15 Innovative Approaches To Improve Your Piezo Discs And Cylinders

Piezoelectric ceramics have piezoelectric properties, ie they exert extra charge when pressure is applied.The piezoelectric effect reflects the coupling between the elastic and dielectric properties of the crystal.Piezoelectric pickup piezo transducer reflects the relationship between elastic variables (stress and strain) and electrical variables (electric field and electrical displacement) of piezoelectric ceramics. Considering piezo level sensor as a thermodynamic system, the piezoelectric equations can be deduced from the thermodynamic eigenfunction describing the state of the system. According to the theory of thermodynamics, for the reversible process, the micro-change of the internal energy of the system can be expressed as follows.For the piezoelectric body, the micro-work piezo electric sensor done by the outside world to the system includes the micro-function elastic and micro- The micro work done by the force is to choose a certain independent variable, and the thermodynamic equation of state can be derived from the internal energy differential equation, so as to obtain the corresponding piezoelectric electrical hifu ultrasound .When the piezoelectric vibrator is applied to a resonant filter, a transducer, a delay line and an acousto-optic device, in order to effectively excite the desired vibration mode, the piezoelectric vibrator of a certain crystal material must be selected to have a specific shape and size.And the mode of excitation, that is, the piezoelectric vibrators of different vibration modes are generally different in shape and boundary conditions, and thus the piezoelectric equations is describing the different piezoelectric vibrators. During the experiment, we should determine the vibration mode of the piezoelectric vibrator according to the specific application of the piezoelectric ceramic, that is, selecting the appropriate boundary conditions of the corresponding piezoelectric shape to establish the equation, cylinder piezo transducer is finding the factors that affect the performance and get the optimal solution. For different boundary conditions for calculation convenience, often choose different independent variables and dependent variables to describe the piezoelectric oscillator piezoelectric equation.
