Common alternative Source of energies
Do you ever heard about conversion of sound
energy to electrical energy?
Example?
Micro Phone
SoundForm of vibrational energy that propagates through all mediums except in vacuum.
Which material will convert
sound energy to electrical?
Piezo electric material
How it works ?When the material is Stressed, the mechanical strainenergy gets converted into electrical energy
What happens when stress is applied?
Do the all piezo electric material will convert sound energy to electrical energy? NOMaterials like quartz, bone, DNA could not able to convert as they are formed
naturally But artificially materials like zinc oxide( commonly known as calamine lotion),
Lithium niobatet etc..,
How Generally current produces?
Methodologies suggested
Method 1: Force (sound)
Method 2:
Sound Heat Electricity
Method 3
Sound Piezo Electric Electricity
How much energy could we produce?
For Each 100 dB we get 0.5V
1000 dB 5 Volts
By this voltage we can easily charge our home applianceslike mobile etc..,
where can we harvest sound ?
every where around us .. IndustriesThermal plantsNuclear plants Explosions
RoadsAuditorium
Conclusion :Sound is not continuous form of energy source and difficult to harvest but with help of piezo electric material it can be over come.
