Core clinical engineering and protocols for Bidirectional Neuroprosthetics.
Modern commercial bionic hands offer advanced mechanical dexterity but zero sensory feedback: users must continuously watch the hand to know if they are crushing an egg or dropping a glass. Without somatosensory feedback, prosthetics feel like foreign tools rather than parts of the body.
NeuroLiaison delivers biomimetic electrical stimulation to sensory nerve fibers in the amputee's residual limb. When artificial fingertips contact an object, pressure data is translated into charge-balanced electrical pulses delivered to the median nerve, evoking vivid sensations of pressure, vibration, and texture that feel like the patient's own missing fingers.
