Single Crystals Overview
TRS Single Crystal Capabilities
TRS can provide a number of different single crystals. We are currently focused on the development of PMN-PT piezoelectric single crystals for a variety of applications. We are focused on the medical ultrasound and Naval SONAR applications.
Single Crystal Piezoelectrics
TRS' new single crystal piezoelectrics possess exceptional properties and are
poised to revolutionize piezoelectric materials applications. In addition to
strain levels exceeding 1% (usable strain: 0.5% at 35 kV/cm), TRS crystals exhibit
five times the strain energy density of conventional piezoceramics.
Thus, unlike piezoceramic actuators that employ strain magnification
schemes, single crystal piezoelectric actuators can deliver higher strain levels
without sacrificing generative force. The high electromechanical coupling of
TRS crystals (>90%) increases transducer bandwidth, resulting in greater sensitivity
and acoustic power. In addition, low strain hysteresis results in improved high
power efficiency, and lower acoustic impedance than piezoceramics allows
for easier matching to air or water. High coupling also leads to dramatic improvement
in passive vibration damping.
