Narrative Report

In general, I was able to explore the different application and modern responsibilities of Electronics Engineering in the biomedical field.

From the basics, I was able to learn the different bodily systems and how they function. These fundamentals helped me understand how the technological sector aids in ensuring quality life. For example, it was taught that motions of our cells and fluids could be measured in millivolts or less. Applying the principles of Electronics, inventors of different medical machines and apparatus used sensors to detect these unnoticeable muscle responses and amplify the small voltages into larger amplitudes. These data could be used in monitoring the bodies of patients in rehabilitations, especially in knowing if the body is responding positively or showing motion on parts that were previously affected by stroke and similar events.

Along with the many known medical machines and devices such as MRI, ECG, EEG, etc., we also learned about the advancing robotic prosthetics that could be controlled by the clients with the joints triggered only by very small amount of body voltage being amplified to the prosthetic sensors. There are also neurological scanners being used in analyzing brain activities and they play crucial roles in today’s mental health awareness.

Not only are the history and descriptions of the electronic devices in biomedical field introduced, but the concept behind them are discussed. Some of the discussions include data acquisition and its transformation into imagery, how piezoelectric ultrasounds work, and how the different body scanners work using the magnetism principles.

Overall, this subject opened a lot of interesting topics to me, and gave Electronics Engineering a new light. I’m amazed by how much we can contribute to the scientists, doctors, and people in the medicinal world. The most important part of the subject though is Ethics. As engineers, we should prioritize the privacy and safety of the devices we create, whether they be physical or psychological.
