介电泳力已被用来在 1-癸醇油薄层的表面上产生具有正弦形态的静态周期性皱纹。当在叉指阵列中涂有油膜的相邻共面条形电极之间施加电压 V 时，就会发生表面变形。实验表明，对于一定范围的油膜厚度 (h)（15 至 50 μm）和皱纹节距 p（160、240 和 320 μm），皱纹鳞片的峰峰值振幅 A 根据函数形式 A 与 V(2) exp(-alpha(h) over bar /p) 成比例。 (C) 2010 年美国物理研究所。 [doi:10.1063/1.3525708]
Dielectrophoresis forces have been used to create a static periodic wrinkle with a sinusoidal morphology on the surface of a thin layer of 1-decanol oil. The surface deformation occurs when a voltage V is applied between adjacent coplanar strip electrodes in an interdigitated array onto which the oil film is coated. It has been shown experimentally that the peak-to-peak amplitude A of the wrinkle scales according to the functional form A proportional to V(2) exp(-alpha(h) over bar /p) for a range of oil film thicknesses (h) over bar (between 15 and 50 mu m) and wrinkle pitches p (160, 240, and 320 mu m).
