ENERGY HARVESTING THROUGH MECHANICAL STRAIN(PEIZOELECRICITY
Can you produce electricity while car driving/ walking ?
Can you imagine that you can produce electricity by your waste mechanical energy?
Your wasted mechanical work can be used to generate the electric power?
Is that possible???????????...........
Answer is yes . How that we are to see. So wait & watch it.
ENERGY HARVESTING THROUGH MECHANICAL STRAIN(PEIZOELECRICITY)
Piezoelectricity is the charge which accumulates in certain solid materials in response to applied mechanical strain.
The word piezoelectricity means electricity resulting from pressure. It is derived from the Greek peizo or peizen, which means to squeeze or press, and electric or electron , which stands for amber – an ancient source of electric charge.
