Securing America's power grid
Terrorists attack Colombia's electrical grid hundreds of times a year. What's to stop attacks on America's power lines? view more (2006-06-27)
Making sense of sensors
A forest ranger helicopter flies over a forest, scattering sensors that can relay temperature data to the ranger station. To ensure minimal environmental impact with maximum robustness, the sensors are very simple: they are basically tiny, sturdy thermometers. view more (2006-12-05)
Crop Management: How Small Do We Go?
The use of on-the-go crop and soil sensors has greatly increased the precision with which farmers can manage their crops. Recently released research in Agronomy Journal questions whether more precise management is necessarily more efficient. view more (2008-07-09)
Probably wireless
Wireless Sensor Networks (WSNs) used to detect and report events including hurricanes, earthquakes, and forest fires and for military surveillance and antiterrorist activities are prone to subterfuge. view more (2008-09-04)
Putting the new generation of hi-tech applications to the test
INNOVATIVE entrepreneurs and company bosses wanting to develop the next generation of mobile technology now have the chance to put their ideas to the test at a unique, state-of-the-art facility run by Staffordshire University. Staffordshire University is recognised as a national leader in mobile and wireless technology. Its Faculty of Computing,... view more... (2004-02-11)
UF engineer develops tiny, easily mass-produced motion sensor
A University of Florida engineer is the latest researcher to design a tiny, easy-to-manufacture motion sensor, a development that could help popularize the sensors as standard equipment in personal electronics, medical devices and other applications. view more (2006-02-10)
New reflux disease technology more comfortable, not more effective
A wireless device that measures the acidity of stomach contents backwashed into the esophagus allows patients to avoid some of the nose pain and throat discomfort associated with the conventional wired monitor used to manage hard-to-treat gastroesophageal reflux disease. view more (2006-07-11)
New ultrasensitive electronic sensor array speeds up DNA detection
A novel electronic sensor array for more rapid, accurate and cost-efficient testing of DNA for disease diagnosis and biological research has been developed by scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN). view more (2009-08-27)
Robust sensor yields cleaner car exhaust
Emissions from cars have to be reduced further in order to meet today's environmental demands. A new and robust exhaust sensor developed by researchers at Linköping University in Sweden has proven to meter the consistency of exhaust gases extremely well and is now on its way to the market. view more (2005-04-27)
Boston University partners in NSF challenge to create wireless network using visible light
Boston University's College of Engineering is a partner launching a major program, under a National Science Foundation grant, to develop the next generation of wireless communications technology based on visible light instead of radio waves. view more (2008-10-07)
Tunable Windows To Keep Office Secrets
Secrets that zip across offices through wireless computing networks all too easily also zip through office windows into the hands of competitors - now researchers at the University of Warwick have devised a method of producing tunable surfaces that can selectively block signals from wireless networks from spilling out of the office. view more (2004-12-13)
Disposable sensor uses DNA to detect hazardous uranium ions
Researchers at the University of Illinois at Urbana-Champaign have developed a simple, disposable sensor for detecting hazardous uranium ions, with sensitivity that rivals the performance of much more sophisticated laboratory instruments. view more (2007-02-15)
New non-invasive sensor can detect brainwaves remotely
Scientists have developed a remarkable sensor that can record brainwaves without the need for electrodes to be inserted into the brain or even for them to be placed on the scalp. Conventional electroencephalograms (EEGs) monitor electrical activity in the brain with electrodes placed either on the scalp (involving hair removal and skin abrasion)... view more... (2002-10-24)
I'm forever imploding bubbles
The National Physical Laboratory (NPL) has developed the first sensor capable of measuring localized ultrasonic cavitation - the implosion of bubbles in a liquid when a high frequency sound wave is applied. view more (2009-04-07)
A turbo compressor for mobile surfers
Despite faster Internet connections, many users still resentfully associate the three letters www with "world wide wait". This is also due to the fact that files are constantly increasing in size. When using wireless terminals with low-resolution displays, such as palmtops or PDAs, it is not in fact necessary to transfer all elements of... view more... (2003-02-20)
Analog and digital - hand in hand
Digital and high-frequency analog integrated circuits are manufactured using their own specific processes, leading `separate lives` in the past. Using standard CMOS, both types of component can now be integrated on a single chip - like a wireless transmitter device. view more (2002-02-01)
Smart buildings to guide future first responders
The best response to a building emergency is a fast and informed one. The National Institute of Standards and Technology (NIST) is working with the building industry as well as the public safety and information technology communities to achieve both objectives. view more (2005-11-07)
Smallest Nanoantennas for High-speed Data Networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. view more (2009-10-21)
SCAI highlights study using wireless technology to speed care of heart attack patients
Imagine paramedics mobilizing a team of cardiologists and nurses within minutes of arriving at the home of a person who is having a heart attack, simply by pressing a button that sends an electrocardiogram (ECG) over a wireless network. view more (2007-05-18)
Noise measurement may boost cell phone performance
Researchers at the National Institute of Standards and Technology (NIST) and industry collaborators have developed improved methods for accurately measuring very faint thermal "noise"—caused by random motion of electrons—in electronic circuits. view more (2006-06-28)
