Does this mean you can vary the coating thickness and density depending on the component?
Hogg: Yes, we can vary the coating according to requirements. We have already tested the process on neural implants. We encapsulated implants with our coating, placed them in a physiological solution and heated them to 80 degrees Celsius. This enabled us to simulate an implant lifespan of around 14 years at a body temperature of 37 degrees Celsius. That means, this particular implant would work inside the human body for up to 14 years.
We also coated microvalves that are implanted in the eye to control intraocular pressure. They contain a neodymium iron boron magnet (also known as NdFeB magnet) that is very prone to corrosion, which is why it needs a special protective layer that facilitates hermetic sealing.
Wearables are another interesting application for us. The electronic components in wearables are especially prone to corrosion due to sweat or water. Our innovative encapsulation technology extends their lifespan significantly.
Does this mean your process isn’t just used in medical technology, but is also suitable for other types of products?
Hogg: Yes, it is applicable in many different areas of electronics.
