Piezoelectricity

Please login with a confirmed email address before reporting spam

Hi everybody
I am doing my thesis about piezoelectric materials, specifically about one system that harvesters energy from human footsteps.
I have one problem with Comsol:
I have one piezoelectric generator subjected to a sin force
I can get the potential voltage of the piezoelectric , but now I want to couple one electric circuit for get electrical flow. But I cannot get. My question is : How can I couple one electric circuit for extract electrical energy from piezoelectric?
Thanks
