Towards synchronizing radio communication of In-Vivo nanorobots

Biomedical tasks in a physiological medium (blood) by nanoscopic programmable matters can be coordinated and executed efficiently by realizing a communication channel to and from the outside of the body. In this paper, we discuss the feasibility of self synchronized radio communication between nanorobots in the physiological medium. We present a magnetic-based method for synchronization, analysis, and a simulation for a previously designed carbon nanotube (CNT) based cantilever device, oscillating due to an electrostatic force to emit radio signals. A magnetic field can modify the electrostatic force, which induces the communicating cantilever device. A resultant magnetic field emitted from every nanorobot to its neighbors is suggested as a means for self-synchronization, where the sum of mutual influences gradually self synchronize the radio signals to form an in-phase higher amplitude strong signal. In another design, an external magnetic field is applied for a long enough period, assisting in establishing synchronization among the nanorobots. The radiofrequency enabling this communication is unlikely to affect the attached tissue due to their physical dimensions designed to conform to the Medical Device Radiocommunications Service (MedRadio) specifications.
