electronic devices. This embedded nanometric circuitry would consist of nanoparticles, nanowires, transistors, resistors, voltage gates, capacitors, switches, ampliers, along with standardized connection formats. This nanocircuitry will organize and convey harvested or generated electron ow to and from all VCSN components and subcomponents. A solidstate quantum computing entity (Chapter 7) would reside as the heart of the VCSN, serve as a secondary control mechanism for the nanodevice, and play a vital role in the management of onboard nanoelectronics. Primary control will reside within “outbody” computers. Several layers of redundancy might be designed into the nanoelectronic infrastructure to ensure reliable and robust operational integrity. Additional attributes will include integrated safety parameter protocols, self-diagnostic elements, and (dormant until activated) circuit rerouting capabilities.
