Project abstract

Gas Sensing Solutions (GSS) Ltd produces market leading carbon dioxide sensors integrating unique, innovative CO2 sensor technology for a wide range of applications. For this project, GSS has teamed with researchers from Glasgow Caledonian University (GCU) to investigate intelligent sensor systems with applications for the built environment, telehealthcare, and oil and gas industries.

Through the use of computational models known as random neural controllers (RNCs) developed at GCU, researchers led by Dr Hadi Larijani are investigating the possibilities for smart sensors as embedded intelligent self-learning systems. This would allow sensors used in a range of applications, such as building energy management systems, to anticipate and respond to changing conditions with minimal human intervention, helping to provide comfortable living environments, reduce power consumption and protect the environment.

The project aims to combine and develop random neural network (RNN) based self-learning intelligence with GSS sensors, providing control systems with minimum human intervention and improving occupant comfort and reducing energy wastage in building energy management. The project will provide a ‘fit and forget’ wireless control system, compatible with power from energy harvesting methods. This will allow for sustainable solutions in the built environment, specifically in relation to air quality, health and safety requirements, human comfort levels and energy reduction. Energy reduction will be achieved through efficient monitoring and control of building air handling systems and provision of building management systems and data. The technology has wider application to telemedicine and the oil and gas industry.

Initial focus will be on the building energy management systems (BEMS) application area and field testing, however at the end of the project a prototype will be presented to market. This will have gone through extensive end-user evaluation to enable a more customised, user-centric product for market launch. The secondary focus will be on developing and applying the intelligent self-learning platform to innovative use of GSS sensors within telehealth and mobile healthcare applications. This will provide assistive patient/health care technology, and monitoring and management of respiratory related disease and conditions.

Once these stages have been completed, the design and size of the product will be determined to ensure that it is useable within each unique situation and fits into its environment. There are various patents associated with the product development area already filed across the partners. It is envisaged that advanced prototypes and demonstrators will be delivered, demonstrating the product is both market and supply chain ready.

Project Impact

The new products allow technology to assist towards real time improved comfort levels and energy savings within buildings by extending performance of existing sensor technology products produced by GSS. Air quality will be improved, optimising air handling energy usage leading to a reduction in carbon emissions. Markets include building control, and architectural design construction areas where the sensors can better match zoned indoor air quality control with people occupancy in buildings. Monitoring of human exhaled carbon dioxide gas provides a direct and accurate real time measure of people occupancy. Through sensing of exhaled carbon dioxide, the product can provide a low cost portable measure of breath rate, monitoring as a vital sign and also monitoring management of respiratory conditions which are more prevalent in an ageing population and exacerbated by deteriorating air quality. Within oil and gas the product can detect hydrocarbon, providing early warning to users within all areas of the facility about potential threats to health and safety and flammability.

The product has the potential to impact many markets and improve existing markets to provide low cost and power consumption. It will improve quality of life and health and safety. There will be multiple channels and routes to market through direct sales, and the licensing of software. Growth is set to rise dramatically in the building applications industry alone. This will be compounded within Europe due to the introduction of 2002/91/EC Directive which gives new minimum requirements for indoor air quality within new and existing buildings. Similar legislation is being introduced in the USA. This will grow the market potential considerably, with self-learning intelligence combined with wireless ‘fit and forget’ deployment of the sensors aligned with current and emerging legislatively drive global market requirements.
