Abstract

A mechanical input to a fluidic filter network can be actuated. The fluidic filter network can include respective branches fluidically coupling the mechanical input to respective deformable mechanical outputs. A mechanical displacement can be selectively coupled a selected deformable mechanical output of the fluidic filter network to a deformable mechanical input of a microfluidic device. A fluid flow in a portion of the microfluidic device can be controlled using the displacement, the selected deformable mechanical output can be selected at least in part by actuating the mechanical input to produce a displacement having energy in a specified range of frequencies, and the fluidic filter network is generally fluidically isolated from the microfluidic device.
