The effects of the structural deformation on magnetic characteristics of the single-walled chiral Toroidal carbon nanotube (TCNT) at a given temperature are investigated theoretically by using the tight-binding model. The results show that the persistent currents in a TCNT are very sensitive to the deformations. When the strain reaches 2% at T = 10K, the persistent currents in the (2,5, 360,480) metallic TCNT and the (2,5, 300,400) semi-conducting TCNT decline by about six and five orders of magnitude, respectively. It suggests that at a finite temperature the TCNT electromechanical system may possess important potential applications for making physical sensors (e.g. pressure sensors).
