Here, we have shown that the current through the films made from nitrogen-doped carbon nanotubes (NCNTs) changes as the pressure is varied between 93 and 1000 mbar. The change is due to adsorption and desorption of ambient oxygen. Interestingly, the devices show good responsivity even when the power is in microwatts range. Over all, a low cost and low power pressure sensor made from NCNTs were fabricated and their usefulness was demonstrated. We believe the same can also be used as an oxygen sensor.
