“…The relationships between the arrays are reflected in the device height and the inclination of the array. It has been demonstrated that as for the widely used commercial transducers, the increase in the distance between ultrasonic elements in the same array leads to a decrease in ARF [20], which is detrimental to the distribution of the acoustic field. Therefore, in this paper, the ultrasonic transducers within the array are arranged most compactly.…”

“…Li et al studied the influence of different numbers of transducers on the acoustic field distribution for spherical arrays with fixed curvature and device height, demonstrating that phased arrays outperform traditional structures with only two opposing ultrasonic transducers in terms of levitation performance [19]. Sun et al employed circular, concave and plane array models to simulate and study the influence of various factors on the acoustic field model [20]. These studies have benefited the acoustic levitation technology based on ultrasonic arrays.…”

Acoustic levitation manipulation technology holds significant potential for applications in chemistry, biology, medicine, and micro-robotics due to its contact-less, adaptability, and safety advantages. The use of ultrasonic phased array is widespread in acoustic levitation, and the arrangement of the array plays a crucial role in this process. This study investigates the impact of array arrangement on concave and planar arrays. The acoustic levitation performance of concave and planar arrays is analysed with the maximum acoustic radiation force (ARF) and levitation range. The results indicate that concave and planar arrays exhibit similar trends with height in terms of ARF and levitation range and having a maximum value (for concave array, R = 38 mm and H = 67 mm in the z-axis, R = 34 mm and H = 61 mm in the x-axis, and for planar array, H = 66 mm in the long side and H= 55 mm in the short side). However, each array type’s ARF and levitation range variety follow opposite trends, with a maximum value when R = 90 mm and H = 195 mm for concave array and H = 165 mm for planar array. Adjusting the inclination of the array makes it possible to enhance the ARF and expand the control range. Furthermore, the optimal operating region of a concave array is concentrated at the intersection of the spherical axis (R = H/2 when varying the curvature and height, ϕ = φ when rotavating), while the planar array offers a broader range of manipulation due to its insensitivity to minor variations. This research reveals the influence of array arrangement on ARF and levitation range, providing valuable insights for designing and optimizing acoustic levitation devices.
