Biomedical Electronics

This work includes several independent projects that were completed for various reasons over the course of my undergraduate education. The device pictured in the lower right section of the screen was built during the Biomedical Engineering Design and Manufacturing I course offered Fall 2017. This device is a motor drive circuit (pictured without the motor), and it was designed to control a syringe pump.

The device pictured in the upper left section of the screen is the patient interfacing half of an ECG, and it was built during the Biomedical Instrumentation course offered Spring 2019. This ECG is

battery powered and has an on-board optical isolator to ensure the safety of the patient using the device. Further, it connects to medical grade ECG electrodes on one side and higher voltage instruments on the other side. This configuration permitted the measurement pictured on the oscilloscope in the lower left section of the screen. The signal pictured there is a single cycle of the electrical activity of my heart recorded with the ECG pictured above.

Finally, the device pictured in the upper right section of the screen was built during the Biomedical Microcontroller Applications course offered Fall 2019. This device is multipurpose and was designed to survey all the capabilities of a modern microcontroller.
