Lab 3A: “Device Validation”
You have just graduated with your BME degree and have been hired by a start up company called “Suntronic”. They are developing a new body temperature sensor/app for smart phones and want to check out the competition. The latest such device is from RAIING (www.raiing.com) and they claim the device is reliable and accurate. Your assignment is to assess how valid and reliable the device is as well as identify any design flaws by comparing the temperature readings on the device to those of an oral thermometer.
1. Take 5 temperature readings in the lab. One every two minutes using both the sensor and the oral thermometer at the same time.
2. Walk around campus and take one reading every five minutes using both the sensor and oral thermometer at the same time.
3. Return to the lab and take 5 temperature readings, one every two minutes using both the sensor and the oral thermometer at the same time.
4. Enter your results into the Excel spread sheet on black board under your group number.
5. Calculate the mean and standard deviation for both the oral thermometer and sensor.
6. Calculate the correlation coefficient (Pearson’s r) between the oral thermometer and sensor.
7. Run a t-test between the oral thermometer and sensor.
8. Graph all your results.
9. Write a summary of your results including any conclusions you have made from your analysis and summarize any design flaws you have noted during test.
10. Make recommendations as to how you would improve the device.
Vitals Monitor App installed on an iPhone
Setting Up The Device (images on Blackboard):
A. Download the Vitals Monitor from the iPhone Apps store (it’s free).
B. Turn on blue tooth in your iPhone.
C. Press the On Button at the bottom of the device for 1 second to turn it on.
D. Set the temperature to Fahrenheit and the min to 89 degrees and max to 104 degrees.
E. Tape the device beneath the arm pit of one of your team members.
F. Link your iPhone to the sensor.
Note: Make sure the iPhone is always within a few feet of the sensor.
Lab Report 3A due 10/02/13 (through OpenWetWare)

Lab 3B: “Device Development and Marketing”
You have assessed the competition’s (RAIING) device and have decided to move forward on designing your own body temperature sensor. Based on the obvious flaws in your competition’s sensor, design a new sensor. There are two components to this lab. The first is the written component in which you present you design, “data”, and analysis. The second is the commercial that will be shown in class where you market your device to a target population.
1. Identify a target population and need in that population for your sensor.
2. Draw a diagram of your sensor using any graphics program you like.
3. Create a fictitious data set (in excel) showing what you did to test the device.
4. Analyze your data using the appropriate statistics and graph the results.
5. Create a Logo and slogan for your device.
6. Create a 30 second TV commercial in which you market your device to your target audience presenting your compelling data and ingenious design. Use any movie making software you like.
