Micro-Lid For Sealing Sample Reservoirs of micro-Extraction Systems
Project Description
We propose to develop a proof-of-concept micro-Lid (µLid) to tightly seal a micro-sampler or micro-extraction system. Fabrication of µLid would be conducted in the Detector Development Laboratory (DDL) using Micro-Electrical-Mechanical-Systems (MEMS) processes at NASA GSFC. The goal will be to fabricate µLid such that it's cantilever is actuated by a mismatch in coefficient of thermal expansion
The proposed µLid system is in effect an attempt to miniaturize an extraction system to a chip-cup system with integrated heaters capable extremley hot temperatures.
The µLid system will be composed of a silicon cup with a silicon lid, acting as the µLid. The hinge structure supporting µLid will be a bilayer composed of metal bilayer that upon a temperature change will actuate the bimetallic cantilever.
More »Anticipated Benefits
µLid is an Early Stage Innovation project that will help first mature this technology to eventually merge with other center invested technologies. Moreover, coupling µLid to other on-center microfluidic analytical technologies will allow for further technology maturation. µLid can integrate with other microfluidic instruments to form a more complete miniaturized system.
This projects helps achieve NASA's goal in miniaturization of spaceflight instruments to allow for low cost and enable the opportunity for long range missions.
