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 ...
Processed materials are typically in the non-piezoelectric alpha phase. The material must either be stretched or annealed to obtain the piezoelectric beta phase. The exception to this is for PVDF thin films (thickness in the order of micrometres). Residual stresses between thin films and the substrates on which they are processed are great ...
On July 14, 2022, YouTube made a special playlist and video celebrating the 317 music videos to have hit 1 billion views and joined the "Billion Views Club". [ 65 ] [ 66 ] On April 1, 2024, the communications app Discord incorporated a short trailer video into their in-app April Fools' Day prank regarding loot boxes .
The use of thin film piezoelectric materials in electronics began in the early 1960s at Bell Telephone Laboratories/Bell Labs. Earlier piezoelectric crystals were developed and used as resonators in applications like oscillators with frequencies up to 100 MHz. Thinning was applied for increasing the resonance frequency of the crystals.
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 ...
One TikTok trend involves “Get Ready With Me Videos” where employees film themselves getting laid off or fired. If things aren’t handled well by the company, the video can go viral.
The majority of historic actuators are made of ceramic piezoelectric materials. While these materials are able to withstand large forces, they commonly will only deform a fraction of a percent. In the late 1990s, it has been demonstrated that some EAPs can exhibit up to a 380% strain, which is much more than any ceramic actuator. [1]
After hearing the story behind the hat, Leo asked Kapas if he could film a video of it for social media; the clip went viral, amassing more than 31 million views. In the video, Kapas shares the ...
