Abstract

Controlling and monitoring of Low-density lipoproteins (LDL) and High-dens ity lipoproteins (HDL) of the total cholesterol level is essentially important for preventing an elevated risk of cardiovascular disease such as coronary heart disease, stroke, peripheral vascular disease, diabetes and high blood pressure. The purpose of this project is to carry out a non-invasive method for measuring cholesterol level and develop a hardware prototype for a non-invasive cholesterol meter. Heart rate sensor is used for detecting and determining the cholesterol in the blood. Cholesterol levels can be measured in a circulating bloodstream within a subject, by obtaining light absorbance data at about 1720 nm +/15 nm, or at about 2300 nm +/15 nm, in combination with a closely spaced reference wavelength, the latter being relatively insensitive to cholesterol content. Android apps has been developed to display and store the data into cloud server. The percentage of accuracy is 97% with compared to the existent device. Percentage difference between new non-invasive and invasive device is 0.6 to 3.1% and still acceptable.This innovation has created an alternative in getting painless cholesterol reading and reducing the usage of cholesterol strips.
