Week 1 for BioVest:

This week my job for the biovest was to look at previous designs for this shirt that have already been made or when simple just design ideas. There have been many different ideas for this. I found that under armor made a smart shirt that can measure G-Force and Heart Rate.

The People at under amour call it the bug and it measures skin surface temperature, acceleratometry in 3 different directions, heart rate, and respitory rate. We may consider purchasing this device and or finding out how it works and what sensors that they use to acquire your readings.

In other shirts there were too many wires like in the lifeShirt as shown in the picture below

Plus there is also a giant remote to it that would get in the way while one worked out. In our Biovest we are looking to cut down on the number of wires and accessories that come with it. It would be ideal to be able to send the data to one's phone by syncing it up. This can also be done by taking another look at the Under Armour one it has it's own mobile application.

By looking at the LifeShirt I found similar produce that can be used individually like the Beddit Pro, the Equivital EQ02, the NOX-T3, the BioRadio, the Vivosensor, the Actiwave Cardio, the Actiwave Recorder ,the Smartex WWS, the Nonin 3150, the Onyx II 9560, the Pro-Dairy, and the Biovotion VSM.

The most important ones to use might be the:
 * The Equivital EQ02
 * The NOX-T3
 * The Vivosensor
 * The Smartex WWS
 * The Nonin 3150
 * The Pro-Dairy
 * The Biovotion VSM

Most of those sensors just measure the same vitals like heart rate so if we purchased maybe multiple ones we could get a lot of vitals. Also we have decided to change the original shirt from a short sleeve Under Armour to a long sleeved under Armour. This design will give us more room to work with and more surface area for use to possibly put another sensor on. We have also considered getting a watch that measures blood pressure or heart rate and to sew it into the shirt which would be perfect for a long sleeved shirt. There are many watches that can read ones vitals. For example there is many at CVS. The already created watches would have a display built into them so we would not need any wires or cords that connect to a computer so that is a very high idea on our list.

This article was helpful and shows another way we could design the shirt with the wires in the back or some of the sensors in the back of the shirt. Also the sensors seemed to of gone all over his body which might need looking into because the smart shirt looked like it had smart fabric in it. Smart fabric also know as E-textiles are fabrics that enable digital components to be embedded in them. Which means that a sensor could be embedded inside the Smart fabric.

We could also sew some sensors into the shirt but that would be tedious and might cause discomfort to the one wearing the shirt because once it is inside the shirt i cannot be moved for comfort. I believe our biggest problem will be making the shirt comfortable for someone to wear and having a small amount of wires.

Biovest Week 2:

e-Health Platform V2.0 is a good way to get some biometric results. It can measure 10 things pulse, oxygen in blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG), glucometer, galvanic skin response (GSR - sweating), blood pressure (sphygmomanometer), patient position (accelerometer) and muscle/eletromyography sensor (EMG). The e-Health is a shield for arduino that was released by Cookinghacks.

The data will be recorded using these devices that hook up to the arduino: http://skin.cdn-libelium.com/frontend/default/cooking/images/catalog/documentation/e_health_v2/e_health_sensors_small.png

Data can be sent to the Cloud in order to perform permanent storage or visualized in real time by sending the data directly to a laptop or Smartphone. iPhone and Android applications have been designed in order to easily see the patient's information.

Another solution I found was: http://www.seeedstudio.com/wiki/images/thumb/9/9c/Heart_rate_ear_clip_kit.jpg/400px-Heart_rate_ear_clip_kit.jpg

Code for this Arduino is already made Then attach the arduino to the back and have the a wire attached to the finger of the patient.

Biovest Week 3:

This week was about ordering new material and start putting things together. We got the perfect shirt for our design needs. We will put the shirt on someone and then draw wear the sensors will be so this shirt will just be a prototype. The sensor will be ordered shortly. This week me and my partner have been talking about cost and how we shall both pay for the necessary materials because with any other materials we cannot go on.

We be careful where we put the sensors to place them on the some of the best spots to measure vitals but also comfortable spot. This will take a lot of studying but for the pulse it was most likely going to be on the wrist. We would get a strap that was much longer and wider and have it attached to the sensor. We will find out more information on the other vital readers.

We will have to design the click to hold the arduino, also we found out that it would be very use to use an arduino mini so it wouldn't take up add much space. We found out that the most conveint place to put the arduino is on the side of the user so it does not get in the way of a person. If a person were to do sit ups then if the arduino was not the back then it might get irritating or possibly break. The sensor might cause a problem if the side of the user is being worked out.

BioVest Week 4:

This week was meant to find the find the dimensions of all our arduino Micro 48mm by 18mm. We now know the best place on the shirt is on the side. Exactly where we diagramed it in our

http://arduino.cc/en/uploads/Main/ArduinoMicroFront_450px.jpg

This packs the same amount of power as a normal but is much lighter that the normal arduino so it shall not bother the user. The shirt should be a medium sized under armor shirt. With that it is not too big or too small we need it to be skin tight so it more accurately reads the vitals. We shall sew a small pocket onto the shirt so the arduino can be placed into the pocket this way it can be taken out for a more efficient wash because the arduino won't be connected to the shirt. We will also make a flap on top of the pocket so that it will secure it from falling out of the pocket this way it can be removed and placed in simply by opening the flaps.

Also we have thought about getting a water proof case to put the arduino in just in case the user of the shirt puts it in the wash it is fine. For this water proof case we would need a strong material that would be able to protect the arduino in the dryer where it could be bouncing all around. It also should be a little bit of a tight fit because if the arduino micro has room to move it still has the chance of getting broken. The material might need a hard exterior wall yet have a soft and cushioned interior wall because it needs to protect the arduino from moving. Also the exterior should not have edges really one because it would get in the way of the user and make them feel uncomfortable because something sharp is poking them in the side of their shirt and reason number two is because if it is sharp enough then it could possibly make a hole in the shirt and this hole would possibly be big enough that the arduino and it's case fall out. The flap should be dimensioned at 50mm by 20mm.

The shirt will have places where the wire gets trapped so that it isn't all over the place and is much more contained. Before the design was faulty because it would have loose wires that could get caught on something and either harm you or break and ruin the product.
