受卵精通过输卵管平滑肌收缩滚动行为的启发，设计了一个简单的仿生实验，以揭示可能的机械运输机制。一个有趣的实验观察表明，弹性应变梯度可以用来通过滚动在可拉伸基底上传输软乳胶泡。建立了具有弹性的三维气泡在受应变梯度影响的弹性基底上粘附接触的理论模型。得到并分析了这种滚动运动的起始和稳态能量释放率。找出了影响轧制的因素。这一发现可能对设计具有应变梯度的主动输运系统具有普遍意义。
Inspired by the rolling behavior of oosperm through smooth muscle contraction of fallopian tube, a simple biomimetic experiment is devised in order to disclose the possibly mechanical transport mechanism. An interesting experimental observation demonstrates that an elastic strain gradient can be utilized to transport a soft latex bubble on a stretchable substrate by rolling. A corresponding theoretical model is established, in which an elastically three-dimensional bubble contacts adhesively on an elastic substrate subject to strain gradient. The initiation and steady-state energy release rates for such a rolling motion are achieved and analyzed. The influencing factors of rolling are found. The finding may have general implications on designing active transport systems with strain gradient.
