There is provided systems, devices and methods for system (100) for generating an acoustic-potential field of ultrasonic waves, using an array of acoustic micromachined ultrasonic transducer, MUT, elements, the array of acoustic MUT elements being comprised in one or more micromachined ultrasonic transducer, MUT; and having a controller being communicably connected to two or more of said acoustic MUT elements in said array, and being configured to control each of the two or more acoustic MUT elements to emit a modulated ultrasonic signal comprising a plurality of ultrasound waves towards one or more common focal points according to a respective phase shift of each of the two or more acoustic MUT elements, configured to cause the ultrasound waves of the modulated ultrasonic signals to be constructively combined at the common focal point(s), so as to generate an acoustic-potential field of ultrasonic waves.
