Materials (Kiia)
Modeling piezoelectric sensing:
As earlier we determined how piezoelectric will work and here is explanation how to determine a g-coefficent:
Determining the coefficent a voltage gradient:
Determining other coefficent which h is determined:
Piezoelectrical phenomenon is said in other words that it changes mechanical energy into electrical energy
It can be determined as the following:
coupling coefficents kmn is:
The capacitance of piezoelectric can be determined by using the formula as below:
where a is area and l is the crystal thickness
At last the output voltage can be calculated such as:
