Acoustic tweezers is a microfluidic device that utilizes ultrasound waves produced by
piezoelectric transducers to gently and precisely position biological samples without damage.
We write about
piezoelectric generators from time to time, like sneakers that can power your gadgets or kinetic - energy harvesting sidewalks or wave - powered speakers that let us communicate with dolphins, all of which generate energy from movement.
The K2 ski company has even toyed with
piezoelectric polymers, which generate an electric charge when twisted.
Conventional materials used to create motion by applying electricity, such
as piezoelectric devices, don't work nearly as well at such high temperatures, so the new system could open up a new area of high - temperature sensors and actuators.
Part of the excitement is that such
flexible piezoelectric crystals would make more sensitive detectors and could improve the resolution of medical devices that use ultrasound.
Using
piezoelectric energy generation technology, a team of researchers led by Zhong Lin Wang, a professor of materials science and engineering at Georgia Tech, has successfully figured out the age - old question: can hamsters on wheels really power up a device?
Cohen and collaborator Huaxiang Fu have developed a computer model that explains the large
piezoelectric response of the lead crystals.
Piezoelectric motors can move the 12 electrodes in small 1 - micrometre increments and will back off when necessary to avoid damaging nerve cells.
Under the plastic hood is a 2.2 - liter, 16 - valve, four - cylinder turbodiesel engine with
piezoelectric fuel injectors.
Many vibration harvesters
contain piezoelectric substances that create an electric voltage when mechanically bent.
The team's newly designed flexible
piezoelectric nanogenerator directly stimulated a living rat's heart using electrical energy converted from the small body movements of the rat.
Ingenious ideas generated by the competition in previous years include
piezoelectric sensors in pavements that convert the vibrations of pedestrians» footsteps into electrical energy, salt - water powered vehicles and bacteria generators that convert food waste in future homes into a source of heat, light and power.
Prospects have become even more appealing after a publication, entitled «Band structure engineering via
piezoelectric fields in strained anisotropic CdSe / CdS nanocrystals,» was published in the journal Nature Communications last July.
As a result, the PVDF - carbon hybrids are the best
piezoelectric composites that have been reported to date in the scientific literature, Voit says.
Whereas lead - based compounds typically have the greatest
piezoelectric potential, the heavy metal has fallen out of favor as device - makers push to eliminate it from all electronics in an attempt to reduce toxic waste.
Both the 362 - hp V6 in the SL 450 and the 449 - hp SL 550 V8 employ ultra-precise tech
like piezoelectric Direct Injection and multispark ignition.
Its advanced six - cylinder engine featuring
piezoelectric direct injection and spray - guided combustion generates 215 kW / 292 hp and returns impressively low fuel consumption figures of 9.1 to 9.3 litres per 100 kilometres (NEDC combined).
I haven't heard of successful implementation of
piezoelectric valve management (no hydraulic), this is now the much anticipated electric vvt and management.
But when too many
thin piezoelectric layers are stacked, the cantilever can become too stiff for bending - mode vibrational harvesting.
A team of University of California scientists is experimenting with an alternative to lead - based compounds in piezoelectric systems
In an adjoining room, Bar - Cohen shows off foot - long impact drills driven by PZT disks that he is building with his JPL colleagues and Cybersonics, Inc., in Erie, Pa. «Inside this cylinder is a stack of

The reason for the triangle shape, they said, is that the shape of the holes can't have mirror symmetry, or else the materials won't
become piezoelectric.
Voit is looking to create a similar effect for his PVDF - carbon fibers, which are far
better piezoelectric materials than nylon and would contract in response to an electric current.
