High performance transducers are not available using today's ceramic piezoelectric materials. Single crystal materials have shown an order of magnitude improvement in the efficiency over ceramic materials. Lasergenics has recently demonstrated the growth of large, homogeneous single crystals of PZN. We will further improve on the growth of these crystals and then demonstrate with Fraunhofer USA that this material will greatly improve on the performance of medical transducers. We will demonstrate a thin and flexible composite transducer design developed by Fraunhofer USA using the single crystal piezoelectric material of Lasergenics. Such a transducer system would have wide application in many fields of medicine. A 2D sparse array will be developed in the Phase II program. PROPOSED COMMERCIAL APPLICATIONS: The successful completion of our proposed program will allow the development of flat and flexible transducers that could will have wide application in medical imaging and diagnostics because of the high resolution and efficiency they would exhibit.

使用当今的陶瓷压电材料无法使用高性能传感器。单晶材料显示出比陶瓷材料的效率提高了数量级。重血压最近证明了PZN的大型，同质单晶的生长。我们将进一步改善这些晶体的生长，然后与Fraunhofer USA证明这种材料将大大改善医疗传感器的性能。我们将使用Fraunhofer USA开发的薄而柔性的复合传感器设计，使用Lasergenics的单晶压电材料开发。这样的传感器系统将在许多医学领域都有广泛的应用。 II期计划将开发2D稀疏阵列。拟议的商业应用：成功完成我们建议的计划将允许开发平坦，灵活的传感器，这些传感器将在医学成像和诊​​断中广泛应用，因为它们将表现出很高的分辨率和效率。
