Abstract
A microfabricated fluidic unidirectional valve includes a microfabricated elastomer material having a flow through channel. The microfabricated fluidic unidirectional valve also includes an elastomer flap attached to the elastomer material in the flow through channel. The elastomer flap forms a seal in the flow through channel to prevent fluid from flowing in a first direction through the flow through channel and to allow fluid flow in a second direction through the flow through channel.
Claims12
A microfabricated fluidic device comprising:
- first and second elastomeric layers each having one or more recesses formed therein, wherein the first and second elastomeric layers are bonded together;
- one or more input channels formed by the recesses in the first and second elastomeric layers;
- at least one output channel formed by the recesses in the first and second elastomeric layers;
- and
- a plurality of elastomeric chambers formed by the recesses in the first and second elastomeric layers,
- wherein the elastomeric chambers are configured to form a microfabricated fluidic analog element operable to perform an analog mathematical function by elastically responding to the one or more analog input signals in the one or more input channels to provide an analog output signal in the output channel, wherein a continuous change in at least one of the analog input signals causes a corresponding continuous change in the analog output signal.
