Sensory prosthesis research has advanced at a rapid pace, yet standard stimulation pulse shapes have remained largely unchanged. Most prostheses typically utilize symmetric pulses to deliver electrical stimulation to peripheral nerves. Recent neurophysiological studies, however, have shown that these symmetric pulses do not always reliably evoke firings in stimulated afferents, thus impeding optimal restoration of sensory inputs to the brain. One promising strategy is the use of alternative pulse waveforms---specifically, asymmetric pulses, characterized by a brief, high-amplitude cathodic pha
