Design and Implementation of a Simulator of The Micro-Electromagnetic Generator Used to Power Medical Devices Implanted in The Human Body

The issue of obtaining sustainable energy to power small electronic devices that are difficult to power with batteries is considered one of the important research topics, such as Biomedical Implants, as it depends on the nature of these devices in order to power them themselves, noting that most of these devices are located in a vibrating medium, and thus energy can be secured. It has a micro-generator that converts ambient energy into electrical energy that is used to charge a small battery installed on the device implanted within the human body. Micro-electromagnetic generators are considered one of the most important types that convert vibration energy into electrical energy used to charge a battery. In this research paper, we conducted a theoretical study of the micro-electromagnetic generator, and deduced its mathematical equations, leading to the final model that links the vibrations to the generated voltage. This model was later modeled and simulated using MATLAB/SIMULINK, and we designed and implemented an emulator circuit for the generator that uses a dsPIC digital signal processor through which parameters can be adjusted via an interactive GUI interface to obtain the output of the micro-generator similar to the real one, with the aim of using it later in research into developing collection systems. Energy for Biomedical Implants. Finally, we applied practical designs of micro-generators found in previous research to the simulator that we designed to ensure the accuracy of the results.
