While we normally see piezo elements being used to output audio, [Veedo] thought that they could be used in a more useful manner. He bought way too many piezo film tabs and decided to use them to ...

A 3D-printed piezoelectric metamaterial uses topology-driven charge transport to locate underwater sound sources from a single compact transducer, replacing bulky hydrophone arrays.

In today's concrete jungle, pavement takes up a lot of space, so we might as well cram some smarts in there. Previously we've seen ground coverings that light up, absorb solar energy, generate ...

Cheap piezo buzzers are everywhere. They’re so cheap that they can be used in novelty birthday cards. Applying an alternating voltage across a piezo crystal makes it expand and contract, and fixing ...

Inside each tile are the piezoelectric elements—thin discs of lead zirconate titanate—along with several solar cells and a lithium battery for storing power generated during the day. Researchers at ...

ROHM has recently established a process for MEMS (micro electro mechanical system) using thin-film piezoelectric elements, and implemented a foundry business that is said to be the first based on the ...

Same Sky has added to its portfolio of disc-shaped piezoelectric elements, with devices from 12 to 35mm in diameter and down to 0.12mm thick. Picking the 12mm x 0.12mm CEB-12012-L100 as an example, it ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...

Murphy’s Law predicts that it takes the first 99% of your time budget to finish the first 99% of a job and the second 99% to get it completed. The history of piezoelectric motors can serve as a good ...

These small and strong materials offer a wide frequency range, suiting a variety of applications and specific design needs without sacrificing performance. Electronic engineers are no strangers to odd ...
