Seminar by Young Scientist Networks, Academy of Science Malaysia
||Topic: Chemical Sensor Technology for Smart Building: Opportunities and Challenges
Speaker: Dr Ng Sing Muk
Date : 14 April 2017
Time : 12.10 pm - 01.10 pm
Venue: Seminar Room 1
Sing Muk obtained his degree in chemistry from Universiti Kebangsaan Malaysia (UKM) and his PhD in sensors technology from The University of Manchester, UK. He is an expert in developing novel materials to be utilised in sensors application. These include synthesis of novel materials as sensing receptors, integration of material into sensing transducers, characterisation of new materials, modelling of sensor signals, etc. The targeted areas of the sensors are in the area of environmental monitoring, smart farming and biomedical, with the targeted analytes ranging from heavy metals, organic compounds such as volatile organic compounds, pesticides and herbicides to biomarkers for chronic diseases. Besides, he also develops simple sensor devices for on-line and on-site monitoring such as electronic nose and integrated apps with smart phones. Currently he is the Associate Director in the Research and Consultancy Office at Swinburne University of Technology Sarawak Campus.
Smart buildings are part of the core for future cities. Basically, smart buildings should be able to deliver services such as security, sanitation, air and water quality, illumination and surrounding comfort that increase the productivity and functionality of the occupants. It should be delivered at the most sustainable mode and with lowest cost for the financial, social and environment impacts. In achieving this, chemical sensor technology is one of the tools that can be integrated into the building during construction. It will be able to generate chemical information regarding the surrounding parameters to assist the occupants in making best decision in their daily life activities. Such approach can reduce unnecessary wastages while increase productivity. In the context of South East Asia, the use of chemical sensors is still quite limited as compared to physical sensors that detect physical parameters such as temperature and brightness changes. This talk covers some basic working concept of chemical sensors, relevant use of chemical sensors in building, some examples of chemical sensors, some case studies on the use of chemical sensors to protect the safety of the occupants and lastly the challenges to utilise chemical sensors in smart building in this region.
