Electrical brain stimulation (EBS) is a technique to stimulate neurons by current pulses. Charge accumulation due to these pulses leads to voltage build up, causing electrode corrosion and tissue damage. To ensure the safety and longevity of EBS oper

Fully-implantable, bi-directional brain-computer interfaces (BCIs) necessitate simultaneous cortical recording and stimulation. This is challenging since electrostimulation of cortical tissue typically causes strong artifacts that may saturate ultra-
