A nanomechanical computer—exploring new avenues of computing
Here is the abstract:
We propose a fully mechanical computer based on nano-electromechanical elements. Our aim is to combine this classical approach with modern nanotechnology to build a nanomechanical computer (NMC) based on nanomechanical transistors. The main motivation behind constructing such a computer is threefold: (i) mechanical elements are more robust to electromagnetic shocks than current dynamic random access memory (DRAM) based purely on complimentary metal oxide semiconductor (CMOS) technology, (ii) the power dissipated can be orders of magnitude below CMOS and (iii) the operating temperature of such an NMC can be an order of magnitude above that of conventional CMOS.
