T he circuit in Figure 1 solves the problem using a cross-coupled configuration. The operation is as follows: The microcontroller turns Q 2 on and Q 4 off by applying high- and low-logic-level ...

Piezoelectric Fibers. Article by Erica K. Brockmeier Portrait by Kathy F. Atkinson; all others submitted by researchers May 06, 2024. UD engineers are the lead inventors on a new patent for making ...

However, until now, this process was not viable for piezoelectric thin films. This is because applying a voltage to the substrate does not only accelerate the film‑forming target ions, but also ...

It turns out that quartz is the only abundant mineral that's piezoelectric, meaning that it generates a charge when it's placed under strain. While you don't need to understand why that's the case ...

But one Swiss startup says it has developed a piezoelectric catalyst that can eliminate 99 percent of these forever chemicals in wastewater streams and prevent them from entering water supplies.

A pair of chemists at Michigan State University has observed the piezoelectric effect in liquids for the first time. In their paper published in The Journal of Physical Chemistry Letters, Md ...

What Are Piezoelectric Crystals And How Do They Work? We’ve found a lot of ways to make use of this strange property of certain crystals, but the most important effects were here long before us.

Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent ...

Other characteristics that made piezoelectric materials appealing in a variety of applications include their low cost, lightweight nature, as well as being easy to be controlled and modelled in ...
