Abstract

Abstract : A captive bubble that is translated by creating a moving apex on superhydrophobic foil at the right speed will create concentration gradients of the diffused gas species amenable to aerotaxis study and sensing. Abstract : Captive bubbles that reside on superhydrophobic surfaces with plastrons move uncontrollably when tilted. A system based on creating moveable local apexes on flexible superhydrophobic foils is shown to allow controlled transport. Simulations done reveal that specific bubble transport speeds are needed to form concentration gradients suited for aerotaxis study and sensing.
