Topic: locally enhanced electric field

Neural stimulation is an important technology not only for fundamental neuroscience studies, but also for therapeutic purposes and advanced devices like neuroprosthetics and brain machine interfaces. To achieve an accurate stimulation on a cellular level, invasive devices are normally used especially for deep brain stimulation. A widely used stimulation mechanism is by injecting current with microelectrodes, which has the limitation of tissue damage on the electrode/electrolyte interface. Another stimulation mechanism is based on microscale magnetic field, which requires complicated fabricatio
