本文描述了实现多个复杂驱动的刺激响应型水凝胶微弹簧(SR弹簧)。利用斜尖毛细管连续形成了由p(NIPAM-co-AAc)和海藻酸钙双网络水凝胶组成的SR弹簧。在弹簧形成过程中，通过控制流量、浮力和层流流动模式，SR弹簧的尺寸、节距和横截面模式是可变的。通过加热单层或双层SR弹簧，我们实现了五种不同类型的复杂弹簧运动：横截面压缩、轴向压缩、轴向膨胀、卷曲和卷曲。我们相信，我们的SR弹簧可以为各种微型化学机械应用铺平道路，例如自主软机器/机器人和药物释放系统。
This paper describes stimuli-responsive hydrogel microsprings (SR springs) for realizing multiple and complex actuation. SR springs, made of double network hydrogel of p(NIPAM-co-AAc) and calcium alginate, were continuously formed by using a bevel-tip capillary. The size, pitch and cross-sectional pattern of SR springs were variable by controlling flow rate, buoyancy force and laminar flow patterns during the spring formation process. By heating single-layered or double-layered SR springs, we achieved five different types of complex spring movements: cross-sectional compression, axial compression, axial expansion, winding up and winding down. We believe that our SR springs could pave the way to various microscale chemomechanical applications such as autonomous soft machines/robots and drug release systems.
