Problem Statement
Our group will be working on the Bioengineering project. We hope to create a vest with a device in the middle, which is able to measure your pulse, or breathing rate. If the device detects that your pulse is too high, or that you're breathing too fast, it will light up red or blue. Plus, we hope to add a temperature aspect to the device. If it can sense that your body is too cold, the device will warm up your body by sending heat waves. Our group will create the concieve phase.

Project Plan
In the first week, we plan to do benchmarking or research on other products, and conducting a survey on what other people think about our project.

Week 1 Narrative
This week we will start our research for our product. First, we will look at other products that have been on the market and determine their I went to the Howard Community College athletic center and took a quick survey of 30 people who were working out, sitting at the front desk, and random students who were just hanging out at the tables. Only 36% of them had said they would use a product like this, frankly because they simply wouldn't need it, and if they would, it would need to be light weight. Also, 80% of them had said that they would rather the device be on the arm than the chest, because it would feel too "awkward" for them. Plus, because this is a simple device, people would not be likely to pay much for it.
 * Weaknesses
 * Strengths
 * Price
 * Weight
 * Durability
 * Reliability

This matches up correctly with our CDIO discuss page because we have finished the benchmarking and research aspect of the project. https://en.wikiversity.org/wiki/User:Medelen8/ENES100/Bioengineering_Project_Conception

Week 2 Narrative
So far our project has been approved. However, we need to work on making our measurements more accurate. This week I have focused on specific research based on the functionality of our device. I researched an algorithm for Respiratory rate so our device will function with less percent error. Respiratory rate is defined by the number of breaths within 60 seconds. This is usually measured when a person is at rest, by counting how many times their chest rises. There are various normal ranges for different ages, we will focus on: This is because our device will be oriented to people who are more active, such as athletes, and the elderly.
 * 12 yrs and up, 15 - 20 bpm (beats per minute)
 * 16 yrs and up, 12 - 16 bpm

Minute Volume
Another important parameter to consider is Minute Volume, which is the volume of air inhaled and exhaled within a persons lungs. One will experience hyperventilation (low CO2) if there is too much air volume within his/her lungs, and hypoventilation (high CO2) if there is too little air within his/her lungs. The normal air capacity is 5-8 liters, but will fluctuate during exercise. Overall, there are 3 methods of measurement: The Wright Respirometer is expensive, around 1400$; plus, using the equation will require a spirometer (around 8-10$) to measure tidal volume. Still, the equation is more practical on our hands because we can embed the equations into our code and it's cheaper. Measuring minute volume is important because it will make the device determine if our levels of CO2 are too high or too low, which fluctuate during exercise. I am a little disappointed, however, that I spent the majority of my time studying minute volume, when there are many other ways to measure Respiratory Rate. I definitely would've received more information if I had. Overall, i wasn't able to define an effective "algorithm" for respiratory rate, but was able to find an accurate way in measuring it with minute volume.

 * This equation uses different variables, and also needs a spirometer to measure tidal volume. It's less practical because the variables require more mathematical analysis Minute Volume 2.jpg

Week 3 Narrative
During Week 2 I conducted a considerable amount of research on coming up with algorithms for respiration rate. This research lead to Week 3, where I looked into sensors. Luckily, we were able to find an Arduino, called the e-health sensor 2.0, which is specifically used for medical purposes. This platform includes a total of ten sensors on the Arduino. I looked into the Airflow sensor feature. It uses two prongs placed in the nostrils and a flexible thread placed behind the ears; overall it's comfortable and easy to install. I saw that a graphics LCD is able to show us the respiratory rate and bpm. Not only is this compatible with Arduino, but also Raspberry Pi. Next week, our group will look at high end architecture.

Week 4 Narrative
''Describe in detail what you did for your team during the week (and weekend). Link to any CDIO documents you are working on. Compare your task (from CDIO discuss page) with what you actually did.''
