NeuroSuit: A Conceptual Design for a Scalable Full-Body Bidirectional Neuromuscular Interface Enabling Closed-Loop Sensorimotor Embodiment in Brain-Computer Interface Systems

NeuroSuit is a full-body wearable (or hybrid minimally invasive) neuromuscular in- terface that closes the sensorimotor loop. It routes decoded cortical motor commands to targeted peripheral nerve or muscle stimulation while simultaneously delivering high-fidelity sensory feedback (proprioception, touch, pressure, temperature, vibration) back to the cor- tex via bidirectional cortical implants. The NeuroSuit concept was independently conceived and publicly presented via an X thread in April 2026. Subsequently, a PhD researcher directed attention to the previously published ReHAB study (Herring et al., 2024). 1 This clinical trial had already demonstrated that the integration of intracortical micro- electrode arrays for motor decoding with selective peripheral nerve cuff electrodes can restore both volitional motor function and naturalistic somatosensory feedback (proprioception and touch) in a participant with tetraplegia. These findings provide direct empirical validation of the core bidirectional principle un- derlying NeuroSuit. NeuroSuit generalizes the approach to whole-body coverage and sup- ports scalable implementation tiers from clinical hybrids to consumer-grade non-invasive wearables. Ten high-impact applications are detailed, spanning neurorehabilitation, remote robotics, immersive VR/AR, accelerated skill acquisition, hybrid exoskeletons, elderly care, and hu- man augmentation. Technical architecture, challenges, regulatory considerations, and ethi- cal aspects are discussed. This perspective paper provides a foundational blueprint and invites collaboration toward realization.
