The piezoelectric effect plays a vital role in many areas of modern technology, especially in sensors, actuators, and energy harvesting devices. Piezoelectric tubes are a special type of piezoelectric material that can generate voltage when mechanical stress is applied or deform under the action of an electric field.
This property is derived from the crystal structure and charge distribution of piezoelectric materials, which can effectively convert mechanical energy into electrical energy and vice versa. This article will explore the working principle of piezoelectric tubes in depth and reveal how they can play an important role in various applications using the piezoelectric effect.
The piezoelectric effect is the generation of electrical energy in certain piezoelectric materials when mechanical forces are applied. This occurs when the centers of positive and negative charges in the material shift, creating an electric field within the material. When piezoelectric materials are stretched or compressed, their charge balance is disturbed, such that one side of the material becomes negatively charged and the other positively charged when the applied force changes the charge balance by 10%.
The effect was first discovered in 1880 by French physicists Jacques and Pierre Curie, who noticed that certain crystalline minerals, such as quartz and tourmaline, became electrically polarized when mechanically stressed. This discovery led to the exploration of the potential of piezoelectric materials, particularly for sonar applications. Piezoelectric devices were first used to detect icebergs in the early 20th century, sparking widespread interest in the technology.
In addition, the inverse piezoelectric effect has been demonstrated, whereby piezoelectric materials, when exposed to an electric field, stretch or shorten depending on the polarity of the field, and the degree of deformation is proportional to the strength of the field.
The combination of these phenomena has led to the widespread use of piezoelectric materials in fields such as sensors and actuators. Although the voltages and motion amplitudes they generate are generally small, they still show amazing application potential, including the development of force or displacement sensors.
The piezoelectric effect has a wide range of applications in various fields, ranging from consumer electronics to medical devices. For example, in inkjet printing technology, piezoelectric materials are used to convert electrical signals into precise control of inkjet nozzles, thereby achieving high-quality image printing. In terms of sound detection and generation, smartphones use piezoelectric technology to convert the user's voice energy into electrical signals, transmit them to another phone and convert them into recognizable sounds.
In addition, piezoelectric technology is also used for electronic frequency generation, high voltage generation, and ultra-fine focusing of optical components. It can drive ultrasonic nozzles and microbalances, showing its advantages in precision control and measurement. Due to its extremely wide range of applications, the piezoelectric effect is widely used in various industries. For example, it is used in keyless entry devices, smoke alarms, patient monitors, airbag sensors, and fish and depth detectors.
The inverse piezoelectric effect plays a role in driving applications, such as motors and devices for precise positioning control, and generating sound and ultrasonic signals. As piezoelectric materials were further studied in the 20th century, the emergence of piezoelectric ceramics based on metal oxides and other artificial materials enabled designers to employ the piezoelectric effect and the inverse piezoelectric effect in many new applications. These piezoelectric materials are generally physically strong and chemically inert, and are relatively inexpensive to manufacture.
In particular, piezoelectric ceramics made from lead zirconate and lead titanate formulations are the most widely used piezoelectric ceramics today due to their higher sensitivity and operating temperature. The composition, shape, and size of this material can be customized to meet the requirements of a specific application, further expanding the application potential of piezoelectric technology.
