Abstract

Gas and smoke sensors have also benefited greatly from the recent advances in nanotechnology. This chapter introduces a carbon monoxide (CO) gas detector that uses gold nanoparticles deposited on an array of carbon nanotubes as a sensing element, in addition to a smoke detector that achieves miniaturization by replacing a bulky alpha particle detection chamber with a silicon nanostructure. These types of detectors will be available commercially within a time span of 1 to 2 years.
