Methods for gas sensing with single-walled carbon nanotubes
First Claim
Patent Images
1. A sensing method comprising:
- providing at least one carbon nanotube;
biasing the at least one carbon nanotube;
exposing the at least one carbon nanotube to an environment where gas is adapted to be detected, whereby, in presence of the gas, heat is removed by the gas from the at least one carbon nanotube;
varying pressure inside the environment with the gas, whereby temperature of the at least one carbon nanotube changes with variation of pressure; and
detecting variation in temperature of the at least one carbon nanotube as an electrical response.
