Manufacturers : Electronic components : Piezoelectric devices
Piezoelectric devices generally consist of a piezoelectric material that deforms when an electric field is applied across it. A piezoelectric device is characterized by generating a force or displacement when a voltage is applied, and generating a voltage when a force is applied, and it has a wide range of application such as various actuators and sensors. Many products make use of piezoelectricity of these piezoelectric materials. Piezoelectricity is the general term to describe the property exhibited by certain crystals of becoming electrically polarized when stress is applied to them. These products include piezoelectric actuators, piezoelectric vibrators in the form of computer oscillators, ceramic filters, piezoelectric transducers, the ignition elements of gas instruments, piezoelectric buzzers, ultrasonic transceivers, microphones, and ultrasonic humidifiers. Small information apparatus, such as HDDs (hard disk drives), mobile computers, and IC cards, and electronic apparatus, such as cellular phones, use a piezoelectric device, such as a piezoelectric vibrator, or a piezoelectric oscillator which includes a piezoelectric vibrating reed contained and sealed in a package. Piezoelectric actuator elements are generally used for volume control, switches, or ink jet droplet control since they expand or contract when a voltage is applied to generate a displacement that is practically proportional to the applied voltage. Piezoelectric resonators are widely used in electric circuits because they are small and light, and more stable in frequency and suffer less change over time than other electric parts. In electronic devices, electronic home appliances, cell phones, and other such electronic devices, piezoelectric electroacoustic transducers have been widely used as a piezoelectric buzzer or piezoelectric receiver for producing an alarm sound or an operating sound.
