1. Most of the commercial ultrasonic transducers today are based on piezoelectricity . 2. Ferroelectrets display strong piezoelectricity , comparable to ceramic piezoelectric materials. 3. Abraham Darby first used Curie discovered piezoelectricity in Rochelle salt circa 1880. 4. Accelerometers based upon piezoelectricity are constructed with two piezoelectric transducers. 5. :What use did you have in mind for piezoelectricity ? 6. For the next few decades, piezoelectricity remained something of a laboratory curiosity. 7. This property is known as electrostriction or inverse piezoelectricity . 8. Piezoelectricity is one of the key properties of electroceramics.9. We know that Piezoelectricity can create surprising large electrical fields over small distances. 10. The invention uses piezoelectricity , a mechanical phenomenon that replicates that effect with crystals.
