Summary/Discussion

This product is inaccurate in its readings when compared to those of an oral thermometer. As shown by the t-test, the t-value is far lower than the standard measure of p>0.05, which means that there is a statistically significant difference between the oral thermometer readings and those of the tested device.

Reasons for this could be experimental error, but is more likely due to several key design flaws.

The first major design flaw was that the sensor needed to be constantly readjusted and reattached, which could have easily been solved by creating an armband or some such support structure that would keep the sensor in place.

A second flaw is that this device has an apparent maximum temperature reading, which is far below that of the average human body. This flaw is more of an error in production or creation of the device.

The third and final flaw is the consistency in which the device read temperatures. Our subject went through several different stages of motion such as walking, jogging, stair-climbing, and sitting in a chair, yet the device read the same temperature in all stages. This flaw leads to a conclusion that the device is very reliable, but is not accurate when compared to the conventional oral thermometers.

Target Population and Need

The "ThermoBand" temperature-recording device targets athletes/active people in need of an easy way to measure their body temperature. We want to help athletes take care of their bodies by providing them with accurate body temperature data while they're performing various physical activities including running, lifting, cycling, etc. Most body temperature sensors are big, inaccurate, inconvenient and require their own personal device. With our '"ThermoBand", taking and recording temperature will be easier and more accurate than ever.
