Our goal is to design a device to monitor skin color changes during hot flashes, which could be used to provide the objective measurement needed for therapeutic drug testing for menopausal women. The device is to be capable of discerning color changes while remaining small and at a low cost.
Weíre finishing testing and preparing our poster.
|Week||Reporting Period Beginning||Activities|
|1||January 25||Formed our team and chose our project.|
|2||February 1||Met with our advisor and client in order to review the main objectives of the course. Because this is a continuing project, we also researched last semesterís work.|
|3||February 8||Had a brainstorming session and obtained the materials from last semesterís group.|
|4||February 15||Produced a PDS, began to design an improved circuit, and tested the circuit with the red LED in the instrumentation lab.|
|5||February 22||Constructed two matrices, one based on housing options and one based on material options, We also tested the circuit with the blue LED.|
|6||February 29||Ordered materials, designed tests to find the best LED-to-photodiode angle, and began work on the mid-semester presentation.|
|7||March 7||Performed tests to determine the best component angle, performed our mid-semester presentation, and began work on the mid-semester paper.|
|8||March 14||Spring BREAK.|
|9||March 21||Reviewed what each team member has accomplished and is responsible for, reviewed mid-semester presentation and paper.|
|10||March 28||Built Circuit and tested paint samples. Compared samples to actual skin, not a very big difference between normal and red skin.|
|11||April 4||Optimized circuit for our membersí skin tones using a potentiometer to find the best resistor values.|
|12||April 11||Began testing and purchased new equipment due to LED burnouts.|
|13||April 18||Finished Housing and optimized resistor values for best redness detection and LED lifespan.|
|14||April 25||Completed testing and prepared poster.|
