Abstract To obtain a multi-signal nano device in a nano-electromechanical system (NEMS), a new converter is designed with a single-walled carbon nanotube (SWCNT) acting as a rotary motor, and multiple-walled (such as the triple-walled used in the present study) carbon nanotubes (MWCNTs/TWCNTs) acting as a converter. The dynamic response of the system is investigated using molecular dynamics (MD) simulation. In the system, the rotary motor has a specified rotational speed as an input signal. The outer tube in the bearing is fixed as a stator and the inner tubes' responses are used as output signals. When using hydrogen atoms to modify the tube ends, the differences among the rotational frequencies of the motor and the inner tubes are very large. The inner tubes act as oscillators or rotors or both of them depending on the difference among their radii.
