Researchers have developed a method for using radio signals to create real-time images and videos of hidden and moving objects. The system allows real-time imaging around corners and through walls as well as tracking of fast-moving objects such as millimeter-sized space debris flying at 20,000 miles

Shaping glass is mainly based on processes such as melting, grinding, or etching. These processes are decades old, technologically demanding, energy-intensive, and severely limited in terms of the shapes that can be realized. Researchers have developed a process that makes it possible to form glass

Who The SARS-CoV-2 virus that causes COVID-19 is still a major threat to public health. Wearing a facemask is a step in protecting against infection; the new facemask also diagnoses the wearer with COVID-19. What The button-activated mask is embedded with tiny, disposable sensors that can be fitte

Currently, the dominant method to generate ultrafast laser pulses passively is to use semiconductor saturable absorber mirrors (SESAMs). This type of passive mode locker produces exceptional results but is difficult to fabricate, expensive, and limited in bandwidth. In contrast, a graphene-based sat

Inexpensive and convenient devices such as silicone wristbands can be used to yield quantitative air quality data, which is particularly appealing for periods of susceptibility such as pregnancy. The wristbands, when used as passive samplers, have the ability to bind smaller molecular weight semi-vo

NASA Langley developed an instrument to measure low levels of contamination on curved or irregularly shaped surfaces. The instrument offers unique capabilities such as the ability to identify and quantify contamination and analyze multiple surfaces simultaneously. This information provides an analys

The basics of electrohydraulic valves are easy to understand — they are electrically operated valves that control how hydraulic fluid is sent to actuators. However, to apply electrohydraulic valves for efficient and effective hydraulic systems, designers must consider several factors. This article w

The railway network is the backbone of the transportation system in India, connecting remote villages and towns with metropolitan cities across the country. Recent government initiatives aim to revamp and modernize the entire network by 2030 and the past couple of years have brought many changes to

In 1901, a patent was issued to Ransom E. Olds for the idea of a continuously moving assembly line, which he used to build the first Oldsmobile vehicles. In 1913, Henry Ford improved the concept by adding moving conveyor belts and with these two innovations, the time needed to assemble a car went fr

Eddy current displacement sensors belong to the inductive displacement group of sensors and are well-adapted for industrial applications. Unlike conventional inductive sensors, the measuring principle for eddy current sensors enables measurements on non-ferromagnetic materials (e.g., aluminum) as we

Wireless IoT sensing devices can be placed on, in, or near people, equipment, infrastructure, and our environment. This gives us new tools to address the most urgent challenges of our 21st century world: from climate change, to ensuring clean energy, safe food, and foremost, caring for the health an

To find out about the impact of 5G mobile broadband service on the IoT/IIoT, I interviewed Jai Suri, Vice President, IoT and Blockchain Applications Development, Oracle, and Mike Anderson, Embedded Systems Architect, and consultant in the aerospace industry. I asked them if we are close to bringing

An increase in the number of hazardous gases poses a severe threat to humanity in general and to workers in many industries. These gases could come from natural or man-made sources like chemical industries, petroleum refining, stone, plastic, and food processing. Because of the risk that they leak i

The manufacturing facilities of the future will deploy extremely easy-to-use, safe, flexible, and affordable automation supported by AI and standardized software and hardware interfaces. In several key respects, the transformative technologies required to make all this happen are already here, drive

Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal efficiency than conventional terahertz generators, and is thinner, lighter, and less expensive to produce.

Although measuring the electrical activity of neurons is useful in many disciplines, making durable neural interfacing brain chip implants with negligible adverse effects has proven challenging. Now, Korean scientists have developed a flexible multifunctional neural interface that can not only regis

Stacking extremely thin films of material on top of each other can create new materials with exciting new properties. But the most successful processes for building those stacks can be tedious and imperfect, and not well suited for large-scale production. Now a team led by Stanford Professor Hemamal

Medical sensing technology has taken great strides in recent years, with the development of wearable devices that can track pulse, brain function, biomarkers in sweat, and more. However, there is one big problem with existing wearable pressure sensors: even the slightest amount of pressure, somethin

An inspection technique known as Computed Tomography, or CT, uses X-rays to evaluate an object in three dimensions. That third dimension is a valuable one, and allows a manufacturer to get volumetric data to effectively see inside an object. The CT method reveals the internal details of objects like

In the early days of quarantine, Notre Dame professor and robotics engineer Yasemin Ozkan-Aydin used the time at home to put together robots. Ozkan-Aydin developed collaborative legged systems that maneuver over complex terrain — as a team. To move around on rough terrain and in tight spaces, Ozkan-
