Abstract Glial scarring and passivization of long-term implanted neural probes is one bottleneck in brain- machine interface technology. However, ultraflexible probes with similar mechanical properties as tissue have been shown to minimize scarring and other biological responses. We propose a flexible, microscale neural probe that can be actuated using a electrolytically generated bubble. This device is designed to be able to record neural signals up to 100um away from the insertion site. To further avoid insertion damage, the speed of actuation can be controlled via the electrolysis rate. This design can allow for high-density, accurate neural recordings for a wide variety of clinical applications and research thrusts.
