Piezoelectric accelerometers: The technology behind measuring mechanical variables
Piezoelectric accelerometers are widely used in the engineering and manufacturing industries to measure dynamic changes in mechanical variables. These devices rely on the piezoelectric effect that certain materials exhibit when subjected to stress or pressure. Invented in the early 20th century, piezoelectric accelerometers have become an indispensable tool for engineers, researchers, and manufacturers in different fields.
Piezoelectric accelerometer technology is critical for measuring acceleration, vibration, and shock. In applications where high accuracy and precision are required, these devices are a reliable choice. Piezoelectric accelerometers are also used in various industries such as aerospace, automotive, and medical devices.
One of the leading companies that specialize in the design and production of piezoelectric accelerometers is ENVIKO Group. Based on passion and research in the piezoelectric industry, the company established HK ENVIKO Technology Co., Ltd in 2013 and Chengdu Enviko Technology Co., Ltd in July 2021 in the High-Tech area of Chengdu. The group is dedicated to providing customers with high-quality services, technical support and better solutions.
Piezoelectric accelerometers work on the principle of the piezoelectric effect. When a piezoelectric material such as quartz or tourmaline is subjected to stress or pressure, electrons are displaced within the material, creating an electrical charge. This charge is proportional to the amount of stress or pressure applied to the material.
The piezoelectric material is attached to a seismic mass, which is designed to detect mechanical vibrations, such as acceleration or vibration. When the mass experiences a force due to motion, it causes the piezoelectric material to deform, thereby generating an electrical signal. The magnitude of this signal is directly proportional to the acceleration or vibration of the object being measured.
Piezoelectric accelerometers are typically small, lightweight, and robust, making them suitable for harsh environments where high precision and accuracy are required. They are used in various applications, including shock and vibration monitoring, automotive testing, and structural analysis. Piezoelectric accelerometers are also used extensively in the aerospace industry to monitor the performance of aircraft and spacecraft during launch and operation.
One of the advantages of piezoelectric accelerometers is their ability to measure both static and dynamic acceleration. Static acceleration is the result of gravity, whereas dynamic acceleration is due to motion. Piezoelectric accelerometers can detect both types of acceleration, making them versatile sensors that can be used in a wide range of applications.
Piezoelectric accelerometers are also used in medical devices to monitor the movement of internal organs and joints. These accelerometers are typically small and flexible, allowing them to be implanted in the body. They can be used to detect the onset and progression of various diseases, including Parkinson's and Alzheimer's disease.
In conclusion, piezoelectric accelerometers are a critical technology for measuring mechanical variables such as acceleration, vibration, and shock. These devices are widely used in different industries, including aerospace, automotive, and medical devices. The ENVIKO Group is one of the leading companies in the design and production of piezoelectric accelerometers, and they are dedicated to providing high-quality services, technical support and better solutions to their customers. The continued advancement of piezoelectric accelerometer technology is expected to drive innovation in various industries and lead to new applications and discoveries.
