1. A system for deforming a material comprising:

  • a deformable material; and

    control logic configured to dynamically adjust a peak charging current to adjust an energy transfer rate of a DC-to-DC step up converter, the DC-to-DC step up converter applies, according to a predetermined pattern, a controlled charge to the deformable material and provides an increasing energy transfer rate to reduce a voltage step size to adjust a waveform according to the predetermined pattern.
