A cross-like shape helps the electrodes of implantable neurostimulation devices to deliver more charge to specific areas of the nervous system, possibly prolonging device life span, says research published in March in Nature Scientific Reports.  The shape, called “fractal,” would be particularly useful for stimulating smaller areas, such as deep brain structures or the retina, since Read more about Microelectrodes optimized to enable a more energy efficient design for neurostimulation[…]
