AI Technical Summary

Technical Problem

Existing hearing aids have insufficient performance problems in terms of waterproof, sweat resistance, salt spray resistance, moisture and heat resistance, and thermal shock resistance. Structural protection will increase the volume of the equipment, and the three-proof paint protection may affect the transmission of electronic signals.

Method used

A waterproof coating is formed using a plasma polymeric coating including a silicone monomer, the coating includes a hydrophobic layer and a protective layer, which is formed on the hearing aid surface by plasma discharge technology.

Benefits of technology

It achieves good waterproofness, moisture-proof, corrosion-proof, salt spray-resistant, moisture-proof, heat-resistant, heat-resistant, heat-resistant, and heat-resistant, without increasing the volume of the equipment. The hearing aid function is normal in the accelerated environment test.
