FIND MORE INFORMATION ABOUT PIEZOELECTRIC SENSOR

Based on this research i can more information about piezoelectric sensor. for this link http://www.explainthatstuff.com/piezoelectricity.html i get a new information about piezoelectric sensor. How the Piezoelectric sensor works which mean how the piezoelectric sensor can produce from mechanical energy convert to electrical energy.

For this time i will simplify the process of piezo sensor works:

1. Normally, the charges in a piezoelectric are exactly balanced, even if they are not symmentrically arranged.

2. The effect of the charges exactly cancel out, leaving no net charge on the crystal faces. ( more specifically, the electricity dipole moment- vector line separating opposite charges- exactly cancel one another out.) 

3. if squeeze the crystal, the force will charges out of balance.

4. The effect of the charge ( their dipole moment) no longer cancel one another out and net positive and negative charge appear on opposite. 

5. So by the squeezing the sensor , it will be produce a voltage across its opposite faces. And that is called PIEZOELECTRICITY.

GENERATION OF IDEA BASED ON LITERATURE REVIEW

GENERATION OF IDEA

Based on all of journal that has found, it has some of info to use on this project. As example, for first journal is application of piezoelectric sensor and concept of piezoelectric sensor which is to convert mechanical energy to electrical energy. Other than that, piezo impact created is because of the adjustment in the electric polarization of the materials due to the apply stress which prompts the production of electric current or voltage. Next for second journal is for piezoelectric sensor have two type of effect which is direct piezoelectric effect and converse piezoelectric effect. Direct piezoelectric effect is the generation of electric charge when mechanical strain is applied on piezoelectric materials; whereas the converse effect is defined as the deformation in the crystal caused, when an electrical voltage is applied to the piezoelectric materials. Next journal is known about requirement for a wireless electrical power supply has impelled  an enthusiasm for piezoelectric energy collecting. So, all journal give a more knowledge and can apply on this project.
