To overcome the limitations of invasive neuromodulation systems, we introduce a wireless magnetomechanical approach for remote, minimally-invasive deep brain stimulation (DBS) without chronically implanted hardware. This method leverages biocompatible magnetite nanodiscs (MNDs) with ground vortex magnetization, which undergo in-plane transitions under low-frequency alternating magnetic fields, generating localized piconewton-scale torques. These torques engage endogenous mechanosensory pathways ...
