In vivo, the use of acoustic tweezers for precise manipulation of microparticles in the aqueous environment is both essential and challenging for biomechanical applications. In this research for 3-D manipulation, a three-dimensional phased array made up of 256 elements operating at 1. 04 MHz is developed. We demonstrate the 3-D levitation and translation of positive acoustic contrast particles, a key class of bioparticles, in water by various acoustic traps, and compare the positional change along the intended course by experimentally measured trajectories.
