KYOCERA Develops Ultra-Thin, Lightweight 'Piezo Film Speaker' for TVs, PCs, Tablets High audio quality "Smart Sonic Sound" utilized in flat-screen TV for first time KYOTO, Japan--(BUSINESS WIRE ...
In order to obtain a piezoelectric response, the material must first be poled in a large electric field. Poling of the material typically requires an external field of above 30 megavolts per metre (MV/m). Thick films (typically >100 μm) must be heated during the poling process in order to achieve a large piezoelectric response. Thick films are ...
The company's new Smart Sonic Sound device still relies on a piezoelectric actuator, but vibrates against a film to generate as much volume as a regular speaker in a far thinner (under 1.5mm thick ...
Piezoelectric polymers (PVDF, 240 mV-m/N) possess higher piezoelectric stress constants (g 33), an important parameter in sensors, than ceramics (PZT, 11 mV-m/N), which show that they can be better sensors than ceramics. Moreover, piezoelectric polymeric sensors and actuators, due to their processing flexibility, can be readily manufactured ...
Piezo-phototronic effect is a three-way coupling effect of piezoelectric, semiconductor and photonic properties in non-central symmetric semiconductor materials, using the piezoelectric potential (piezopotential) that is generated by applying a strain to a semiconductor with piezoelectricity to control the carrier generation, transport, separation and/or recombination at metal–semiconductor ...
Beyoncé and Jay-Z were not listed as expected guests for the premiere of the film, which arrives in theaters Dec. 20. Other "Mufasa" stars spotted on the red carpet were Aaron Pierre ...
In Pin Point PFM, the AFM tip does not contact the surface. The tip is halted at a height at which a predefined force threshold (a threshold at which piezoelectric response is optimal) is reached. At this height, the piezoelectric response is recorded before moving to the next point. In Pin Point mode, tip wear off is reduced significantly.
Keira Knightley admitted in a new interview with the Los Angeles Times that she told “Love Actually” director Richard Curtis while filming the infamous cue card scene with Andrew Lincoln that ...
