Biomedical & Electrical Engineering

Bioengineering

Biomedical engineering is the field in engineering that focuses on inventing new machines and devices to improve health care for people. The field incorporates engineering, design, and technology concepts to solve problems in the medical and biological fields.

Electrical engineering

Electrical engineering focuses on the use of electronic devices, using components built together to form circuits, performing a given task. Electrical engineers use currents, resistors, capacitors, and other various pieces of electrical equipment to develop effective hardware.

Our Work

Series

A series circuit is a type of circuit where the current takes one path as opposed to branching out into multiple places. Seen above is a series circuit we designed on a breadboard where one switch and a battery pack is being used to power two LEDs. It is a series circuit since there is one path being taken in one series.

Parallel.mp4

Parallel

A parallel circuit is a another type of circuit where unlike a series circuit, the electrical current branches in to multiple paths. In this type of circuit, the components have their own path of electricity, so the voltage is the same.

Circuit Lab

College Admission Requirments

At the beginning of our project, we were given a task to create a logic circuit simulating a college admission process. Using OR and AND symbols, this logic circuit makes it easier to find admission requirements automatedly, allowing admissions officers to shortlist potential students.

For our Week 1 project, we had to create a circuit to help detect coronavirus symptoms. This would alert a user after detecting three symptoms; a dry cough, a high temperature, and low oxygen levels. Looking at this, a patient would be marked 'risk-free', if they do not have any symptoms, displaying a green LED light. If only one of the symptoms is prevalent, the light would turn yellow. However, if all the symptoms are visible over a period of time, the LED will turn red, sounding an alarm.

Simulated Coronavirus Alarm System

Before creating the actual coronavirus detection system, we simulated the circuit digitally, first simulating the alarm system, and then simulating the logic for the requirements that would trigger each LED color or alarm. On the right is the alarm circuit on CircuitLab, using a 555 timer IC and resistors to activate noise in a speaker.

Assembling the Coronavirus Board

Our design process for constructing the actual Coronavirus testing circuit board was to create the alarm circuit and the timer circuit separately, and then hook the alarm circuit up to the logic circuit while the logic board was being assembled based on the CircuitLab schematic that was created to plan out the board.

This is our completed simulation on Circuit Lab. Notice that it is vast and complicated since it has to encompass four different outputs, and since the red and yellow colored LED's each have three possible conditions for them to light up, simulating all of them and then fitting them into the final simulation with the clock and the alarm took up a lot of space.

Here is a simulation for our coronavirus project. This is the simulation's result when one symptom is present since the yellow light is turning on as seen by the bar at the top. The simulation helped us confirm that the circuit's logic was working correctly and that the right amount of symptoms correlated with the correct LED/alarm output at the end.

Shown above are works in progress as our circuits were being created. The alarm circuit and the first part of the logic circuit are shown on the right.
