A research team in China has reported a significant piezoelectric effect in ultrathin and ultra-flexible polycrystalline diamond membranes. This pioneering discovery challenges a century-long ...

Diamond has long been regarded as a nonpiezoelectric material. Now, researchers have identified a piezoelectric effect in ultrathin, ultraflexible polycrystalline diamond membranes. Piezoelectric ...

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. Iqbal ...

One of the reasons gold is so valuable is because it is highly unreactive—if you make something out of gold, it keeps its lustrous radiance. Even when you can react it with another material, it’s also ...

The effect: polarisation and electric field are pointing in the same direction. With positive d33, the sample expands, whereas the material is contracting when d33 is negative. Since 2011, it has been ...

Diamond is famous for being one of the hardest materials on Earth. For more than a century, scientists also believed it could ...

Piezoelectric crystals are a class of materials that exhibit a unique property called piezoelectricity. These crystals generate an electrical charge when subjected to mechanical stress or strain, and ...

Polyvinylidene fluoride (PVDF) is a piezoelectric polymer material that has shown great aptitude as a pressure and flow sensor, especially in biomedical applications. However, most of the PVDF thin ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

When mechanical constraints meet electrical performance requirements, the margin between adequate and optimal often determines whether a component succeeds in its intended application. Piezoelectric ...
