(Phys.org)—The piezoelectric effect, which causes a material to expand along the direction of an applied electric field, is common in many materials and used in a variety of technologies, from medical ultrasound to vibration-powered ...
Piezoelectricity (aka the piezoelectric effect) occurs within certain materials – crystals (notably quartz), some ceramics, bone, DNA, and a number of proteins – when the application of mechanical stress or vibration ...
(Phys.org) —Piezoelectric materials, which produce electricity in response to mechanical stress, account for a $12 billion global industry that is projected to grow at a rate of 13.2% per year, according to a recent report ...
(Phys.org)—Taking an important step forward for self-powered systems, researchers have built a nanogenerator with an ultrahigh output voltage of 209 V, which is 3.6 times higher than the previous record of 58 V. The nanogenerator, ...
A touch of gold—or another noble metal—can change the structure of a crystal and its intrinsic properties, physicists at the University of Warwick have demonstrated in a display of modern-day alchemy.
