“Siemens Hearing Instruments announces the world’s first application of nanotechnology to the manufacturing of hearing instruments. Using particles as small as 100 nanometers in size, Siemens developed an ultra-thin, anti-adhesive coating for the company’s newest BTE (Behind-the-Ear) models. Containing both oleophobic and hydrophobic properties, the instruments’ nanocoated housings repel water, sweat and other adherents - an issue for active children and adults who wear hearing instruments. By preventing moisture damage, nanocoating reduces moisture damage-related repairs, and ensures reliability and quality.” “By adding a nanocoated surface to BTE models, moisture and perspiration bead up and roll off the surface of the instruments, instead of seeping into openings such as the battery compartment or wearer controls. Reduced moisture inside of the instrument’s case means less corrosion and damage to internal components. Nanocoated housings are also easier to clean. Siemens offers nanocoating as a standard, no charge feature on its latest BTE products to ensure greater long term reliability and performance.”
