Device for Melanin / BP

**Correlations of experiment results can be seen in first two screenshots(melanin and heart rate).

With the advance in cosmetic medical technology in recent years, more and more people get cosmetic medical treatments, especially skin whitening treatments. Nevertheless, people usually assess the effect of skin whitening products in visual, which is subjective and will be different from each person. To acquire the value of melanin concentration objectively, people need to go to cosmetic medical clinics. This will cause inconvenience to people.

Although personal medical devices which can monitor one’s heart rate and blood pressure have been popular and available to people, sphygmomanometers still cause uncomfortableness and haven’t been improved until now. Therefore, an accurate and comfortable personal medical device is necessary to be developed.

From reasons above, this thesis develops a novel evaluation platform based on optical assessment methods, which employ different absorption and scattering properties to different wavelengths of light in human tissue to obtain melanin concentration. Moreover, this thesis proposes a new method that compensates the interaction between epidermis and dermis to acquire the melanin concentration more accurately.

The novel platform designed in this thesis is lower-power, smaller and more functional when comparing to other conventional devices in market. It can not only evaluate the melanin concentration but acquire heart rate and blood pressure. People only need to measure their cheeks and physiological information can be obtained. This will let people monitor their personal physiological information and make sure the effect of skin whitening products simultaneously, which performs the combination of beauty and health.
