William A. Tiller introduced the concept of Intention Imprinted Electronic Devices (IIEDs), electronic circuits conditioned by focused human intention to emit subtle energy effects with measurable influence on physical and biological systems. These devices functioned as static intention carriers, operating with a fixed imprinted informational state. In contrast, the Healy system represents a new class of dynamic intention-coupled devices, in which physical noise generators and resonance algorithms select frequencies that are delivered as coherent signals to the human body. This process not only allows entrainment of endogenous oscillations into states of physiological coherence but also integrates the intention of the user into the ongoing interaction. We propose that Healy unites two hypotheses: (1) it functions analogously to a Tillerian IIED, in that intention interacts with electronic processes, and (2) it serves as a coherence-restoring device, delivering structured, periodic signals that promote entrainment across biological levels. This synthesis offers a conceptual framework for understanding frequency-based integrative medicine, bridging subtle energy research with modern biophysics of coherence, and is supported by the presentation of results from four blinded studies conducted with the Healy system.
