(A). Measurement setup to characterize the ultrasound field: (i) Langevin (ultrasound) transducer, (ii) metallic reflector, (iii) laser Doppler vibrometer (i.e. LDV), (iv) laser beam, (v) vertical positions of the laser beam (dashed lines) and (vi) glass plate that reflects the laser beam back to the LDV. As the LDV is moved vertically, the sound field in the AL can be determined. (B): Maximum spatial average pressure through the levitator (left) as measured with the setup demonstrated in Fig. 1A. Dashed lines (right, vii) represent the pressure nodes, (viii) is the E3 medium droplet in which the levitated embryo (ix) is immersed. Microscopy image (right) demonstrates a levitated embryo.
