In the 2014 Whitehead Memorial Lecture, a straight-forward charge-spring model was introduced and shown to yield estimates for the piezoelectric thickness coefficients of ferroelectric polymers such as polyvinylidene fluoride (PVDF) and of polymer ferroelectrets such as cellular polypropylene or tubular-channel fluoroethylene-propylene copolymer systems.
