A portable and low-power device is a great importance to heart-rate (HR) monitoring in medical practices. Due to usage electrode in contact with patient’s body, nowadays Electrocardiograms (ECG) lead to discomfort for patients. Meanwhile, the another device such as Pulse Oximeters only give the HR numbers, without the displaying of signal, so that it can’t used for importance of the bio-signal analysis. In this paper, the optical and USB-powered device to the HR monitoring has been designed and developed. The process of monitoring was carried out based on the detection of the optical absorbance of blood vessels due to heart’s pump activity in fingertip’s patient. In addition to as communication to a personal computer (PC), USB system was also used as a component to provide the power for the device. The programmed software was used to generate the spectra and determine the HR of the obtained signal. Twenty of measurement data of healthy volunteers, aged 19 to 57 years were obtained and validated by a commercial Pulse Oximeter. The correlation analysis and Bland-Altman plot show that the HR measured by both devices are positively correlated and most of their differences within the limitation of confidence interval.
