A combined method to reduce motion artifact (MA) and power line interference (PLI) for wearable healthcare system is introduced. The proposed method has a block for the reduction of MA using measured electrode-skin impedance as a reference signal and a block for the cancellation of PLI using mixed-signal feedback to relax the dynamic range requirements of components in the forward path. The measured...
Heart rate monitoring has been a significant topic of interest in the areas of healthcare, sports and gaming. Compared to locations such as the neck, ear, or chest, the wrist is a convenient measurement point, as the measurement technology can be integrated into a wristwatch. However, key technical challenges exist, namely a small physiological SNR and large disturbances due to motion artifact. This...
Driven by the growing aging population, prevalence of chronic diseases, and continuously rising healthcare costs, the healthcare system is undergoing a fundamental transformation, from the conventional hospital-centered system to an individual-centered system. Current and emerging developments in wearable medical systems will have a radical impact on this paradigm shift. Advances in wearable medical...
In this paper, a real-time, wearable and motion artifact reduced health monitoring device is represented. A finger band, wearable health monitoring device, is consists of photoplethysmography (PPG) sensor, 3-axis accelerometer, microprocessor and wireless module. The PPG sensor acquire distorted heart beat signal due to motion artifact. The finger movements are detected using the accelerometer, and...
