Improving Medical Devices with Force Sensing Technology

This white paper explores the exciting new trend toward designing smart medical devices that provide critical force feedback to eliminate guesswork, improve outcomes, and increase consistency. Technical topics covered include the unique advantages of force sensing resistor technology over traditional technologies such as strain gauges and load cells. These advantages include simpler electronics, wider dynamic range, ease of integration, and lower cost. The white paper highlights how thin and flexible sensors have enhanced a wide range of medical device applications by providing force feedback and making the products smart.

Wearable Nanowire Sensors Monitor Electrophysiological Signals

Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the “wet electrode” sensors used in hospitals, but can be used for long-term monitoring and when a patient is moving.

Mini Solar Observatory Can Be Used on Manned Spacecraft

Southwest Research Institute (SwRI) developed a miniature portable solar observatory for use onboard a commercial, manned, suborbital spacecraft. The SwRI Solar Instrument Pointing Platform (SSIPP) uses a classic, two-stage pointing system similar to larger spacecraft, but in this case, the first stage is a pilot who initially steers the instrument toward the Sun. SSIPP does the rest, locking onto the Sun to allow observations. The first SSIPP spaceflight will search for “solar ultrasound,” a phenomenon first observed in the early 2000s by the Transitional Region and Coronal Explorer (TRACE) spacecraft. The ultrasound is sound waves with a 10-second period, some 18 octaves deeper than ultrasound on Earth, and forms visible ripples in the Sun’s surface layers. The waves are difficult to detect without space instrumentation because the tiny, rapid fluctuations cannot be separated from the confounding influence of Earth’s turbulent atmosphere. Although at first SSIPP will be operated from inside the cockpit, a full system eventually will be mounted outside the host vehicle to enable UV and X-ray observations that are inaccessible from the ground.

New Serenity Payload Detects Hostile Fire

Two government-developed sensors are working together to increase the security of deployed soldiers. The Firefly and Serenity sensors employ government developed algorithms, software, and hardware to locate hostile fire around a base. The technology, a joint effort between the Army Aviation Research, Development and Engineering Center, or AMRDEC, and the Army Research Lab, referred to as ARL, has been under development for more than a decade.

Products of Tomorrow: January 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Magnetic Thermometer for High-Resolution 10-mK Scale Thermometry

Device features improved sensitivity. Goddard Space Flight Center, Greenbelt, Maryland A thin-film magnetic thermometer with integrated, superconducting quantum interference device (SQUID) readout has been designed for fast, precision temperature measurements in the 10-mK range. The compact magnetic thermometer consists of a miniature DC SQUID susceptometer with a dilute paramagnetic alloy deposited in one of the two series-configured, gradiometric SQUID pickup loops that form the SQUID inductance. Directly sensing the magnetic signal with the SQUID eliminates coupling losses that occur by transformer-coupling the signal to a remotely located SQUID, usually operating at a higher temperature, and consequently, with a higher noise floor.

High-Temperature Ultrasonic Probe for In-Service Health Monitoring of Steam Pipes

The probe monitors the height of water condensation in steam pipes through the wall of the pipe. NASA’s Jet Propulsion Laboratory, Pasadena, California This ultrasonic, pulse-echo probe can sustain as high as 250 °C, and uses a piezoelectric transducer to generate and receive the ultrasonic pulses. The transducer is made of a piezoelectric material with high Curie temperature, and the probe is configured such that it is operated as air-backed and, thus, has minimum losses of power.
