Energy-efficient pulses for deep brain stimulation

Gordon, Rauno / Min, Mart / Land, Raul


Energy-efficient excitation of neural tissue is investigated in this paper through the generation of optimal shape pulses. It is essential for neural stimulation to have a large percentage of the energy in the most useful frequency range. The useful range is above the frequency of the tissue-electrode interface capacitance and below the frequency of other parasitic capacitances (small capacitances of cables, connectors). One powerful observation to determine that useful range is that it centers on the minimum phase angle of the impedance. In this study we have generated stimulation signals in the form of short chirp pulses that have 95 % of energy in one decade of frequency range.
