20X8X4MM Pzt -5 Piezoelectric Ceramic Element Used As Ultrasonic
Sensors
20X8X4MM Pzt-5 Piezoelectric Ceramics Used as Ultrasonic Sensors.
When the voltage acts on the piezoelectric ceramic, it will produce
mechanical deformation with changes in voltage and frequency. On
the other hand, when the piezoelectric ceramic is vibrated, an
electric charge is generated. Using this principle, when an
electric signal is applied to a vibrator consisting of two
piezoelectric ceramics or one piece of piezoelectric ceramic and
one metal piece, so-called bimorph element, ultrasonic waves are
emitted due to bending vibration. In contrast, when an ultrasonic
vibration is applied to a bimorph element, an electrical signal is
generated. Based on the above effects, piezoelectric ceramics can
be used as ultrasonic sensors.
Piezoelectric Ceramics Body
Piezoelectric ceramic chip is a simple and lightweight electrical
device, which has been widely used due to its high sensitivity, no
magnetic field dispersion, no copper wires and magnets, low cost,
low power consumption, and ease of mass production. Suitable for
the transmission and reception of ultrasonic and infrasound waves,
piezoelectric ceramics with large area can also be used to detect
pressure and vibration. The working principle is to use the
reversibility of the piezoelectric effect and apply an audio
voltage to it to emit sound.
