Energy-Harvesting Design Aims to Turn Wi-Fi Signals Into Useable Power

Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as "T-rays," are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

New Sensor Could Help Prevent Food Waste

As flowers bloom and fruits ripen, they emit a colorless, sweet-smelling gas called ethylene. Chemists have now created a tiny sensor that can detect this gas in concentrations as low as 15 parts per billion, which they believe could be useful in preventing food spoilage.

Deep Learning for Mechanical Property Evaluation

A standard method for testing some of the mechanical properties of materials is to poke them with a sharp point. This "indentation technique" can provide detailed measurements of how the material responds to the point's force, as a function of its penetration depth.

Army Scientists Develop Cutting-Edge, Durable 3D Printing Technology

Army scientists are on the brink of a pioneering additive-manufacturing technology to help soldiers quickly swap out broken plastic components with durable 3D printed replacements, says a top Army researcher.

Brilliant Sole

Brilliant Sole have developed smart insole products for applications including VR tracking, sports performance and medical monitoring. IDTechEx interviewed them at CES 2020.

SEMI-FlexTech Launches Six New Projects

SEMI-FlexTech announced the launch of six projects to accelerate sensor and sensor system innovations for new applications in industries including healthcare, automotive, industrial and defense.

Vionx Energy

Vionx Energy is a Vanadium Redox Flow battery producer, based in Worburn (MA), with focus on high-power/ high-energy flow battery for grid applications.

Finalists Announced for 2019 R&D 100 Awards

Finalists for the venerable R&D 100 Awards have been announced by R&D World magazine and its new parent company, WTWH Media, LLC.

Material for Safer Football Helmets May Reduce Head Injuries

Scientists have developed elastic microlattice pads that can withstand both single hits and a series of impacts better than existing state-of-the-art foams used in football helmets. Their research suggests that the material may pave the way for helmets that better protect football players and other athletes from brain injuries caused by repeated head hits.

XOnano Smartfoam

XOnano Smartfoam produce several additives for foams which enable sensing technologies or enhanced thermal properties. XOnano are a small company but with some key partnerships and rapidly increasing sales are hoping to grow in the coming years.

Epidermal VR Gives Technology a Human Touch

Imagine holding hands with a loved one on the other side of the world. Or feeling a pat on the back from a teammate in the online game "Fortnite."

Race for 1000 km Electric Vehicles

Range sells electric cars. Long range ones sell in 100 times the numbers and have three times the resale value. In this article Dr Peter Harrop discusses the future of electric vehicles capable of 1000km range.

Patrol boat created in 72 hours by 3D printer

The new 3D printer is designed to print objects as long as 100 feet by 22 feet wide by 10 feet high, and can print at 500 pounds per hour. The one-of-a-kind printer will support several ambitious initiatives, including development of biobased feedstocks using cellulose derived from wood resources, and rapid prototyping of civilian, defense and infrastructure applications.

Army researchers test human-like robots

Army researchers tested ground robots performing military-style exercises, much like Soldier counterparts, at a robotics testing site in Pennsylvania recently as part of a 10-year research project designed to push the research boundaries in robotics and autonomy.

Shape-shifting robots built from 'smarticles'

Building conventional robots typically requires carefully combining components like motors, batteries, actuators, body segments, legs and wheels. Now, researchers have taken a new approach, building a robot entirely from smaller robots known as "smarticles" to unlock the principles of a potentially new locomotion technique.

Study identifies main culprit behind lithium metal battery failure

A research team has discovered the root cause of why lithium metal batteries fail—bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access.

US Army wants world's largest, fastest metal powder 3D printer

This printer will revolutionize key supply chains associated with long-range munitions, next-generation combat vehicles, helicopters, and air and missile defense capabilities.
