Abstract: A system for processing biological or other samples includes an array of transducer elements that are positioned to align with sample wells in a microplate. Each transducer element produces ultrasound energy that is focused towards a well of the microplate with sufficient acoustic pressure to cause inertial cavitation. In one embodiment, the transducers are configured to direct ultrasound energy into cylindrical wells. In other embodiments, the transducer elements are configured to direct ultrasound energy into non-cylindrical wells of a microplate.

Abstract: An ultrasonic sensor in the invention includes an ultrasonic transmitter, an ultrasonic receiver, and a detector. The ultrasonic transmitter transmits pulse-shaped ultrasonic waves to a thin plate to excite the thin plate. The ultrasonic receiver receives direct waves and reflected waves among the ultrasonic waves propagating in the thin plate excited by the pulse-shaped ultrasonic waves, the direct waves propagating only in the thin plate, and the reflected waves radiating outward, then reflected by the object, and returning to the thin plate. The detector detects the object present near the thin plate on the basis of a difference between a time at which the ultrasonic receiver receives the direct waves and a time at which the ultrasonic receiver receives the reflected waves.
