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)
Researchers putting a freeze on oscillator vibrations
University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill. view more (2009-06-18)
Keeping an eye on fatigue in wind turbines
Wind farms are springing up everywhere like mushrooms. Business in this alternative sector of the energy industry is booming, thanks in part to federal and former state subsidies. The total output of the wind turbines installed in Germany today is theoretically enough to supply the whole capital of Berlin with electricity. But the durability of... view more... (2003-09-18)
New mechanical heart implanted at the MUHC
Surgeons at the MUHC have successfully implanted a new kind of mechanical heart in two patients, the first time this new technology has been used in Canada. view more (2005-11-01)
Remarkable new clothing may someday power your iPod
Nanotechnology researchers at the Georgia Institute of Technology are developing a shirt that harvests energy from the wearer's physical motion and converts it into electricity for powering small electronic devices worn by soldiers in the field, hikers and other users. view more (2008-02-14)
'Suction climbing' and Vertical Cycling at TU Delft
Invitation to the final of the design contest at Mechanical Engineering 'Suction climbing' and Vertical Cycling at TU Delft Students that climb along walls and ceilings like geckos, or that ride a bike up a cable. This can be seen at TU Delft on 7 June 2002, during the annual design contest at the Faculty of Mechanical Engineering. "At this... view more... (2002-06-04)
A CAR THAT RUNS ON FRESH AIR - ALMOST!
Karl's car finished 38th in a field of 109 entrants - an impressive feat by any standards. 'I built the car over a year as an A level technology project,' says Karl. 'The project was sponsored by Marine Projects at Lee Mill in Plymouth and the team consisted of myself and a friend, Sam Starmore, who drove the car for me.' view more (1999-02-01)
Energy network launches international web survey
A European website designed to stimulate informed debate on future energy sources this week launches a multi-lingual survey to gauge public attitudes to, and knowledge of, crucial energy issues. The INTUSER website (www.intuser.net) is a new on-line forum for both the general public and energy experts to communicate about energy issues - from... view more... (2002-12-04)
Optimising the control of wind generators by means of intelligent microsensors
The School of Engineering at Bayonne (ESTIA) is working on a research project on control optimisation for the latest-generation wind generators using intelligent microsensors. view more (2006-04-25)
Manufacturing inefficiency
Modern manufacturing methods are spectacularly inefficient in their use of energy and materials, according to a detailed MIT analysis of the energy use of 20 major manufacturing processes. view more (2009-03-30)
A giant wind-powered generator
The new TWT-1650 wind-powered generator presented in Pamplona has 36-metre vanes which, in a circular movement, sweep an area greater than that of a football pitch and which can withstand extremes of weather, including winds of up to 110 kilometres an hour. This device, made by Grupo Mtorres in collaboration with the Institute for the... view more... (2003-10-14)
Quantum analog of Ulam's conjecture can guide molecules, reactions
Like navigating spacecraft through the solar system by means of gravity and small propulsive bursts, researchers can guide atoms, molecules and chemical reactions by utilizing the forces that bind nuclei and electrons into molecules (analogous to gravity) and by using light for propulsion. view more (2007-08-08)
Disorder enables extreme sensitivity in piezoelectric materials
A research team working at the National Institute of Standards and Technology (NIST) has found an explanation for the extreme sensitivity to mechanical pressure or voltage of a special class of solid materials called relaxors. view more (2008-05-19)
Harrowing bowel preparation is unnecessary before colorectal surgery
Research news from The Cochrane Library Surgeons and other experts have long regarded mechanical bowel preparation to be an essential preventative measure before colorectal surgery. Recent evidence in The Cochrane Library, however, reveals that mechanical bowel cleansing does not significantly decrease the risk of anastomotic leakage or other... view more... (2003-10-20)
Mechanics: Ordinary meets quantum
At the quantum level, the atoms that make up matter and the photons that make up light behave in a number of seemingly bizarre ways. view more (2009-06-22)
Bridging the gap - mechanical support could increase survival of children requiring heart transplantation (pp 1948, 1967)
Embargoed 0001 h (London time) 12 December 2003. Fewer children should die while waiting for a heart transplant if they are given mechanical heart support before transplantation, conclude authors of a UK study in this week's issue of THE LANCET. Short-term mechanical heart support has potential for aiding children requiring heart transplantation.... view more... (2003-12-10)
"Heftier" Atoms Reduce Friction at the Nanoscale, Study Led By Penn Researcher Reveals
A research team led by a University of Pennsylvania mechanical engineer has discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by changing the mass of the atoms at the surface. view more (2007-11-02)
Kansas State engineer focuses on the mechanics of better bullet proofing
Body armor with greater ballistics resistance is the aim of the research being carried out by Youqi Wang, associate professor of mechanical engineering at Kansas State University, with support from two U.S. Department of Defense agencies. view more (2006-11-21)
See the force: Mechanical stress leads to self-sensing in solid polymers
Parachute cords, climbing ropes, and smart coatings for bridges that change color when overstressed are several possible uses for force-sensitive polymers being developed by researchers at the University of Illinois. view more (2009-05-07)
