Description

Currently, many types of micro-valves are used for sealing applications. Some of the common ones are MEMS micro-valves and permanently sealable valves. However, the existing valves are associated with potential limitations such as inadequate sealing over longer time periods, leakage issues, and irreversible/non-reusable sealing. This approach discloses a novel, sealable micro-valve that can be repeatedly opened and sealed, as required.

 

Value Proposition

The micro-valve:

•Works on the basis of surface tension of a molten seal material

•Enables prevention of molecules or atoms entry from outside into a closed space

•Comprises a reversible, reusable, and a non-permanent seal, allowing for the opening and closing of a space

•Is substantially leak-free in the closed state and possesses a higher flow rate in the closed state as compared to conventional valves

•Would be commercially useful for variety of applications such as in microscale vacuum pumping systems, portable sensing systems for homeland security, military, healthcare/life sciences, and chip scale atomic clocks
