Definitions
- the layers of piezoelectric material thereof are remarkably durable, or solid, despite their reduced thickness. (and usually the presence of a hole in their center).
- the cables 14 allow the power supply of the piezoelectric assembly. Under the effect of this bias, the piezoelectric assembly 1 reacts by piezoelectric effect and generates ultrasonic vibrations. These are communicated to the sonotrode 2 and propagate essentially towards the front of the system.
