“…A self-assembly method [26,27] was proposed based on shape recognition and capillary drive, and achieved selfalignment of 1000 micro-components with the receptor site at the same time. A surface tension-based method for the directional transport and self-alignment of micro-fibers has been investigated [28,29], which enables precise positioning and rapid alignment of micro-fibers. Combining robotic microassembly techniques with surface tension self-assembly techniques, a self-alignment strategy for micro-chips on patterned hydrophilic/hydrophobic different substrates is proposed [30], and the performance of the micro-assembly is evaluated for the release of micro-devices and high precision self-alignment with the substrate.…”

Automatic alignment of micro-component position and posture is an important part of micro-assembly. A self-calibration method of micro-components based on a droplet manipulator is proposed. The shape of the operating surface of the droplet manipulator is changed according to the shape of the micro-component and a droplet of the corresponding shape is formed; the position and posture of the operating surface of the droplet manipulator is used as a guide to drive the rapid alignment through the recovery force of the liquid bridge to achieve self-calibration of the micro-component. The self-calibration principle and process are analyzed using rectangular and triangular micro-components as examples, and the effectiveness of the proposed method is demonstrated experimentally. The research and experimental results show that the self-calibration can be achieved by changing the shape parameters of the operating surface of manipulator and controlling the corresponding droplet form; the self-calibration of position and posture of micro-components with different shapes and sizes can be achieved by matching the operating surface shape of the droplet manipulator and the micro-components; the automatic calibration success rate is 100% under the condition that the contact surface of the micro-component is completely wetted.
