High wrist acceleration
WebDec 31, 2024 · The high temporal and intensity resolution of modern accelerometers gives the opportunity of detecting even tiny body movements via motion-based sensors. In this paper, we demonstrate and evaluate an approach to identify pulse waves and heartbeats from acceleration data of the human wrist during sleep. WebBackground and objective: Recently, various algorithms have been introduced using wrist-worn photoplethysmography (PPG) to provide high accuracy of instantaneous heart rate (HR) estimation, including during high-intensity exercise. Most studies focus on using acceleration and/or gyroscope signals for the motion artifact (MA) reference, which ...

Our findings on the high correlation ... WebApr 23, 2013 · Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes increasingly difficult during rotational movements.
WebIntuitively, wrist acceleration will have a more noisy relationship with PA than hip acceleration, because extraneous arm movements can create high accelerations without correspondingly high energy expenditure. A wrist accelerometer will, therefore, record higher overall levels of acceleration than a hip accelerometer .
