Will air pressure induce a voltage of a piezoelectric crystal or does it need to be mechanically compressed? My guess is that it would depend on the permeability of the crystal
A piezoelectric crystal is a type of crystal that can generate an electric charge when mechanical stress or pressure is applied to it. This is known as the piezoelectric effect. When the crystal is compressed or stretched, the arrangement of its atoms changes, creating an electric charge.
Piezoelectric crystals are commonly used in various electronic devices, such as sensors, actuators, and transducers. They are also used in medical equipment, such as ultrasound machines, and in industrial applications, such as precision control and monitoring systems.
Air pressure can affect piezoelectric crystals by exerting a force on them, causing them to deform and produce an electric charge. Changes in air pressure can also alter the sensitivity and accuracy of piezoelectric sensors and transducers.
No, piezoelectric crystals require an external mechanical force to produce an electric charge. However, changes in air pressure can indirectly affect the crystal by causing it to vibrate or deform, which then generates an electric charge.
Piezoelectric crystals have several advantages over other types of pressure sensors, such as their high sensitivity, fast response time, and durability. They can also operate in a wide range of temperatures and are not affected by electromagnetic interference.
