Based on the principle of energy conversions, these piezoelectric generators deliver many advantages in multiple applications and industries. As piezoelectricity moves with the concept of conversion of energy from one form to another, generators also work on the same. But, what does a combination of piezoelectricity and generator delivers?
Many of the current piezoelectric energy harvesters have been able to generate power in the order of mW. However, it may not be continuous, and the current output is generally low, thereby limiting the power output.
According to the derived theoretical model, the performance of the piezoelectric energy harvesting is related to a few groups of parameters, comprising of materials, structures, excitations, electrical load, frequency/speed, and time.
A piezoelectric sensor is made up of piezoelectric material (quartz-most used). It used to convert the mechanical stress into electrical charge. The output of the Piezoelectric Sensor is AC. We need a full bridge rectifier to convert it into DC.
By using effective piezoelectric elements. To position the piezoelectric material correctly where it will be hard-pressed very swiftly. For example, when a piezoelectric material holds the ability to enhance the voltage across the capacitor by 2 – 12 V, then the generated energy will be approximately 0.0154 joules.
