Abstract
A fluidic switch (or fluidic device) is provided. The fluidic switch includes: (i) a housing defining a cavity with a first opening and a second opening, the second opening being larger than the first opening, the cavity containing a viscoelastic substance, (ii) a channel to transport a fluid from a source, across the first opening, to a drain, where the first opening opens into the channel, and (iii) an actuator to apply a force through the second opening to the viscoelastic substance in the cavity when actuated, the force to displace a portion of the viscoelastic substance into the channel to impede transport of the fluid through the channel.
