How Does Piezoelectric Transducer Works?

Do you even know what a piezoelectric transducer(https://bit.ly/3gJOmFB) is? It is a sensor or a device that you can use to measure the changes in strain, acceleration, temperature, force, or pressure by converting the energy into electrical energy. It is the device that converts the energy into voltage when you squeeze it or apply any kind of force or pressure on the transducer.
