A metal alloy of nickel (Ni) and titanium (Ti), nitinol (NiTi) exhibits the properties of shape memory and superelasticity, which make it very useful for adaptation to conformal coatings. However, like parylene, nitinol is often difficult and expensive to produce; the extreme reactivity of the alloy’s titanium component requires exceptionally tight compositional control during combination [&he
Application of parylene’s xylylene monomer employs a chemical vapor deposition (CVD) process implemented under a vacuum. Unlike wet coating application methods – brushing, dipping, spraying, etc. – parylene CVD is not line-of-sight. Because the vaporous monomer envelopes all sides of the assembly being coated, appropriate process control allows vacuum deposition of an entirely conformal

Driving development of such emerging areas as microfluidics, advanced bio-sensing, capsule endoscopy, and personalized medicine, microelectromechanical systems (MEMS) are enabling an array of breakthroughs that promise to enhance patient care and outcomes. Protecting sensitive MEMS products from the harsh conditions both inside the body and out is Parylene conformal coating, which is helping to
