Neural stimulation safety and energy efficiency: Waveform analysis and validation
نویسندگان
چکیده
Energy efficiency and safety are key issues to accurately stimulate neural tissues. A novel waveform has lately been proposed: the rising exponential waveform; nevertheless, no experimentation has been done using an active model of the membrane in order to validate these results. This paper proposes this analysis using several types of waveforms. The total power consumption, taking into consideration the electrode-tissues interface impedance and neural tissues properties, is presented as a function of the waveform type and pulse width. Finally, a method to identify proper pulse current reversal is proposed. The rising exponential waveform is validated to be the energy-optimal and safer type of waveform.
