TLDR
In this article, a novel mechanical airborne filter to check the concentration gradient of airborne particles is discussed in which a polymerized coating is carried out to avoid the rapid oxidation of frame work.Abstract:
A novel mechanical airborne filter to check the concentration gradient of airborne particles is discussed in this article. The system proposed here is experimented to detect the airborne microbes and its concentration analysed with the Chemical based Chromatography test. The proposed system which uses Silicon derivative material for the design of filter frame and an polymer material is coated over it. The polymerized coating is carried out to avoid the rapid oxidation of frame work. The system is equipped with the Contraction chamber and also the vacuum chamber equipped with chemical solvents. The entire Computational modelling carried out with Comsol multiphysics tool.read more

A Parylene micro check valve
TL;DR: In this article, a micro check valve with a twist-up tethered Parylene-membrane is presented, which has low cracking pressures (less than 0.5 kPa for nitrogen), high reverse pressure (seater than 600 kPa) and low reverse leakage (undetectable with a 0.2 ml/min flow meter resolution).

A MEMS thermopneumatic silicone membrane valve
TL;DR: In this paper, an integrated normally open valve using a silicone rubber membrane and 3M PF5060 liquid for thermopneumatic actuation has been fabricated and tested for a 1.3 lpm air flow, 280 mW is required to close the valve at 20 PSI inlet pressure.

A practical thermopneumatic valve
TL;DR: In this paper, a thermopneumatic silicone rubber membrane valve was proposed to switch a one slpm nitrogen flow at 33 psi using less than 40 mW. This valve has been extensively characterized with respect to power consumption and transient response.
