Original Abstract Submitted
Acoustic balances configured for weighing in ultrasonic non-contact manipulators, and associated systems and methods are described. In one embodiment, a method for a non-contact acoustic determination of a mass of an object includes capturing the object within an acoustic trap of an acoustic balance. The method also includes, in response to changing at least one acoustic parameter of the acoustic balance, changing an equilibrium position of the object; and in response to changing the equilibrium position of the object, causing the object to oscillate. The method also includes determining a resonant frequency of oscillation of the object; and based on the resonant frequency of oscillation of the object, determining the mass of the object.
