Mean Temperature: Gold Standard: 96.64716 Dg F
Mean Temperature: Spree Headband: 95.53086 Dg F
Mean Heart Rate: Gold Standard: 98.08977 BPM
Mean Heart Rate: Spree Headband: 99.08911 BPM

We used A T-Test to determine Significance between the Gold standard and the Spree Headband.
T-test value for Temperature: 4.55337E-26
Heart Rate: .636659
This direct correlation did not relate to the Temperature aspect of the two devices because the Pearson’s values was further away from 1. THis means that they will increase and decrease differently.
The T-test value for Heart Rate was greater than .05 meaning that there is significant difference between the Spree and the Golden Standard. The difference shows that the Spree was insufficient at taking heart rate.
The T-test value for Temperature was much smaller than .05 meaning that there is significant correlation between the Spree and the Golden Standard. The correlation shows that the Spree was sufficient at taking Temperature.
As we began gathering data for our lab we noticed quite a few critical flaws with the Spree headband. One of the major design flaws that we found was that the Spree headband uses a 1-4 system to evaluate body temperature. The problem with this is that it is extremely inaccurate and was probably designed this way because the Spree headband cannot accurately read temperature to an exact number. Another flaw was that the bluetooth connectivity was constantly failing. Having to constantly try to reconnect the bluetooth component is not ideal for someone who wants accurate readings while they are working out. A design flaw we noticed when we went outside was that the temperature reading for the Spree was influenced by the outside temperature. The spree should accurately read the subject's temperature and not be influenced by the outside temperature. The final flaw we recognized was that at times the Spree would show that the subjects heart rate was zero. Since this was not the case and our subject was in fact still alive, this should be considered a major flaw. In order to fix these flaws the Spree will need to advance its technology for bug fixes and more accurate readings.
The strengths of the device are that it is user friendly, computes certain data accurately, and has a strong battery life. Another strength to consider is that the headband is lightweight and does not present itself as a major distraction when participating in exercise.

Target Population and Need
The target population of the device is mainly the athletes due to the extensive exercise they make that can make them susceptible to develop severe diseases, or even can lead to death. This device can help them monitoring their blood glucose levels, oxygen saturation, proteins, Heart rate, and Blood pressure. There are already 120 sports-related deaths of young athletes in 2008-2009, 50 in 2010, and 40 in 2011.
There is a great demand for this device because athletes have a great risk of developing low blood sugars, both during and following exercise, and the body will not be able to perform its normal, rhythmic functions with low blood glucose level. Additionally, athletes also have high risk of developing low blood oxygen level due to the excessive exercise they do, which can further lead the organs like the heart or the brain to be hypoxic, meaning that they can not function due to insufficient Oxygen supply. Most Athletes today want to know their oxygen levels, heart rates,and blood pressures, and now they have the ability to monitor their glucose and protein levels as well to further tailor their workouts.
Device Design: Smart5kin is designed around a non-dissolvable biomesh that incorporates sensors across its face to measure protein levels, glucose levels, oxygen levels, heart rate and blood pressure. Implanted directly under the skin in a minimally invasive, outpatient procedure, this device monitors the aforementioned bioindicators in the body, and by simply placing a phone with our app on top of it, the bluetooth transmitter in the mesh sends all of your bioindicator data directly to your mobile device. Power Source- This device is self powered through the internal electrical field that naturally exists inside the body, captured by a conductive wiring that spans the length of the mesh. There is no need for a battery to store this energy, as it is a constant flow of power from body to device, and this device is constantly using up the power to measure the body’s functions. Interface- This device has a micro bluetooth transmitter, which is one of the patented technologies of our company. By simply placing a bluetooth compatible mobile device on top of your Smart5kin, your raw bio-data is instantly transferred to your phone, and a report is given in seconds as your phone interprets this data with our patented app.
Biomesh- The device itself is made out of a highly flexible, very resilient and completely inert modified Teflon strand material, molded into a fine net shape, and ingrained with our Patented Smart5kin conduction system. This Smart5kin is coated in growth factors that promote the growth of blood vessels in and around the sensor to aid in detection of bioindicators. This is the basis for both powering the system, and transferring data via our micro bluetooth transmitter.
Heart Rate Sensor- This device works with the same technology found in your common Electrocardiogram, just minimized to fit right under your skin. This device measures the electrical signals from the heart by monitoring the electrical currents that jump from each section of net to the next. By detecting the electrical signals directly from the heart from right under your own skin, your heart rate will be measured with accuracy never seen before.
Blood Pressure- A unique aspect of Smart5kin is the ability to measure your blood pressure during activities. By implanting this device right under the skin, Smart5kin lies in a very vascular area. From this positioning, the device measures the expansion and contraction of blood vessels, and reads out a systolic and diastolic blood pressure without the need for clumsy cuffs and other devices.
Glucose/Protein/Oxygen levels- This device also makes use of its positioning inside the body and very close to vascular areas to measure protein, oxygen and glucose levels. Since the device is internal, and vascularized by means of our growth factors, 3 open sensors incorporated into the mesh measure protein, oxygen and glucose levels of the blood that passes over them, giving a constantly updated, extremely accurate reading.
