Welcome to our blog, where you can keep up-to-date with the latest P2i news and developments. We will post articles regarding news, events we attend, speaker presentations as well as explaining the nanotechnology industry.
About this time last year our booth was crowned the Best of Show at AudiologyNOW! 2011 and we are back exhibiting at this year's show which takes place in Boston from the 29th-31st March 2012.
Our fingers are crossed, hoping to win the Best of Show award again but our real aim at AudiologyNOW! 2012 is to promote and demonstrate our Aridion™ technology. Since the 2011 show, Aridion™ is now applied to approximately 60% of hearing aids worldwide, protecting them against water and corrosion damage which can occur where moisture, sweat and cerumen builds up.
These types of environments can all be found within and around the ear and are a significant factor in causing hearing aids to malfuction. Aridion™ signfincantly reduces the damage caused by liquid and moisture resulting in longer lasting devices and reduced return rates.
AudiologyNOW! is the world's largest gathering of audiologists and we are looking forward to once again showcasing how Aridion™ can revolutionize the performance of hearing aids for manufacturers and consumers.

On the back of the International CES and Mobile World Congress (MWC) tradeshows there has been an increased amount of discussion, and at times confusion on the difference between waterproof and water repellent electronics. In this post, we will shed more light and understanding on the subject, but before we begin, here is how each is defined:
Waterproof: Impervious to water
Water Repellent: Treated with a finish that is resistant but not impervious to penetration by water
Put simply, waterproof requires a physical barrier altering the device, water repellent does not change appearance and can be applied to any device.
How do electronics become waterproof?
The term waterproof is itself confusing as there are varying scales of 'waterproofness' that can be measured to determine how well electronics perform in and around water. This scale is known as the Ingress Protection Rating (IPX) and is based on a scale of 0-8 where 0 means it has no protection and 8 means it can handle continuous immersion in water. For example, an electronic device that has an IPX7 rating is protected against water submersion to a depth of 1m for no longer than 30mins. The level of water protection a device is capable of is usually highlighted by the manufacturer either on the device or in the manual.
For a smartphone to pass IPX6 and above, the devices physical appearance is normally compromized and this can be seen through the development of ruggedized handsets that feature protective rubber and plastic casings, as below:

Fast forward to today and what was clear from the coverage at CES and MWC is that there is a strong desire for devices to be able to withstand water or other liquids. But unlike the above, the devices that are now appearing and claiming to be waterproof are not basic phones but instead are the latest smartphones on the market. What's more, these devices do not appear to have a protective case at all.
How are these new devices waterproof?
Well the answer is quite simple, gaskets and O-rings. Before water can reach the valuable internal components where all our data is stored there are barriers in place in the forms of gaskets and O-rings. For quick reference a gasket is a mechanical seal which fills the space between two or more surfaces to prevent leaking while an O-ring is designed to be compressed between two parts creating a seal. While both these barriers stop water from penetrating inside the device they can still alter physical aspects of the device making them bulky as well as expensive to produce and purchase.
There is also another problem, these seals can be comprised by general use and over time the parts can move or be damaged should the device be dropped. If just one of these barriers were to break, water would then be able seep inside towards the circuit board and internal components, resulting in device failure and loss of data as the inside becomes exposed to water.
Why repellency over waterproof?
Firstly, we need to be clear what repellent means when talking about electronics and how it differs from waterproof. That is where Aridion™ comes in.
The key difference is that electronics treated with Aridion™ will still allow water to get inside. Does that mean the end of the devices life? Not necessarily, as Aridion™ molecularly bonds to both the inside and outside of the entire device ensuring that each and every exposed surface is coated. This means that any water that does come into contact will move away from the surface rather than sticking to the device and if water does get inside, the internal components are also treated, producing the same effect.
This type of protection allows the device to be created without having to compensate for a protective casing, gaskets or O-rings. What is important to remember however is that even though the water is repelled, the coating does not make the device waterproof as it is not designed to withstand submersion.
You can get a better idea of how the coating is applied and works in this video:
Aridion™ provides water protection by removing the buildup of corrosion. Corrosion occurs not just when a phone is submerged but in high humidity and moisture environments such as saunas, in the bathroom when having a shower or traveling through different temperatures. All these factors can lead to internal moisture buildup which over time can corrode the circuits. Aridion™ protects against this as it stops the water/moisture from sticking to and in between the components which would result in electrochemical migration. Electrochemical migration is the movement of metal ions between conductors and if this happens the device short circuits.
So what is the difference?
In the simplest terms, for a device to be waterproof it has to either be completely sealed and ruggedized (making them bulky) or alternatively it must have barriers in place which stops water from penetrating through. The disadvantage with that being these seals can break resulting in the device becoming susceptible to water and corrosion damage.
Water repellent does not mean waterproof but it does mean protection from splashes, spills, corrosion and water damage brought on by the scenarios mentioned earlier (humidty and moisture) as well as those 'caught out in the rain' moments we have all experianced.

The following video which was filmed at MWC with our CTO Dr. Stephen Coulson visibly demonstrates the benefits that Aridion™ offers to electronics devices:
Aridion™ is applied during the manufacturing process and is already applied to over 9 million devices including the Motorola RAZR and XOOM 2.
Having attended Mobile World Congress (MWC) for the first time last year we returned to Barcelona bigger and better.
Our booth at MWC 2012
With such a great show in 2011 we hoped that this year would bring similar results and we were not wrong, in fact the the buzz and coverage we recieved surpassed all our expectations.
Before MWC officially kicked off we attended ShowStoppers, a media only event that allowed us to demonstrate our Aridion™ technology to media and journalists from around the world as well as answering any questions they had. Over the course of the day we were interviewed by leading technology sites including Mashable and BBC Technology.
MWC which ran from the 27th February to the 1st March, the pattern continued as we carried out almost hourly interviews and demonstrations and you can see a collection of these interviews and videos by liking our Facebook page and clicking the links. We were also the topic of conversation for many podcast sites and you can listen to The Fonecast interview with our CTO, Dr. Stephen Coulson here and clicking on the Electronics tab.
In addition to this, MWC was also the venue to announce the winner of the Smart UK Project award. The Project was set up to find Britain's most innovative mobile company and despite not winning the award we were delighted to be a finalist from 79 initial company entries. You can watch the summary of the Smart UK Project awards here.
The show was a great success and you can see some of the images from our booth below:
