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 interface 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 cortex 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). This clinical trial had already demonstrated that the integration of intracortical microelectrode 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 underlying NeuroSuit. NeuroSuit generalizes the approach to whole-body coverage and supports 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 human augmentation. Technical architecture, challenges, regulatory considerations, and ethical aspects are discussed. This perspective paper provides a foundational blueprint and invites collaboration toward realization.
