Project Overview

A skin color monitor that records color changes every 10 seconds that occur during hot flashes, which could be used to provide the objective measurement needed for therapeutic drug testing of menopausal women. The device is to be capable of discerning color changes while remaining small (6 x 6 x 2)cm or smaller and at a low cost (under $200). A 525 nanometer wavelength LED will shine light onto the skin and a photodiode registers the change in reflectance due to blood flowing into the skin. This lowers the output voltage by 5 to 7 mV. The changes in the voltage are recorded every 10 seconds. In the future, the device will adhere to the skin in the upper chest region. Also, the circuit will be printed on a miniature circuit board and the electronics will be integrated into the housing.
