Linear versus rotary, electric, pneumatic or hydraulic, here’s a look at the basics of the actuator component.

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 ...

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 ...

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 ...

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

The electric spark generated by the piezoelectric effect causes gold atoms to precipitate from the fluids on the quartz surface, forming ideal conditions for further gold accumulation. As the ...

Scientists have unlocked a previously unseen behavior of acoustic waves, opening up new possibilities for cutting-edge ...

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." ...
