Improve reliability of hearing instruments using nano technology

Historically, hearing aids have been prone to damages by foreign materials. Manufacturers have applied various techniques to address this issue, most recently by using hydrophobic nano coating. However, these methods have shown to be inadequate, especially in dealing with oily substances such as earwax. HydraShield2 nanotechnology has been developed to mitigate the ingress of both water and oily substances for hearing aids. This was accomplished by significantly modifying the surface's interaction with foreign materials. Through both lab tests and human subjec tstudies, this technology has been found to be very effective in mitigating the ingress of foreign materials. As a result, the reliability of hearing instruments has been enhanced and the customers' satisfaction has been improved.
