Piezo-electric effect:
A thin quartz plate (c) is coated on two opposing sides with a conductive material (a), (b) (see
illustration). If a tensile or compressive load is applied to the array, an electrical voltage "U" i
s
produced between the points (d) and (e). The polarity of the generated voltage depends on the
direction of load (compression/tension).
Reversed piezo-electric effect:
If, however, a voltage is applied to the points (d) and (e), the quartz plate increases or decreases
in length.
Task:
Mechanical vibrations can be converted into electrical oscillations using the piezo-electric effect.
For example, for microphones, knock sensors, pressure sensors.
Electrical oscillations can be converted into mechanical vibrations or motion using the reversed
piezo-electric effect: piezo-electric speakers, actuators.
Both effects are combined in the quartz resonator: If an AC voltage whose frequency is roughly
equal to the mechanical resonant frequency (fundamental or harmonic component) of the quartz
plate is applied to the points (d) and (e), the quartz is stimulated to generate resonant vibrations
which stabilize the frequency of the electrical oscillations. For this reason, quartz resonators are
often used where a high degree of frequency stability is required (e.g. in clock generators
(oscillators) for electronic clocks and microprocessors).
