abstract: Studies on gas sensor technology have intensified with the increasing demand in many fields which require high safety standard. In order to realize this aspect of utilization, gas sensors with improved sensitivity, selectivity and fast response time are critically needed to be developed. With the discovery of carbon nanotubes (CNTs), development is now focused towards CNT-based sensors because of their inherent properties such as small size, high strength, high electrical conductivity, low voltage operation, good stability, long lifetime and large surface area. CNTs are used as the active component in gas sensors. With ionization mechanism, the gas is sensed by measuring its unique electric field breakdown voltage. The non-aligned CNT has been tested as the gas sensing element, but there is still a critical need to produce and test vertically aligned CNTs, since they result in a higher electric field and lower breakdown voltage, producing a more efficient gas sensing device. The objective of the research is to improve the performance of the ionization-basedgas sensor using aligned carbon nanotubes array. Testing has been done using different equipments to check the characteristics of the Multi-Walled CNT (MWCNT) sample in comparison with the non-aligned CNTs which was previously designed. © 2011 Asian Network for Scientific Information.
