黑色素與血壓檢測演算法開發暨系統平台實現

Abstract

隨著近年來醫美技術進步，投入美容醫療的人越來越多，其中使用美白治療的人更是逐年攀升，而鑑定美白產品使用成效不外乎以主觀方式觀察，但主觀觀察結果常因人而異，因而造成了不準確，而一般人若想得到客觀的黑色素數據又必須至美白診所，此部分造成了使用者不便及麻煩。 除此之外，儘管近年個人醫療器材普及化，生理資訊如心跳、血壓皆可自我監控，但壓力式血壓計所造成的不適感始終沒有獲得良好改善，因此，一個準確、舒適的個人醫療器材是迫切需要的。 基於以上所述，本論文利用光學量測方法研發一套創新量測平台，利用皮膚組織對不同波長光的吸收及散射特性評估使用者黑色素濃度，其中本論文更提出一套新的補償方式，考慮光對表皮層及真皮層的交互作用，使得黑色素量測更加準確。 此平台相較於其他市面上儀器具低耗能、面積小且多用途的優點，除了量測使用者黑色素濃度外，此平台更可獲得使用者心跳以及血壓資訊，使用者只需量測臉部，就可獲得這些生理資訊，讓使用者不僅在測量美白效果時，同時還能監控個人生理資訊，達到美麗與健康的結合。

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.
