Advantages and disadvantages of piezo?

Advantages:They generate a voltage proportional to the velocity the crystal is deformed so require no local power source.

Disadvantages: They are high impedence and can pick up stray voltages in the connecting wires. The crystal is also prone to cracking if overstressed.


A piezoelectric crystal transducer is an active sensor and it does not need the help of an external power as it is self-generating. It is important to know the basics of a piezoelectric quartz crystal and piezoelectric effect before going into details about the transducer.


How to Measure Piezo Transducer Efficiency?

One way to measure the efficiency of a transducer is to compare the amount of input energy versus output energy. Anytime energy conversion occurs, some amount of energy will be lost during the process. In general, the greater the amount of output energy produced in relation to input energy, the greater the level of efficiency that is present.
