Anew electromyography biofeedback device that is wearable and connects to novel smartphone games may offer people with incomplete paraplegia a more affordable, self-controllable therapy to enhance...

Light is widely used for communications, carrying phone conversations and video signals through fiber optic cables around the world in pulses composed of many photons. Single...

Silicon is a naturally occurring material commonly used as a semiconductor in electronic devices; however, researchers have exhausted the potential of devices with semiconductors made...

An interdisciplinary Northwestern University team has developed a pair of soft, flexible wireless sensors that replace the tangle of wire-based sensors that currently monitor babies in hospitals’...

A current-steering digital-to-analog converter (DAC) was developed that achieves improved switching times (up to 75% faster) in high-speed (gigahertz), high-resolution (8-14...

Ordinary WiFi can easily detect weapons, bombs, and explosive chemicals in bags at museums, stadiums, theme parks, schools, and other public venues using a low-cost suspicious...

Emergency situations such as trying to escape heavy smoke from fire could leave the sense of touch as the only way to find an exit. Rather than trying to look at a smartphone screen, a...

The traditional approach for wireless sensors involves interrogators that communicate with each other (i.e., the two boxes “talk” to each other). In contrast, surface acoustic wave...

GPS signals do not penetrate very deeply or at all in water, soil, or building walls, and therefore can’t be used by submarines or in underground activities such as surveying mines. GPS also...

Innovators at NASA’s Glenn Research Center have developed a hybrid telescope antenna system — Teletenna — to deliver high-data-rate communication over great distances. Teletenna has...

Many devices use light to probe the quantum states of atoms in a vapor confined in a small cell. Atoms can be highly sensitive to external conditions, and therefore make superb detectors....

Sponsored by the Office of Naval Research's (ONR) TechSolutions program, the Flashing Light to Text Converter (FLTC) features a camera that can be mounted atop a signal...

Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging, and Light Detection and Ranging (LIDAR) systems. In the...

Future Unmanned Aerial Systems (UAS) and air taxis will require advanced onboard autonomy to operate safely within complex and dynamic urban environments. Urban landscapes...

Objects in our daily lives, such as speakers, refrigerators, and even cars, are becoming “smarter” day by day as they connect to the Internet and exchange data, creating the Internet of Things (IoT)....

Outsourcing machine learning is a rising trend in industry. Major tech firms have launched cloud platforms that conduct computation-heavy tasks, such as running data through a convolutional...

Government infrastructure facilities such as water treatment facilities, power plants, laboratories, and the like may be targets for terrorist attacks. Similarly, oil pipelines, power grids,...

Pointing precision is a critical element of instrumentation for optical communications and ranging in space, affecting laser design, link power budgets, and SWaP. While star trackers possess...

Hundreds of small robots can work in a team to create biology-inspired shapes without an underlying master plan, purely based on local communication and movement. To achieve this, the biological...

In traditional hardwired avionics systems, sensor integration requires installation of literally tons of physical cable that significantly increases vehicle weight and the...

Infrared motion detectors can cover only a limited amount of space, a person has to be within the detector's line of sight to be detected, and lights can go off when a person remains...

Printable metal tags have been developed that could be attached to everyday objects to turn them into “smart” Internet of Things (IoT) devices. The tags are made from...
