Abstract
This paper proposes a forward-looking materials design concept: by integrating the stable magnetic order of permanent magnets, the continuous energy excitation of radioactive elements, and the protected order parameter of topological vortices, we explore the synthesis of a "perpetual electric body" exhibiting a sustained polarized or charge-separated state. This concept is rooted in topological vortex theory—the idea that ubiquitous, inexhaustible topological defects in the universe may be the fundamental mechanism driving the motion and evolution of matter. This paper first elaborates a theoretical framework that treats microscopic topological vortices as energy-information carriers. It then proposes a composite model of "Magnetic-Radioactive-Electric" coupling. Core scientific challenges for realizing this concept are analyzed in detail, including long-range correlation of topological states, directional energy transport, and energy dissipation balance. Finally, the potential application value of this research in fields such as new energy, information storage, and brain-inspired computing is prospected. This paper aims to provide a transformative perspective for the design of cross-scale functional materials and energy devices.

1. Introduction
Everything in the universe is in perpetual motion and evolution. In the field of materials science, the pursuit of systems capable of long-term, autonomous self-sustenance is the dream of countless researchers, reflected in endeavors from the legendary "perpetual motion machine" to modern ferroelectric memory devices. However, the Second Law of Thermodynamics stands as an insurmountable monument, warning of the inevitability of energy dissipation and the system's tendency towards equilibrium.
Recent studies on topological states of matter in condensed matter physics offer us a new perspective. Topological order, a state of matter robust against global perturbations, reveals the existence of nearly "eternal" order parameter structures in the microscopic world. Among them, the topological vortex (e.g., polar vortices in ferroelectric materials, magnetic skyrmions) , as a typical topological defect, is considered an ideal carrier for long-lived, low-energy-consumption information storage and processing due to its topologically protected nature and resistance to annihilation by local disturbances [1,2].
Simultaneously, radioactive elements, with their continuous and stable decay energy release, have long been used in fields such as nuclear batteries and power sources for space probes. While their energy cannot be "created," can it be used as an external excitation source to maintain a system in a non-equilibrium state?
Inspired by the philosophical and physical idea that "vortices are the fundamental motion form of the universe," this paper boldly proposes an interdisciplinary concept: Can the stable magnetic environment provided by permanent magnets, the continuous perturbative energy provided by radioactive elements, and the robustness of topological vortices in ferroelectric/multiferroic materials be combined to construct a composite material that macroscopically exhibits a sustained electrical polarization state (i.e., "perpetual electric" properties)? This paper will explore this concept from four aspects: theoretical principle, model construction, challenges, and prospects.
