Key result
Novel ECG and PPG wristband matches E2-KIT reference device for peak inspection accuracy.
Why the study?
A new method for real-time ECG and PPG measurement on the wrist for daily health monitoring was proposed to improve convenience and accuracy.
Does a wristband-type vital sign acquisition device accurately measure ECG and PPG compared to a reference E2-KIT?
Does a wristband-type vital sign acquisition device accurately measure ECG and PPG compared to a reference E2-KIT?
A newly proposed wristband device can measure ECG and PPG with comparable peak detection accuracy to a reference E2-KIT device.
In this study, we proposed a new method that can be measure ECG (Electrocardiography) and PPG (Photoplethysmography) in realtime on the site of the wrist for check the state of health in daily life. For convenience measurement of ECG the lead Ⅰ method was used on the wrist, and omit the reference junction ECG I was measured in the right hand and the left hand of the potential difference. Then the measured electrocardiogram was amplified by the differential amplifier and the signals were passed HPF, LPF, and BPF filters. For removing the PPG’s noise from the Motion artifact and temperature, we apply the reflective photoelectric volume pulse wave measurement method using green LED as a light source. The circuits was designed to be able to check the waveform using higher active amplification method at weak signals. For the validation of our device, the measured signals were compared with E2-KIT on same time. The results shows that the error does not exceed the maximum one, most of the data is confirmed to be issued Peak inspection of the same number.

Kim et al. (2016) studied this question. Wrist band type vital sign acquisition device (ECG and PPG) vs. E2-KIT was evaluated on Signal accuracy (Peak inspection). A novel wristband device for real-time ECG and PPG measurement yielded peak inspection results comparable to the E2-KIT reference device.
