(Fig 1a) Maximum velocity and acceleration of potential microneedle insertion mechanisms, analyzed by high-speed video

The motion of each commercially-available lancet and snap dome was captured using a high-speed video camera. The videos were analyzed using ProAnalyst software. The software was used to track a specified point on each actuation mechanism in each frame of the video. The velocity and acceleration were then determined for each actuation mechanism using the data output from the software.

采用高速摄像机采集了每一款商用在售柳叶刀（lancet）与弹片（snap dome）的运动过程。随后借助ProAnalyst软件对采集得到的视频开展分析：该软件可在视频的每一帧中追踪每个促动机构上的指定标记点，并基于该软件导出的原始数据，计算得到每个促动机构的运动速度与加速度。
