The piezoelectric effect is simple in its rules: Apply mechanical stress to a material and you generate an electric charge. The inverse is also true: Apply a voltage to a material, and it changes ...

While most multiferroics can't operate above room temperature, a team of researchers at Tohoku University demonstrated that ...

The piezoelectric effect arises from the asymmetric arrangement of atoms in certain crystalline materials. When a piezoelectric crystal is subjected to mechanical stress, the deformation of the ...

Multiferroic materials, which have the special ability to connect magnetism and electricity, are now one step closer to ...

Researchers are breaking limits by increasing the temperature multiferroics can operate at, from room temperature up to a blistering 160 degrees Celsius.

Prof. Ryu explains, "Our study explains the materials and device fabrication strategies for tactile sensors using piezoelectric and triboelectric effects, as well as the types of sensory recognition." ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication technologies using acoustic devices.

Piezoelectric effects have been produced in a number of soft tissues, as well as hard, and appear to be associated with the presence of oriented fibrous proteins such as collagen. Thus ...
