Piezoelectric Materials

piezoelectric materialsPiezoelectric materials are certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) that convert mechanical pressure to electrical energy (and vice versa).  Such materials are used in a wide range of devices including inkjet printers, speakers, watches and timing devices, actuators, sensors, and ultrasound imaging systems. 


Research Applications

The Penn State electroceramics faculty has led the field of piezoelectrics for more than 35 years, and in the last few years has pioneered the exploration of high strain piezoelectric single crystals, new high transition temperature morphotropic phase boundaries, high strain polymer piezoelectrics, copper metallization for piezoelectric fuel injectors, and thin film piezoelectrics for microelectromechanical systems (MEMS). There are 38 companies within Pennsylvania working with piezoelectrics and ultrasound. Penn State faculty members have extensive experience working with companies such as Agilent, Bridge Semiconductor, Intel, Northrop Grumman, Bosch, TRS Ceramics, and Wilcoxon Research. They are eager to continue the advancement of the Pennsylvania piezoelectrics industry.
