The Design of a Piezoelectric Heart Assist Device
IEEE Transactions on Biomedical Engineering, 1975A piezoelectric heart assist device was designed, and preliminary tests were performed in vitro and in vivo. The device has the advantages of simple construction, low power consumption (approximately one watt), electrical rather than pneumatic drive, and noiseless operation.

Piezoelectric AlN film for SAW devices applications
1993 Proceedings IEEE Ultrasonics Symposium, 1993Polycrystalline AlN films with the c-axis oriented normal to the substrate surface, were deposited by RF reactive diode magnetron sputtering on fused quartz, silicon and sapphire. The films were characterized as to their morphology, optic and acoustic characteristics.

Parameterization of a Piezoelectric Nanomanipulation Device
Volume 2: Automotive Systems, Bioengineering and Biomedical Technology, Fluids Engineering, Maintenance Engineering and Non-Destructive Evaluation, and Nanotechnology, 2006Through measurement of hysteresis and drift in a piezoelectrically driven multi-axis multi-positioner nanomanipulator, we have quantified error over ranges of three primary operating parameters: gain, duty cycle, and actuation time. A total of sixty-nine curves were plotted, and error and drift measured in a single operating plane.
