N2 - Magnetoelectric (ME) coreshell devices have interesting applications in biomedical technologies including biosensing, and communication, due to their strong inter - coupling between the magnetostrictive core and the piezoelectric shell. This property could be utilized for specific applications in localized bio - stimulation of cells. This paper provides a conceptual proof of using the non - linear property of ME coreshell devices for frequency demodulation and stimulation. We use the Multiphysics simulation approach, wherein the ME coreshell was biased with a DC magnetic field and perturbed through dual coil alternating magnetic fields. The combined effect of the ME non - linear magnetostriction and the dual coil perturbation resulted in the demodulation of the interference frequency component, that induced equivalent 'electrical hotspots' on the piezoelectric shell. We provide a cross model verification, where the generated electrical current density on the piezo shell was provided as an input to a Hodgkin - Huxley (HH) neural cell model to actively induce membrane potentials on the cell. Future applications as a standalone, battery- and electronics-free, controllable, multi - functional and localized coreshells for targeted drug delivery, backscatter communication and bio - stimulation, is envisioned.
