An exercise apparatus is provided having a torso support suspended at either end by a frame, which allows the torso support to swing from side-to-side in a pendular motion. The originator node generates a data packet and transmits the data packet to the proxy node. The series connection of the ferroelectric capacitors reduces the applied voltage across each, enabling the use of rough ferroelectric dielectric material, such as PZT deposited by MOCVD.
