Data underlying the publication: Oscillatory rheotaxis of artificial swimmers in microchannels

Oscillatory rheotaxis of a 50µm droplet microswimmer in a 100µm wide microchannel (quasi-2D confinement) under varying imposed counterflow. Data source for the experimentally recorded oscillatory motion published in https://arxiv.org/abs/2106.10222, with fits to a hydrodynamic theory model. See the paper and supporting information for details. File guide: rheotaxis.mp4: x264 compressed video meicroscopy data of rheotaxing droplet, frame rate 25 fps, raw data available on request trajectory.txt: droplet coordinates (for rheotaxis.mp4) for trajectory analysis provided as ASCII, with time stamps and droplet radius (see file header) description.docx: instructions for mathematica and matlab scripts provided to replicate the plots of the theory model.

本数据集聚焦于50微米级液滴微游泳器（droplet microswimmer）在100微米宽微通道（microchannel）内、准二维约束（quasi-2D confinement）环境中，于可变外加逆流（imposed counterflow）条件下的振荡趋流性（oscillatory rheotaxis）行为。
本数据集的实验振荡运动数据源自发表于arXiv:2106.10222的研究工作，同时配套了流体力学理论模型（hydrodynamic theory model）的拟合结果。详细信息请参阅该论文及补充材料。
