An acoustic resonator device includes a fluid chamber with a carrier surface and a reflector surface. The fluid chamber is filled with a volume of a fluid that includes a phase-separate material such as algae. The carrier surface is coupled to a transducer, which may be a lead zirconate titanate (PZT) transducer. The transducer, when supplied with electricity, emits an acoustic wave-based output of an output frequency (e.g., ultrasound). A sensor may be used to track one or more eigenfrequencies of the volume of fluid, the acoustic resonator device, or some combination thereof. A controller may receive tracking data from the sensor and control the voltage source, the transducer, or some combination thereof to ensure that the output frequency matches one of the tracked eigenfrequencies, thereby maximizing excitation of the fluid to improve efficiency of mixing, stimulation, and separation of materials from fluid (e.g., for algal biocrude production).
