Final Project Proposal
Project: BBT Lingerie
Objective: To allow women to track their ovulation in an easier and more stylish way.
A woman would typically track her temperature, using a Basal Body Temperature (BBT) thermometer, in order to find out when she is most fertile in order to become pregnant. The process is described below:
“To measure your BBT, use an older oral glass/Mercury thermometer, or a special BBT thermometer available at some pharmacies. For glass thermometers, shake it down before going to bed, and leave it close by and within reach. As soon as you awake, with minimal movement, put the thermometer in your armpit, next to the skin, and leave it for ten minutes. Record the readings for three to five consecutive days.”

BBT Lingerie is a camisole, worn to bed, with a thermometer build into the fabric near the underarm. When the woman wakes up in the morning, she presses a button on the front part of her shirt (disguised as a lace or flower applique.)
This button turns on the thermometer and allows for the BBT to be taken, before she even moves out of bed (since moving affects the outcome.) The thermometer beeps when done and the reading shows up on the camisole where the woman can read it.

The current devices used for tracking basal temperature are BBT thermometers, which are typically used orally (Fig. 1).
There are thermometers available now that are one-time-use, such as the TraxIt® Wearable Thermometer (Fig 2). TraxIt® Wearable Thermometer is designed to monitor skin temperature continuously. It is thin, flexible piece of plastic made with adhesive. See link for more info. http://www.medicalindicators.com/pdf/Trax-FC-Tech-bulletin.pdf
These kinds of thermometers can take an accurate temperature, and are meant to be, to some extent, wearable (Fig 3).
Mechanics
The device will be built with a very sensitive thermistor. (See image below.) This model is called the NTC Thermistor: Type MC65. It is an insulated lead interchangeable chip thermistor.
