Purdue University researchers have developed a novel method of designing stimulus waveforms called Pulse Parameter Modulation (PPM). By pulsing the electric signal at the right rate the neurons respond the same way as they would to a continuous pulse with less impedance. This means that less power is needed to achieve the same effects, which will increase the lifespan of battery-powered implants and allows smaller stimulation electrodes with higher spacial locality. The pulsing can also be utilized to more selectively activate certain neuron populations (i.e. A, B, or C fibers) based on their activation levels and time constants.
