Crystals with this property, such as Rochelle salts, necessarily lack a center of symmetry.
Devices making use of this behavior can often be modeled as Butterworth-van Dyke equivalent circuits. Temperature-dependent resonant frequencies are a hallmark of resonators made out of materials with this property. It has direct and converse forms, the latter of which Langevin used in his sonar devices and the former of which is used in the quartz crystal microbalance. All ferroelectric materials have both pyroelectricity and this property. Crystals with this property, such as Rochelle salts, necessarily lack a center of symmetry. Discovered by Pierre and Jacques Curie, for 10 points, name this property in which voltage is generated by mechanical stress on a crystal.
