State of the art packaging for implantable devices uses metal or glass housings that are reliable but limited from a miniaturisation viewpoint as well cost-intensive. We suggest hermetic and biocompatible thin film based on alternating organic/inorganic coatings further smart MEMS can be applied long-term implantation. The combination high intrinsic molecular density silicon oxide (SiOx) pinhole-free stress releasing poly-para-xylylene (parylene-C) films creates new composite material, which...
State of the art packaging for long-term implantable electronic devices generally uses reliable metal and glass housings; however, these are limited in miniaturization potential cost reduction. This paper focuses on development biocompatible hermetic thin-film based poly-para-xylylene (Parylene-C) silicon oxide (SiOx) multilayers smart microelectromechanical systems (MEMS) devices. For fabrication, a combined Parylene/SiOx single-chamber deposition system was developed. Topological aspects...
Biocompatible polymer films demonstrating excellent thermal stability are highly desirable for high-temperature (>250 °C) applications, especially in the bioelectronic encapsulation domain. Parylene, as an organic thin film, is a well-established material exhibiting barrier properties and often of choice biomedical applications. This work investigated impact on bulk four types parylene films: N, C, VT4, AF4. The films, deposited using standard Gorham process, were analyzed at varying...
During the coronavirus disease (COVID-19) pandemic, wearing face masks in public spaces became mandatory most countries. The risk of self-contamination when handling masks, which was one earliest concerns, can be mitigated by adding antiviral coatings to masks. In present study, we evaluated effectiveness sodium chloride deposited on a fabric suitable for manufacturing reusable cloth using techniques adapted home environment. We tested eight coating conditions, involving both spraying and...
Recent developments in urological implants have focused on preventive strategies to mitigate encrustation and biofilm formation. Parylene, a conformal, pinhole-free polymer coating, has gained attention due its high biocompatibility chemical resistance, excellent barrier properties, low friction coefficient. This study aims evaluate the effectiveness of parylene C comparison VT4 grade coating preventing urinary bladder pressure MEMS sensor system. Additionally, silicon oxide (SiOx) applied...
The demand for ultra-tight encapsulation solutions with excellent barrier and high conformality properties has increased in recent years. To meet these challenges, thin-film coatings have emerged as a promising solution. In this study, we investigate well-established silicon-based plasma-enhanced chemical vapor deposition (PECVD) metal oxide atomic layer (ALD) deposited at low temperatures (≤100 °C) regarding their abilities to address high-level 3D applications. Various combinations of such...
The ongoing outbreak of coronavirus disease 2019 (COVID-19), triggered by the rapid community spread severe acute respiratory syndrome 2 (SARS-CoV-2), has brought forward need for speedy testing and manufacturing face masks global use. Overwhelmed fast-growing demand disposable masks, many governments have recommended use of, elaborated design criteria for, reusable that are meant to slow down transmission SARS-CoV-2 in general population. Using aerosol particle size spectrometers, we...
While water vapor transmission rate (WVTR) measurement is standardly used to assess material permeability, a system able quantify liquid (WTR) highly desirable for implantable thin film barrier coatings. Indeed, since devices are in contact or immersed body fluids, WTR was carried out obtain more realistic of the performance. Parylene well-established polymer which often choice biomedical encapsulation applications due its flexibility, biocompatibility, and attractive properties. Four grades...
In the COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), face masks have become a very important safety measure against main route of transmission virus: droplets and aerosols. Concerns that contaminated with SARS-CoV-2 infectious particles could be risk for self-contamination emerged early in pandemic as well solutions to mitigate this risk. The coating sodium chloride, an antiviral non-hazardous health chemical, option reusable masks. To assess...
