electromagnetic waves.
