Piezoelectric transducers

[[email protected]]

Hi,

I am a student of ME. I am doing my final year project on
piezoelectric in shoes. Piezoelectric is located in shoes, while
walking, piezoelectric compressed and it generates an electric signal.
this electric signal is stored in capacitor in other words, this
electric signal charges a capacitor.

I need a piezoelectri for this application. which type of electric
suits? which specifications i need to buy it? do you have any idea ,
from where i can buy it online?

Thanks.

Even though the ceramic piezo materials have better power
generating properties, I think this application is probably
better suited to the flexible piezo films, just for physical
ruggedness.

You can find lots of information by Googling [piezo film].

But if you need the conversion efficiency of the ceramic
material, I suspect you will need lots of small pieces
embedded in an elastomeric material to prevent breakage,
with each piece coupled to the storage capacitor through a
bridge rectifier.

Although this may be an excellent project, I suspect
it will not be a good product. This is not harvesting
otherwise-wasted energy, it's extracting energy from your
stride. If you take very much, it will feel like you are
walking in sand... very tiring! On the other hand, that
*might* make a good product after all: Market it as
a special exercise shoe... <g>
