New Liquid Repellent Nano-Coating for Consumer Electronics Debuts in Hearing Aid Devices

Materials science innovator P2i has created AridionTM, a revolutionary liquid-repellent nano-coating technology that protects consumer electronics devices against damage from water and sweat, to improve their performance in challenging applications.

On surfaces protected with AridionTM unique nano-scale polymer coating one thousand times thinner than a human hair -- water forms beads and simply roll off. Thanks to this, AridionTM can transform the reliability of consumer electronics devices containing delicate, expensive components at high risk of liquid damage.

Although AridionTM has the potential to protect all kinds of consumer electronics devices, it is initially being targeted at manufacturers in the $3bn global hearing aid market. Thanks to the protection AridionTM provides, manufacturers will be able to improve profitability through reduced repair and replacement costs, will increase user confidence through improved reliability, and will deliver clear product benefits that support premium pricing. All of these factors combine to enhance brand image, sharpen competitive edge and increase market share.

Stephen Coulson, Chief Technology Officer of P2i, comments: "We're excited to have developed AridionTM as a unique protective nano-coating technology concept for consumer electronics, and delighted that we have found such a ready market for our benefits, within the world's fast growing hearing aid business. We are already achieving excellent results with two of the world's largest hearing aid manufacturers, who have recognised how our revolutionary technology will increase reliability and improve the user experience with their products."

Why AridionTM makes business sense for hearing aid manufacturers

AridionTM can be cost-effectively applied to finished products using compact, high-throughput P2i processing machines. These integrate seamlessly and effortlessly with existing assembly lines, are easy to scale-up, and can be operated by ordinary workers at the touch of a single button. In a typical production environment, one P2i machine can treat a hearing aid in less than ten seconds.

Although the AridionTM coating is imperceptible to users and does not affect hearing aid acoustic properties, it physically bonds to the product surface at a nanoscopic level and thus is as durable as the material it protects. Plus, because AridionTM effectively coats every aspect of a finished product, it protects much more thoroughly than alternative approaches where individual product components are treated prior to manufacture.

Superior protection is particularly important to hearing aid manufacturers marketing the latest receiver-in-canal (RIC) behind-the-ear (BTE) hearing instruments to new generations of users. Market share of these instruments, with their discreet appearance and comfortable open-ear fitting, rose from 26.4% in 2004 to 43.8% in 2006 (source: Hearing Aid Market: Low Penetration Offers Development Opportunities, Koncept Analytics 2008).

However, younger users have high expectations of reliable, extended performance as part of an active outdoor lifestyle, bringing an increased risk of warranty failures and inadvertent accidental liquid damage. Because RIC/BTE devices are delicate and contain expensive digital electronics, repair costs (to manufacturers via warranty failure, or users via accidental damage) are potentially very high, especially given the current trend towards wearing binaural devices; one for each ear.

AridionTM helps minimise these costs by providing ‘one-shot' protection against steam and humidity as well as sweat. The superior protection afforded by AridionTM includes improved battery life (by avoiding moisture short circuits), and preventing component failure due to saline corrosion (sweat).

AridionTM also helps reduce the risk of inconvenience due to component failure, which is a significant user-acceptance issue. In a survey reported by Koncept Analytics, 56% of users rated ‘fewer breakdowns' as highly desirable. Plus, thanks to its superior protection, Aridion could also benefit hearing aids aimed at children, people suffering cognitive disorders and people working in hazardous environments, due to the higher risks of damage in each case.
