Latest Piezoelectricity Stories
In recent years, with the growing concerns over environmental protection and human health, environment-friendly materials have received increasing attention, and for decades researchers have been fiercely studying lead-free piezoelectric materials with high piezoelectric properties.
A special foil sensor developed to measure the pressure on a spaceplane’s wings during reentry into Earth’s atmosphere is now helping to build safer cars.
A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves.
Scientists working as part of the Metrology for Energy Harvesting Project have developed a new model to deliver the maximum power output for piezoelectric energy harvesters.
Though pacemakers require only small amounts of energy (about 1 millionth of a Watt), their batteries have to be replaced periodically, which means multiple surgeries for patients.
Just 100 nanometers in diameter, nanowires are often considered one-dimensional.
Graphene, the ultra-durable carbon material that holds promise for a range of applications, has yet another trick up its single-atom-thick sleeve.
Research conducted at the University of Michigan College of Engineering may lead to the use of insects to monitor hazardous situations before sending in humans.
Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, University of Wisconsin-Madison engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.
Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light.
