Abstract: An implementable model and simulation of an oscillating Carbon Nanotube (CNT) for radio communication in nanorobots is presented. A cylindrical CNT cantilever beam, operating under constant direct current supply, is forced to continuously oscillate by applying a controlled electromagnetic force. Oscillation parameters are computed and simulated, including the maximum tip displacement, the acting electromagnetic force and the dynamic response of the CNT, yielding a frequency of oscillation. We develop a model to predict the oscillation frequency of the cantilever beam based on its properties, including the device geometry. The primary functional component of the system is the electrically chargeable cantilever beam which oscillates due to its electric charge and discharge, where the discharge happens when the cantilever moves closer to the counter electrode. Thus, we provide an implementable design of in-vivo transceiver, suitable for future large-scale applications based on radio communicating nanorobots. A swarm of such nanorobots can be regarded as implementable programmable matter. Graphic abstract: [Figure not available: see fulltext.].
