Clear-tone Uses Nanotechnology to Protect Hearing Aids from Moisture

(Nanowerk News) Many hearing aid users have experienced the frustration of having their hearing aids malfunction and become damaged due to moisture and perspiration. One Tulsa company is employing nanotechnology to solve the problem.
MPS™ technology by Clear-tone incorporates an array of innovations that protect hearing instruments from moisture, corrosion, perspiration, and other contaminants. Completely invisible and acoustically transparent, MPS nanotechnology applies a moisture repellent protective bond that is over one thousand times thinner than a human hair.
The technology is molecularly bonded to every component inside and out, and makes water simply bead up and run off without adversely affecting the look, feel or performance of the instrument. Since the nanotechnology layer is molecularly bonded, it is extremely durable and lasts as long as the hearing aid itself.
Clear-tone's MPS nanotechnology works by applying a nanometer-thin polymer layer over the entire surface of a product. Using an ionized gas (plasma), this layer is molecularly bound to the surface and will not leach away. The process offers superior oil and water repellency by reducing the surface energy to ultra-low levels.
Frequently asked questions about the technology:
How does MPS liquid repellent nano-coating work?
MPS technology employs a special pulsed ionized gas (plasma), which is created within a vacuum chamber, to attach a nanometer-thin polymer layer over the entire surface of a product. The coating is molecularly bound to the product surface at a nanoscopic level, which means it becomes inseparable from it and is as durable as the material it protects. Because the coating is one thousand times thinner than a human hair, it is invisible to sight or touch.
How long does the treatment last?
During the plasma process, the monomer ionizes and chemically attaches to the surface of the product and so becomes part of the material. This way the treatment will last as long as the material it attaches to.
