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.
