The Nanomorphic Cell 1 is a conception of an atomic level, integrated, self sustaining microsystem with five main functions internal energy supply, sensing, actuation, computation and communication. Atomic level integration provides the ultimate functionality per unit volume for microsystems. The Nanomorphic Cell abstraction allows one to analyze the fundamental limits of attainable performance for nanoscale systems in much the same way that the Turing Machine and the Carnot Engine support such limit studies for information processing and heat engines respectively. The Nanomorphic Cell concept is inspired by the trend, synergistic with semiconductor device scaling to use these core technologies for diverse integrated system applications.
