AP23487678 – Development of a wide band, energy-efficient and compact converter of mechanical environmental vibrations into electrical signals
Objective of the project – is to develop a wide band frequency converter of mechanical environmental vibrations into electrical signals with a high degree of energy-efficiency.
Relevance: The relevance of the project is determined by the need to develop efficient alternative energy sources capable of utilizing mechanical vibrations from the environment. Most of these vibrations occur in the range from tens to hundreds of hertz, which requires the creation of broadband energy conversion devices. Existing technologies based on Faraday’s law face the challenge of simultaneously achieving high energy efficiency and a wide operating frequency range. Additional difficulties are associated with energy losses due to mechanical impacts and the effect of self-induction in the coil. Solving these problems requires interdisciplinary research in physics, electronics, and materials science. The development of such a device will enable the creation of autonomous power sources for low-power systems, including monitoring sensors, making the project promising in terms of practical application and commercialization.

Expected and achieved results: During the project, a schematic model of a broadband device for energy-efficient conversion of mechanical vibrations into an electrical signal was developed. A 3D model of the device was designed and optimized, considering requirements for compactness and minimal energy losses. A mathematical model describing the dynamics of interaction between magnets and the coil was created, including the effect of self-induction on output characteristics. A prototype of the device was manufactured using 3D printing, fully corresponding to the calculated parameters. An experimental test bench was developed and put into operation to study the device’s performance characteristics. Numerical calculations were carried out to predict the output voltage and energy efficiency of the system. Experimental studies confirmed the correct operation of the device within the frequency range of 1–60 Hz and at various vibration amplitudes. A parametric analysis of the influence of geometric parameters on output characteristics, including voltage and power, was performed. A comparison of theoretical and experimental results showed a high degree of agreement (correlation coefficient of 0.95), confirming the adequacy of the developed model. The obtained results confirmed the effectiveness of the proposed design and formed the basis for a scientific article submitted to the international journal Micromachines.
