Do you know how i can convert pressure or force excerted on an object to electricty?

could you please tell me the method as well as equipment and if possible your referenceDo you know how i can convert pressure or force excerted on an object to electricty?
this is a strange ability of some materials called piezoelectric crystals (quarz or ceramics for example).


if you apply some force to them will generate electricity and the other way round,the electricity is converted to deformation of the crystal.this method is applied in eco tomography.for reference you could read biophysic book .


I found this for you:

Piezoelectric is the word to use in an internet search.





Examples of the effect:


1. winter green lifesavers; bite one in front of a mirror in the dark


2. the igniter on a gas stove; a hammer in the igniter hits a ceramic that triggers the spark
