Appl. No.:

15/589477

Inventors:

- Palo Alto CA, US
Stephen R. Quake - Stanford CA, US
Michael Robles - Mountain View CA, US
Jason Khoo - East Palo Alto CA, US

International Classification:

F16K 99/00
F16K 99/00
F16K 99/00
F16K 99/00

Abstract:

A fluid valve is provided that includes a first planar substrate having a smooth surface or a surface with features, an elastomer disposed on the first substrate, a second planar substrate disposed on another side of the elastomer, where the second substrate has a smooth surface or features, where the first and second substrate are more rigid than the elastomer, where the first substrate, the second substrate or the elastomer has a fluid channel, where the channel is open when the first or second substrate are in a first thermal state or a first compression state, where the channel is closed or partially closed when the first or second substrate are in a second thermal state or a second compression state, where the second thermal state is a different temperature than the first thermal state, where the second compression state is a different pressure than the first compression state.

Abstract:

A fabrication method of a micromechanical valve includes: (1) forming a control layer according to a first weight ratio of cross linker: elastomer base; (2) forming a flow layer according to a second weight ratio of cross linker: elastomer base; (3) forming a membrane layer according to a third weight ratio of cross linker: elastomer base, where the third weight ratio is smaller than the first weight ratio, and is smaller than the second weight ratio; (4) bonding the membrane layer to the control layer to form a two-layer structure; and (5) bonding the two-layer structure to the flow layer to form the micromechanical valve.
