Communications

This electronic pill can relay diagnostic information or release drugs in response to smartphone commands.

Loosely connected disc-shaped “particles” can push and pull one another, moving together to transport objects.

These stickers wirelessly beam health readings to a receiver clipped onto clothing.

A technology uses a combination of WiFi signals and accelerometer technology to track devices in near-real-time.

The reader uses a frequency multiplexer to boost its ability to accurately locate a greater number of RFID tags.

RFID-based devices work in indoor and outdoor lighting conditions and could transmit data for years before they need to be replaced.

A novel approach was developed to improve communications range and allow for covert behavior using a team of robots for future multi-domain operations. Specifically, researchers...

Engineers at the University of Illinois have found a way to redirect misfit light waves to reduce energy loss during optical data transmission. In a study,...

A new wireless transceiver was developed that boosts radio frequencies into 100-gigahertz territory, which is quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications...

A soft and conformable health monitor can broadcast electrocardiogram (ECG), heart rate, respiratory rate, and motion activity data as much as 15 meters to a portable recording...

Today’s cellular networks and Wi-Fi systems rely on microwave radiation to carry data but the demand for more bandwidth is quickly becoming more than microwaves can handle. That has...

Since 1998, almost 2,000 shoebox-sized satellites known as CubeSats have been launched into space. Due to their small frame and the fact that they can be made from off-the-shelf...

A pocket-sized antenna was developed that could enable mobile communication in situations where conventional radios don’t work such as underwater, through the ground, and over very...

Scientists of Karlsruhe Institute of Technology (KIT) and École Poly-technique Fédérale de Lausanne (EPFL) have reported that they achieved the fastest distance measurement attained so...

It has been known since the early 1960s that hexagonal sampling is the optimal sampling approach for isotropically band-limited images, providing a 13.4% improvement in sampling efficiency over...

Researchers developed a wearable, disposable respiration monitor that provides high-fidelity readings on a continuous basis. It's designed to help children with asthma and cystic...

In 2016, UC Berkeley engineers demonstrated the first implanted, ultrasonic, neural dust sensors. Now, taking the next step, the smallest-volume wireless nerve stimulator was developed, called StimDust...

Researchers have created technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints that can be used to...

Accurately measuring semiconductor properties of materials in small volumes helps engineers determine the range of applications for which these materials may be suitable in the...

Aircraft currently fly based on coarse estimations of environment and aircraft state. Real-time measurements are traditionally restricted to laboratory environments (e.g. wind tunnel) due to the size and...

Experimental photonic switches developed at UC Berkeley have shown promise toward the goal of fully optical, high-capacity switching for...

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...
