| 例句 | “Same way I sent you back without me: piezoelectricity. Ever heard of that?” Dragons in a Bag 2018-10-23T00:00:00Z For example, Pierre pressed crystals along their axes to produce an electric charge called piezoelectricity. Books of The Times: Inventing a Graphic Treatment for the Curies 2010-12-21T17:05:40Z But the Japanese team found that exposing them to AC currents—the sort fed to homes and businesses—produced stronger piezoelectricity. Transparent, power-producing crystals could lead to invisible robots, self-powered touch screens 2020-01-15T05:00:00Z Many crystals contain defects whose concentration varies across the crystal; the resulting concentration gradient breaks the macroscopic symmetry of the crystal, causing residual piezoelectricity and pyroelectricity3. Temperature-dependent polarization in a non-polar crystal 2019-11-17T05:00:00Z This approach, producing what is known as piezoelectricity, is often used in loudspeakers and microphones. How the body could power pacemakers and other implantable devices 2018-06-08T04:00:00Z Since 2009, all the displays at the East Japan Railway Company's Tokyo station have been powered by people walking on floor tiles that utilise piezoelectricity. Future Energy: LA crystals turn cars into energy source - BBC News 2017-06-28T04:00:00Z The technology involves piezoelectricity — a form of charge that is created in vibrations of certain crystals and ceramics. Building a Better Battery 2014-02-03T00:22:03Z So she started looking elsewhere and came upon piezoelectricity — a form of charge that is created in certain crystals and ceramics when vibrated. The Idea: An Inventor Wants One Less Wire to Worry About 2013-08-17T18:37:03Z Static or piezoelectricity is another popular candidate for the helicopter halos–as opposed to the pyrophoric, muffler-scraping-on-the-road phenomenon I describe in the video above. The Beautiful Science of Helicopter Halos 2013-08-01T17:45:00.783Z The prototype pacemaker, which is smaller than a penny, runs on piezoelectricity—the electrical charge generated by motion, reports Daily Mail. Pacemaker Prototype Could Be Powered By Heartbeat 2012-11-05T15:21:00Z The device relies on piezoelectricity, a phenomenon where an electrical charge is produced in a material when it is mechanically deformed or stressed. Scientists Harness Human Power for Electricity 2012-06-26T17:45:00.187Z Cigarette lighters and starters on gas grills rely on piezoelectricity. Green Blog: A Virus That Helps Charge Your Cellphone 2012-06-06T12:11:05Z It is known as piezoelectricity, basically an electric charge that accumulates in certain solids, including crystals, bone and some polymers, in response to applied mechanical stress. Paving Slab Generates Electricity with Footfalls 2011-11-14T20:45:00.237Z But engineers are only now beginning to see piezoelectricity as a source of abundant energy. A bounteous source of power may lie right beneath our feet 2010-04-27T04:00:00Z |
