  Magneto-inductive (MI) Terahertz (THz) wireless channels provide significant
theoretical performances for MI communications (MIC) and wireless power
transmission (WPT) in nanoscale networks. Energy harvesting (EH) and signal
generation are critical for autonomous operation in challenging medium
including biomedical channels. State of the art electromagnetic (EM)
vibrational devices have millimeter dimensions while targeting low frequency EH
without any real-time communications. In this article, graphene resonators are
combined with single molecule magnets (SMMs) to realize nanoscale EH, MIC and
WPT with novel modulation methods achieving simultaneous wireless information
and PT (SWIPT). Unique advantages of graphene including atomic thickness,
ultra-low weight, high strain and resonance frequencies in the Kilohertz to
Terahertz band are combined with high and stable magnetic moments of
Terbium(III) bis(phthalocyanine) SMMs. Numerical analyses provide tens of
nanowatts powers and efficiencies of $10^4 \, W/m^3$ in acoustic and ultrasound
frequencies comparable with vibrational EH devices while millimeter wave
carrier generation is numerically analyzed. Proposed model and communication
theoretical analysis present a practical framework for challenging applications
in the near future by promising simple mechanical design. Applications include
nanoscale biomedical tagging including human cells, sensing and communication
for diagnosis and treatment, EH and modulation for autonomous nano-robotics,
and magnetic particle imaging (MPI).
