Sensory Feedback in Prosthetics Is Here—but Getting the Pulse Right Is Harder Than We Thought

Mechanism: Advanced prosthetic systems use sensors to generate neural signals via nerve implants, aiming to evoke natural touch sensations in the brain. Readout: Readout: Current systems achieve a 70% neural code match, while optimized systems aim for 95% for perfectly natural sensation, with proven longevity of 5+ years.

We can make prosthetic limbs feel. Small electrodes in the residual nerve, connected to sensors in the prosthetic hand, can evoke touch sensations that feel natural to the user. Recent systems show this works for years, not just days. The challenge now is not whether we can restore sensation, but how well we can match the neural code the brain expects.
