Abstract: An acoustic tweezer is disclosed. The acoustic tweezer includes a function signal generator configured to generate a function signal for an ultrasound signal, a power amplifier configured to amplify the ultrasound signal based on the function signal, and an ultrasound transducer of a single channel in which a hologram thin film having different thin film thicknesses for each region is attached to an ultrasound oscillating surface of the ultrasound transducer, and the ultrasound transducer is configured to generate a plurality of ultrasound signals having different phase differences by allowing an oscillated ultrasound signal to pass through the hologram thin film.
