Does this power generated can be stored in batteries? Application could be in shoes and foot paths in order to harvest energy. I'm working on these applications would like to know all the possible options please.
Electric power generated by piezoelectric material by applying our body weight may vary according to the temperature variation of the crystal. Also developing piezoelectric generators is challenging because of its relatively low output which could not be amplified with minimal footsteps. However on the basis of a thumb rule, for an average human weight of 50kgs, it may take around 500 steps to generate 1V. Implementing foot step power generation in an area with high mobility, 12V or 24V can be generated approximately in a period of 1 hour with suitable battery storage.
Dear Rohith,
Regarding you question, I am attaching to this message a paper that can answer some of your question. You can contact after about this.

Dear Benbouzid,
I would like to know the same scalar V/I mentioned in the pdf shared would play a major role here too.
I'm not clear on how much mechanical energy would be converted to electrical (efficiency) for piezoelectric material. What would be the maximum conversion for a given area. Also can this efficiency be improved?
As far as magnetic induction is considered, the size increases if we have to produce the required power.
Can you please help me at this point as this would help my project?
Children's shoes frequently have flashing lights in them. They are powered by a rolled up sheet of PVDF. Some are LEDs and some are neon lights. The neon lights need about 70 volts to flash.
