    　View Summary

    This paper presents an additive manufacturing method of an electrothermally controllable 4D-printed bimorph microactuator. We fabricated an electrothermal 4D bimorph microactuator equipped with an electrical heater through a two-step additive process: two-photon polymerization (TPP) 4D printing and liquid metal microfluidic injection. First, a 3D thermal bimorph microstructure including a microchannel was built using TPP printing. Second, the printed microstructure was electrically wired by injecting a liquid metal into the microchannel. To validate this method, we fabricated and characterized a vertical-spiral-shaped electrothermal 4D rotary microactuator with a large angular displacement. The fabricated electrothermal microactuator successfully controlled its temperature and angular displacement via electricity. Furthermore, we experimentally demonstrated the unique ability of the electrothermal 4D bimorph microactuator to produce repeatable large angular displacements of more than 10° at 386 mV. Accordingly, the proposed method is expected to enhance the spatial design freedom of electrothermal microactuators with potential applications in soft microrobotics.

    　View Summary

    This paper reports the design of a bi-directional VO2-KIRIGAMI electromechanical microactuator with a large millimeter stroke and low power consumption. Using Finite Element Method (FEM) simulation, it has been demonstrated that the proposed VO2-KIRIGAMI design can achieve a remarkable stroke of 2.2 mm with a power consumption of only 54 mW. This design study has enabled the application of electrothermal microactuators in long-range lens focusing for endoscopic procedures.

    　View Summary

    The diffusion coefficients of biological molecules, such as proteins, reflect their size, molecular structure, conformational changes, and inter-molecular interactions. Therefore, how the diffusion coefficient of biological samples changes in liquid solution is essential knowledge for clinical diagnosis and drug discovery. In this study, novel techniques such as (1) the simple fabrication technique of hydrogenated amorphous silicon, (2) the optical sorting technique for the high sensitive measurement, and (3) the new channel structure applicable for the biological sample, have been developed.
