Background

Touchless Innovation, trading as Sanodaf, is a company that specialises in advanced disinfection and decontamination technology.  Their aim is to create, design and manufacture innovative processes and products to help eradicate micro-organisms and infections that can cause health issues in everyday life for people and animals.  They have experience of disinfection and decontamination as a service company and were looking at new devices to enhance current hygiene technology.

With expertise in environmental decontamination, Touchless Innovation developed a novel prototype of an easy-to-understand and cost-effective hand-hygiene device.  It was based on the simple principle of using ultraviolet to kill micro-organisms that are commonly found on hands, specifically using UV-C which is proven technology for eradicating pathogens.  The prototype was a hand sanitiser unit that prompted the user to place their hands inside an aperture that delivered a short transmission of UV-C directly onto hand surfaces.  The unit was automated and, upon entry, a timed exposure to UV-C would be experienced by the skin.  It was a touchless process and the unit would indicate when hands could be removed.  The entire process was delivered quickly and without any noise or residue.

Specialist UV-C devices are used in laboratory settings but there was not an accessible device for everyday use. The creation of this device would allow people to efficiently sanitise hands without access to washing facilities and within a much-shortened time period.

Challenge

The company did not have the required expertise to test the device and demonstrate the intended claim that it kills 99.9% of MRSA after a short exposure on the hands and that it was also safe for human exposure.  The practical work to test the device required a respected Category 2 laboratory facility and testing by an independent body for credibility. 

Solution

Interface connected Stuart White, Director of Touchless Innovation, with Edinburgh Napier University as it had the laboratories, expertise and bacterial strains required to carry out the microbiological aspects of the work.  This collaborative project was funded by a Scottish Funding Council Innovation Voucher.

Benefits

The results of the project allowed the company to identify any potential areas for design improvements and confidently market the device as a high volume, commercial product.  Given the robustness and limited cost, it was considered that the portable version of this device would have an immediate market, both domestically and internationally.

The success of this product would improve the ability to sanitise hands in everyday situations to fight infections and ill health and would create jobs in Scotland where the device would be manufactured.  The product had wide market appeal and the company’s intention was to expand globally into other markets where hygiene is poor and access to clean water restricted. 

The company also planned to have a version of the device to be used in disaster situations where there was no power or clean water and a high risk of illness and infection spread. 

It has been a privilege to work with the team at Napier; they have shown a high level of interest in the project from day one and demonstrated a very professional level of competency in undertaking the project, and in publishing the final result.  This now leaves my company able to grow and expand with this product and I hope to be able to work with the team at Napier again.  The result of this collaboration will make a very positive impact as we can now press ahead with the creation of working prototypes and move closer to releasing this product onto the market place.  We are aiming to sell it in the UK and overseas and this will be a significant step for us as an SME (small or medium-sized enterprise).  Stuart White, Director, Touchless Innovation

It was an excellent experience working with Touchless Innovation.  The partner was extremely enthusiastic about their product but also realistic with the aims of this project.  I look forward to working with them again.  Dr Nick Wheelhouse, School of Applied Sciences, Edinburgh Napier University

Follow-On Activity – Advanced Innovation Voucher

Following on from their initial project with Edinburgh Napier University, Touchless Innovation were looking to collaborate with a university partner to verify that electrostatic spraying of hydrogen peroxide was a more efficient method of decontaminating hospital rooms than fogging, the current standard method used in the NHS.  Interface was able to successfully connect them to the University of the West of Scotland (UWS) where the company had access to the University’s specialist category 11 containment facilities, including the facilities required to undertake testing of the fogging and electrostatic spray disinfection delivery systems.  This project was funded by a Scottish Funding Council Advanced Innovation Voucher.

Benefits

The results of the project confirmed the company’s expectations as well as highlighting some additional considerations for future treatments and applications.  A full submission of the results was made to the NHS and Health Improvement Scotland.

Follow-On Activity – KTP

The current approach to disinfection/decontamination utilises two separate units: a fogging system and an electrostatic sprayer; the former being used to transform the disinfectant liquid into a dry fog for areas that can be effectively sealed off, and the latter which adds a negative electrostatic charge to the solution ensuring it surrounds and adheres to all surfaces it touches (for open-area use where traditional fogging would not be appropriate).

As the company had no engineering capability, they formed a Knowledge Transfer Partnership (KTP) with UWS to develop a unique combined fogging and electrostatic spray disinfectant device for commercial use – two different technologies to run from one power source. This would underpin rapid business expansion and ensure the UK is at the forefront of market-led technology, addressing both societal and economic impacts of poor hygiene control within public and private buildings.

Benefits

Business – Prior to the KTP, the business was dependent on external suppliers/market forces, limiting the control of their own direction. The KTP has enabled the business to become a manufacturer of their own device, allowing them to compete in a wider market and decide their own path.

They have benefitted greatly from being involved in the process of designing and creating a new concept for a device and then being able to carry this through to product build and test. The process has helped the business understand manufacturing and the issues around supply chain, in-house and external expertise and how these are linked in the creation of a new product.

Finally, the investment has enabled the business to acquire the global Sanondaf brand, operating across multiple territories and with ready-made customers for their new combined electrostatic/fogging unit. 

Academic – The project, based on an Advanced Innovation Voucher, allowed a strengthening of the relationship with a fast-growing business as well as providing an opportunity for cross-school collaboration between the School of Health and Life Sciences and the School of Computing, Engineering and Physical Sciences. In addition, the project provided an opportunity for:

• Demonstrating research impact for downstream REF reporting and publications
• Impact against UN Sustainable Development Growths in line with corporate strategy
• Further KTP portfolio growth for School and UWS in line with 2025 strategy
• Potential for further collaboration with the business. 

Our experience of the KTP scheme, working with UWS, and the support on offer from Innovate UK has been exceptional and we are on the cusp of rapid business expansion as a result. I would thoroughly recommend the programme to any ambitious business that is looking to innovate and embed new knowledge within their organisation. Having seen the capabilities of the model, we are already framing a potential follow on KTP – Stuart White.
