Coatings and Processes for Biomedical Applications

As medical device manufacturers are pressed to design ever-smaller devices with increased longevity, optimizing the performance and profile of each component becomes more crucial. Consequently, electrode coatings and surface solutions have been the focus of many device and component manufacturers in the cardiac rhythm management, electrophysiology, neurostimulation, and cochlear sectors. With the overall objectives of improving biocompatibility, surface area, electrical conductivity, and electrochemical performance, thin films and coatings have gained significant attention in these markets. For example, electrodes with enhanced surface properties for cardiac pacing, sensing and recording applications or electrodes connecting brain and machine have demonstrated significant promise.

In all applications of implantable electrodes for these devices, improving the coupling of electrical charge and electric field between the biological system and the underlying electrode is extremely important so that electrodes are effective and can be miniaturized to eliminate problems associated with size, scar tissue, increased trauma, longer healing times, and system rejection. Many coating and thin film systems such as platinum group metal alloys and oxides, high surface area TiN coatings, etc. (primarily synthesized and deposited using physical vapor deposition methods), are aimed at the improvement of the charge coupling and therefore, enhancing information exchange between the biological fluid and the electrode.

Real-time medical data recording, real-time physician engagement and active feedback control of biomedical systems is exceedingly crucial nowadays since they would cover extended monitoring of disorders, pain management, neurostimulation, and other disorders. The use of novel coatings and surface solutions provides benefits in these device platforms through enhanced electrochemically active surface area that has become increasingly crucial in advanced devices benefiting from various platforms such as flexible electronics, wireless sensor platforms, intelligent data infrastructure, and embedded systems. This field is closely related to the 2020 TechCon theme Communication 2030.
