Resumen:

This work deals with the case of a ring-shaped con-ductive solid material rotating at different speeds in a constant magnetic field. Their interaction induces a potential difference between the inner and outer radius of the disc, which is measured. This configuration corresponds to a Faraday's disc. It is important to understand the phenomena of electromagnetic induction for small-scale direct current generators, as Faraday's disc. These kinds of generators allow replacing the use of batteries employed on micro-scale applications such as small signal monitoring, medical apparatus inserted in human bodies, smart textile and smart skin devices that can monitor mechanical and thermal variables in the human body, etc. For these applications, it is of great importance to fully understand the underlying physics of these generators, for which experimental and theoretical analysis is employed. The generator's conceptual application in future stages is to collect the untapped kinetic energy found in several physical systems such as human body movement, and vibrations on machinery, among others. In this work, a Faraday's disk generator is analyzed experimen-tally and theoretically to understand the fundamental aspects of these devices. This allows for validating the theoretical models, which can be used to determine the output electrical variables (electric power, induced voltage, and current) of the system operating under given experimental conditions. Comparison results among experimental and analytical models are shown. © 2022 IEEE.
