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 »
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.More »
