Here we present a review of often used and recently developed micromachining process for parylene c as well as a high level overview of state of the. In this paper we compared the surface properties and cell and protein compatibility of parylene c relative to other commonly used biomems materials. Micromachines 2018 9 x for peer review 2 of 25 using parylene coils 18. Conference series 715 012012. Here we present a review of often used and recently developed micromachining process for parylene c as well as a highlevel overview of stateoftheart parylene hybrid and free film devices for biomedical mems biomems applications including a discussion on its challenges and potential as a mems material. Parylene microsensors figure 3b were developed to measure intraocular stability 6. Parylene c is a widely used polymer material in microfabrication because of its excellent properties such as chemical inertness biocompatibility and flexibility. Parylene also exhibits low intrinsic stress optical transparency mechanical flexibility and compatibility with several standard micromachining processes and as such has been adopted as a structural material in the growing field of polymer based biomedical microelectromechanical systems biomems. Recent advances in the micromachining of polyp xylylenes commercially known as parylenes have enabled the development of novel structures and devices for microelectromechanical systems mems. Parylene etching techniques for microfluidics and biomems ellis meng1 and yu chong tai2 1department of biomedical engineering university of southern california los angeles ca usa 2caltech micromachining laboratory california institute of technology pasadena ca usa abstract parylene c polymonochloro p xylylene is a member of a unique family of thermoplastic crystalline polymers. It has been commonly adopted as a structural material for a variety of microfluidics and bio mems micro electro mechanical system applications. Parylene c which is traditionally used to coat implantable devices has emerged as a promising material to generate miniaturized devices due to its unique mechanical properties and inertness.
