A Field-Theoretic Perspective on Three-Dimensional Contact and Perception

This study proposes a field-theoretic reinterpretation of physical contact, structure, and tactile sensation, based on electron cloud interactions at the quantum level. Challenging classical mechanical models of solidity and touch, it argues that short-range Coulombic repulsion between overlapping electron probability fields forms the minimal condition for structural coherence and perception in three-dimensional matter. Through analytical derivations, quantum simulations, and mechanotransductive modeling, the work connects atomic-scale electron cloud overlap with macroscopic properties such as pressure, resistance, and sensory activation. This framework bridges quantum field theory and biophysical perception, suggesting that the geometry of electron distribution—not classical mass or rigidity—serves as the substrate for spatial structure and contact interpretation. Implications span materials science, sensor engineering, condensed matter physics, and neurobiophysics.
