Intracortical microstimulation consistently evoked tactile sensations in participants over a 10-year period, demonstrating its safety and reliability.
More than 168 million pulses were delivered without serious adverse events, underscoring the procedure's safety profile.
Five participants with spinal cord injury were implanted with microelectrode arrays to assess the longevity of tactile sensation restoration.
Results suggest that while detection thresholds increased over time, a significant portion of electrodes maintained reliable function for sensory restoration.
