我们发现，一个水凝胶微弹簧是通过挤出海藻酸钠预凝胶溶液到氯化钙溶液中使用斜面尖端微流控毛细管。微弹簧的形成取决于毛细管的直径、流速和尖端角度。作为软致动器的一个例子，包括磁性胶体的微弹簧通过施加磁场来致动。我们相信，微弹簧将用于各种应用，包括使用软材料的机械元件。
We found that a hydrogel microspring was formed by extruding sodium alginate pre-gel solution into calcium chloride solution using a bevel-tip microfluidic capillary. The formation of the microspring depends on the diameter of the capillary, flow rate and tip angle. As an example of soft actuator, the microspring including magnetic colloids was actuated by applying magnetic fields. We believe that the microspring will be used to various application including mechanical elements using soft materials.
