Abstract

Abstract. Measuring vital body signals is essential to measure basic body functions, prevent misdiagnosis, detect underlying health problems and motivate healthy lifestyle changes. Vital body signals are measured at the fingertips because the skin is thin, and the blood vessels are transparent. Visible light is passed at the fingertips, and the pulses generated are still acceptable on the outer nail. However, the body's vital signal measuring device continuously attached to the fingertip causes discomfort to the user. Therefore, in this study, it is proposed to measure the body's vital signals in other body parts. The wrist was chosen to be attached to the body's vital signal measuring device because the measuring device attached to the wrist allows it to continue to be used. This study aims to measure the body's vital signals, especially heart rate, on the wrist so that the correlation level of the measurement data is known. The main contribution of this study is built an electronic system to measure vital body signals, especially heart rate at the wrist with the help of the MAX30102 sensor that uses visible light with 650 - 670 nm. The MAX30102 sensor, which uses visible light with 650 - 670 nm, was selected for measurement. The ratio of the light reflected through the fingertips compared to the wrist. The result of measuring the heart rate signal on the wrist is in the form of a relatively flat wave so that the data sharpening process is carried out using the detrend method. The results showed that the measurement of heart rate signals at the wrist and fingertips of 15 respondents had accuracy 85%. The accuracy value shows that the data from the heart rate signal at the wrist is closely correlated with the data from the measurement of the heart rate signal at the fingertips. Therefore, measurements of heart rate signals, usually performed on the fingertips, can also be performed on the wrist. From the test results with a strong accuracy, measurements are always taken when the hand can measure the place to measure vital signals, which is usually done at the fingertips.
