Stable power supply thanks to wind turbines
Wind turbines can help keep the voltage in the electricity network at a constant level. The power electronics in the turbines can effectively correct peaks and dips in the mains voltage. This is the conclusion reached by NWO-funded researchers. Modern wind turbines are a good means of coping with fluctuations in the mains voltage. Such... view more... (2001-10-08)
Team develops energy-efficient microchip
Researchers at MIT and Texas Instruments have unveiled a new chip design for portable electronics that can be up to 10 times more energy-efficient than present technology. The design could lead to cell phones, implantable medical devices and sensors that last far longer when running from a battery. view more (2008-02-05)
Bacterial toxin closes gate on immune response, Penn researchers discover
Researchers at the University of Pennsylvania School of Medicine have demonstrated that a bacterial toxin from the common bacterium Staphylococcus aureus shuts down the control mechanism of the tunnel, called an ion channel, in immune cell membranes. view more (2008-02-14)
Sensor of plastic can be produced in a printing press
Electrochemical transistors made of plastic open myriad possibilities. Since both electrons and ions are active, they can function as a bridge between traditional electronics and biological systems. A new dissertation from Linköping University in Sweden describes a simple and inexpensive humidity sensor that can be manufactured in a printing... view more... (2005-02-08)
Gatekeeping: Penn researchers find new way to open ion channels in cell membranes
Using an enzyme found in the venom of the brown recluse spider, researchers at the University of Pennsylvania School of Medicine have discovered a new way to open molecular pores, called ion channels, in the membrane of cells. view more (2006-07-18)
Nanowire generates power by harvesting energy from the environment
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment. view more (2007-09-28)
ANALYTICA 2004: Infrared Sensor is Kind to Costs and Environment
The IMM Institut für Mikrotechnik Mainz GmbH has developed an infrared sensor for the quality control of lubricants in machines. With this sensor, oil and its ageing can be monitored directly at the operating machine. Future fields of application are for example real-time monitoring of large motors, particularly in shipping or compressors.... view more... (2004-05-10)
Multimode Magnetic Field and Position Sensor from Oxford University
Researchers at Oxford University's Physics Department have developed an extraordinarily versatile proximity sensor for the detection of objects, composed of ferrous and non-ferrous metals, ceramics, glasses and plastics. This new device could be used as a position or speed sensor in automotive suspension, gearbox and engine management systems,... view more... (2002-08-14)
Nano-layer of ruthenium stabilizes magnetic sensors
A layer of ruthenium just a few atoms thick can be used to fine-tune the sensitivity and enhance the reliability of magnetic sensors, tests at the National Institute of Standards and Technology (NIST) show. view more (2007-08-06)
NIST/CSM sensor could help avert pipeline failures
Researchers at the National Institute of Standards and Technology (NIST) and Colorado School of Mines (CSM) have developed a prototype sensor that quickly detects very small amounts of hydrogen accumulation in coated pipeline steel. view more (2008-10-03)
New sensor provides simpler measurement of eye pressure
On Friday, May 31, Anders Eklund, Department of Radiation Sciences, Medical Technology, Ume'å University, Sweden, will defend his dissertation evaluating a new and simpler instrument for measuring the pressure of eye fluids, a key risk factor in glaucoma. Anders Eklund has a master's in engineering and works at the Unit for Medical... view more... (2002-05-28)
Measuring electrical arcs at the micrometer scale
Air is a great insulator-except when it becomes a conductor. Under the right conditions, miniature lightning bolts of electricity will "arc" through the air between two electrically conducting points. view more (2006-03-31)
'NMR on a chip' features NIST magnetic mini-sensor
A super-sensitive mini-sensor developed at the National Institute of Standards and Technology (NIST) can detect nuclear magnetic resonance (NMR) in tiny samples of fluids flowing through a novel microchip. view more (2008-02-20)
Tyre sensor will increase driver safety / caesar Research Center at the Hanover Fair
You break on black ice or on a wet highway, friction is almost zero and your car goes into a skid: A scenario which will be avoided in future. Scientists at the caesar Research Center in Bonn are developing a new technology for improving vehicle safety still further. At the Hanover Fair caesar will be presenting from April 7 to 12, 2003, on the... view more... (2003-04-02)
Turfgrass quality measurement improved with GreenSeeker sensor
To measure turfgrass performance, professionals have traditionally relied on trained human evaluators who provide visual assessments of turf quality. view more (2009-09-09)
Maximum Comfort for Patients
A multiple-parameter medical network with wireless sensors for the measurement of vital body functions will be exhibited by Fraunhofer Institute for Integrated Circuits IIS at the CeBIT 2004. It is comfortable and convenient to wear - the wireless sensor wristband of Fraunhofer IIS for the measurement of the pulse waves and the oxygen saturation... view more... (2004-03-05)
Electric Nudge toward Self-organization
In search of materials with nonlinear optical properties Window panes and eyeglass lenses that get darker as it gets brighter are especially great in the summer. Their secret lies in optical properties that change as the light intensity changes - nonlinear optical properties. Such materials are also of interest as optoelectronic components. One... view more... (2002-03-07)
