An accelerometer is a device or gear that aids to measures proper acceleration. A piezoelectric accelerometer that uses the piezoelectric effect of certain materials to measure the changes in mechanical variations, for instance, vibration, mechanical shock, and acceleration. The piezoelectricity is the electric charge that accrues in specific solid materials such as crystals, ceramics, and biological entities such as bone, DNA, proteins, etc. in the reaction of applied mechanical stress. Piezoelectric transforms the energy from one form to another form and generates an electrical signal in response to property, quantity, or a condition that is to be computed. By using the general sensing technique which is applicable to all accelerometers, acceleration acts on the basis of seismic mass which is controlled by a spring or suspended on a cantilever beam and transforms a physical force into an electrical motion. Before transforming the acceleration into an electrical quantity, initially, it needs to be converted in either a force or displacement. This transformation is completed through the mass-spring system.
Increasing demand for piezoelectric accelerometers among the aerospace industry due to the necessity of reliability and high accuracy is one of the major aspect fueling the global market growth. In addition, this demand can be attributed to application in various activities carried out in the aerospace industry such as ejection systems, landing gear hydraulics, and rocketry. This is another aspect propelling the piezoelectric accelerometers market.
However, piezoelectric accelerometers can be used only for dynamic measurement and highly sensitive to temperature which may negatively effect on the demand and challenge growth of the global market
The type of piezoelectric accelerometer is divided into PE and IEPE (Integrated Electronics Piezo-Electric). The mechanism of the IEPE sensor (usually employed as FET circuit) transforms the high impedance signal of the piezoelectric substance into a voltage signal with a low impedance of approximately 100 Ω. A low impedance signal is useful due to as it can be transferred across lengthy cables without losing the quality of the signal.
