This paper are focused to characterize the difference CNTs deposit on Titanium Oxide (TiO2) as metal sensing for formaldehyde molecule detection. The sensor was fabricated by using two types of CNTs which is Single wall carbon nanotube (SWCNT) and Multi wall carbon nanotube (MWCNT) for measuring the most suitable device for detecting the formaldehyde gas. Characterization of difference IDE pattern is demonstrated by various measurements.
