Briefs: Test & Measurement
A spectral transmission-reflectance-intensity (TRI) analyzer was developed that attaches to a smartphone and analyzes patient blood, urine, or saliva samples as reliably as clinic-based...
INSIDER: Sensors/Data Acquisition
A transfer technique could allow high-performance gallium nitride gas sensors to be grown on sapphire substrates and then transferred to metallic or flexible polymer support materials. The process...
INSIDER: Test & Measurement
Scientists at the National Institute of Standards and Technology (NIST) have developed a new way to investigate the high-performance fibers used in modern body armor. The testing of soft body armor has been a big...
INSIDER: Sensors/Data Acquisition
iSoft, a new type of soft and stretchable sensor, is capable of sensing in real time, and can perform “multimodal” sensing of stimuli such as continuous contact and stretching in all...
INSIDER: Test & Measurement
In the future, breathalyzers will not just be used by police checking for alcohol intoxication, but also for testing the condition of athletes, and for people who want to lose weight. When exactly the body...
INSIDER: Test & Measurement
Before volcanoes erupt, there are often warning signs. Using remote sensing to detect rising carbon dioxide and sulfur dioxide emissions without endangering people or equipment would greatly increase...
INSIDER: Sensors/Data Acquisition
Researchers have designed and tested a series of plasmonic nanoantenna arrays that could lead to the development of a new generation of ultrasensitive and low-cost fluorescence sensors that could...
Sound-Off: Test & Measurement
Digital Image Correlation (DIC) is a non-contact optical method of measuring deformation and strain on a given material. Measurement accuracy, however, depends on contrast,...

When you arrive back on Earth after a year in space, you’re going to feel it.
NASA and Jacob Bloomberg, senior scientist in the Houston, TX- headquartered Johnson Space...
INSIDER: Sensors/Data Acquisition
Engineers at The University of Texas at Austin have invented the MasSpec Pen that rapidly and accurately identifies cancerous tissue during surgery, delivering results in about 10 seconds — more...
INSIDER: Test & Measurement
Researchers have created a miniaturized, portable version of the mass spectrometer, which traditionally has been bulky, limiting its in-field potential. Other smaller spectrometers have been less...
Briefs: Sensors/Data Acquisition
The Container Screening Device (CSD) is a portable, benchtop measurement system for real-time sealed-container inspection, and content (liquid/ material) classification and discrimination. The technology uses...

Thermal Micro-Extraction Laboratory
Typical extractions in the laboratory require a significant amount of sample material, large-scale equipment, and hands-on participation of a scientist. Such a setup is impractical (or impossible), heavy, and expensive to be carried out on spaceflight instrumentation. While great strides are being made to improve...
Briefs: Test & Measurement
Handheld Device with Reagents for Detection and Diagnostics
The high risk associated with biological threat agents determines that any suspicious sample be handled under strict surety and safety controls, and processed under high-level containment in specialized laboratories. These specialized facilities are complex, very expensive to operate, and...
Briefs: Test & Measurement
Overspeed Protection for Turbine Flowmeters in Cryogenic Applications
Flowmeters for cryogenic applications often fail in service. Turbine flowmeters in particular fail due to very high speeds encountered during chill-down operations. Very cold, very high-velocity gas causes the turbine to spin uncontrollably, which quickly degrades bearings. Those...
Briefs: Test & Measurement
An arson investigation typically requires collecting one or two liters of ashes and debris from various locations within a fire scene in metal cans similar to those used for paint, and sending...
Articles: Energy
Sensors have a key role in industrial production. For example, they can be used for quality and process monitoring or condition-based maintenance. The range of applications is...
INSIDER: Sensors/Data Acquisition
Sprayed sensors were developed that can be networked to render real-time information on the health status of a structure, detecting hidden flaws. The sprayed nanocomposite sensors and an...
INSIDER: Sensors/Data Acquisition
A highly sensitive, soft, capacitive sensor made of silicone and fabric that moves and flexes with the human body can unobtrusively and accurately detect movement. The technology consists...
Products: Test & Measurement
Tektronix, Beaverton, OR, introduced the TTR500 Series USB vector network analyzer, a USB-based RF test instrument. It includes VectorVu-PC analysis software and built-in bias tee for testing active devices. The 2-port,...

As Advanced Driver Assistance System (ADAS) technology evolves, how do you test autonomous cars that ‘learn from their mistakes?’
R&D: Medical
A small, thin square of an organic plastic that can detect disease markers in breath could soon be the basis of portable, disposable sensor devices. By riddling the thin plastic films with pores,...
Briefs: Test & Measurement
Borrowing concepts from medical diagnostic devices, researchers have created a simple, inexpensive set of handheld tests that can detect the presence of many water- or food-borne...
Briefs: Test & Measurement
When performing machine tool setup and maintenance operations, it is frequently necessary to use a position transducer to “sweep” a surface and establish...
Briefs: Test & Measurement
The dependability of energy storage devices — particularly batteries — is becoming increasingly important to consumers, industry, and the military. As battery technology becomes more complex and users' expectations...
Briefs: Test & Measurement
Devices for manipulating fluids on the microscale have been developed to store, hold, and manipulate small amounts of fluids, and have been applied to the detection of analytes in sample fluids....
Briefs: Sensors/Data Acquisition
The Micro-ring resonator detector can determine the speed of blood flow and the oxygen metabolic rate at the back of the eye. This information could help diagnose such common and debilitating...
Briefs: Test & Measurement
Stennis Space Center has the need to measure the inner wall thickness of cryogenic storage tanks without entering the inner tank of the double-walled vessels. It was proposed that an ultrasonic probe be...
