Title: Michael R Zarnetske: Innovator in Hydrophone Technology
Introduction
Michael R Zarnetske is a notable inventor based in Bristol, RI (US), recognized for his contributions to the field of hydrophone technology. With a total of 4 patents to his name, Zarnetske has developed innovative solutions that enhance the performance and reliability of underwater acoustic devices.
Latest Patents
One of Zarnetske's latest patents is a parylene coating process for temperature-sensitive components. This method involves cleaning and promoting bonding on a transducer component through immersion in a mixture of isopropyl alcohol, deionized water, and silane. After air drying and rinsing in pure isopropyl alcohol, the component undergoes vacuum baking and is subjected to a vacuum for twelve hours. A parylene coating is then applied, followed by abrasion and rinsing with pure isopropyl alcohol. Finally, polyurethane is added to create a waterproof coating on the transducer component. In further embodiments, a second parylene coating can be applied outside the polyurethane.
Another significant invention is the physically damped noise-canceling hydrophone. This hydrophone features at least four piezoelectric sensors mounted to a central section of syntactic acoustic dampening material, along with a layer of corprene positioned between the sensors and the central section. Each piezoelectric sensor consists of radially poled piezoelectric cylinders wired in series with inert polycarbonate end caps and an isolator layer. The cylinders are assembled co-axially and adhered to the central section, which sandwiches a layer of corprene that adds noise dampening properties.
