Talk:Piezoelectric sensor

From Wikipedia, the free encyclopedia

I'm dubious about the claim that charges due to piezoelectricity in bones are the cause of local bone growth and replacement. Current research at stanford mechanical engineering (http://www.stanford.edu/group/biomech/faculty/carter.html) suggests that it's actually the flow of fluid through pores in the bone corresponding to the cyclic loading of the bones that actually is responsible for triggering growth.

The equations and explanations for the longitudinal and shear effects seem to be the same (except for the factor of two). What's the difference?
