More Information
Summary:A peristaltic micropump includes one or more flexible channels configured to transfer one or more pumped fluids, and an actuator configured to engage the one or more flexible channels and rotate about a central axis. The actuator includes a plurality of rolling elements and a driving element configured such that the driving element operably rotates about the central axis and each rolling element operably rolls about a respective axis that is not parallel to the central axis. The plurality of rolling elements is disposed between the one or more flexible channels and the driving element. The driving element includes a cage configured to capture the plurality of rolling elements such that the plurality of rolling elements is located at different radii from a center of the cage.
