    Abstract

    This paper reports research into the use of a crossed-electrode two-dimensional thick film lead zirconate titanate ultrasonic transducer array for particle manipulation under the control of electronics based on field programmable gate arrays. The array consists of 30 × 30 transducer elements defined by electrode crosspoints and works at approximately 7.25 MHz. Laser vibrometry of the array surface displacement profile demonstrates that single or multiple elements can be addressed and multiplexed with bespoke electronics. The array has also been demonstrated for particle manipulation with planar resonators. The results suggest potential to create dexterous acoustic tweezing devices with reconfigurable electronics and batch-produced screen-printed ultrasound transducer arrays with large number of elements.
