Problem Statement
''In one or two sentences, describe the project that your group will be working on. Identify what CDIO phase (Conceive, Design, Implement, or Operate) your group will complete in this project cycle.''

Project Plan
Briefly describe your group's plan for the next 4 weeks, including major tasks that will be completed each week.

Week 1 Narrative
For this week, I needed to learn about different ways to measure heart rate. This is a very important component of the BioVest because a person's pulse (measured in beats/minute) can indicate if they are whether they are healthy or need immediate medical attention. It's also a good way to measure your fitness level during or after rigorous exercise.

Locations to Find Pulse: 
 * 1) Radial Pulse: Wrist, just below the thumb
 * 2) Carotid Pulse: Side of the neck
 * 3) Inside of the elbow

A simple way to measure the pulse would be to use something like a heart rate watch, and attach it to the sleeve of the shirt. This way, it would always be in contact with the skin, and in an area where the pulse is strong. An alternative could be to measure the pulse from the neck, where there is the least disturbance from movement, especially during exercise. This may be uncomfortable for some people.

Week 2 Narrative
For this week I needed to figure out how we would incorporate the Pulse Sensor into our the BioVest and attach it to the wrist of the shirt.

The Pulse Sensor is an Arduino based project that is capable of measuring and recording a heart rate. Normally, it is clipped onto your finger, but we want everything to be a part of the shirt, so what I want to do is have it sewn into the sleeve so that the sensor will be touching the wrist at all times.

Possible issues with this design:
 * Keeping wires dry from perspiration
 * Wired may break if stretched
 * Weight of Ardiuno and power source
 * May be difficult to detach when sewn in

To keep the wires from moving freely inside the shirt, we would need to create a long "pocket" for them to run though from the side of the shirt and up through the arm. Since the wires can be detached from the Arduino, whenever the BioVest needs to be washed, the user can remove them through either the sleeve or bottom of the shirt and then put it back though when they are done.

Here is an example of a project similar to ours that uses a headband instead of a shirt, but the overall concept is the same.

Week 3 Narrative
''Describe in detail what you did for your team during the week (and weekend). Compare your task (from CDIO discuss page) with what you actually did.''

Week 4 Narrative
For the final week of our project, we needed to finalize design of the BioVest. Since we are going to use the Pulse Sensor to measure heart rate, I decided that it would be best for us to connect it to a Arduino Micro instead of an ArduinoUno. The Micro occupies less space and is also thinner, so it will fit against the shirt better. In addition to
