A 58 nW ECG ASIC With Motion-Tolerant Heartbeat Timing Extraction for Wearable Cardiovascular Monitoring [PDF]

, 2014
An ASIC for wearable cardiovascular monitoring is implemented using a topology that takes advantage of the electrocardiogram's (ECG) waveform to replace the traditional ECG instrumentation amplifier, ADC, and signal processor with a single chip solution.

Heart Rate Estimation from Remote Photoplethysmography Signal

International Journal For Multidisciplinary Research
Remote photoplethysmography (rPPG) enables noncontact heart rate estimation from facial videos by analyzing subtle color changes correlated with blood volume pulses. However, rPPG signals are often contaminated with motion artifacts, illumination noise, and facial expression changes.

Estimating Blood Pressure from Photoplethysmogram Signal and Demographic Features using Machine Learning Techniques

, 2020
Hypertension is a potentially unsafe health ailment, which can be indicated directly from the Blood pressure (BP). Hypertension always leads to other health complications. Continuous monitoring of BP is very important; however, cuff-based BP measurements

BVPNet: Video-to-BVP Signal Prediction for Remote Heart Rate Estimation

2021 16th IEEE International Conference on Automatic Face and Gesture Recognition (FG 2021), 2021
In this paper, we propose a new method for remote photoplethysmography (rPPG) based heart rate (HR) estimation. In particular, our proposed method BVPNet is streamlined to predict the blood volume pulse (BVP) signals from face videos. Towards this, we firstly define ROIs based on facial landmarks and then extract the raw temporal signal from each ROI ...

A robust neural network for privacy-preserving heart rate estimation in remote healthcare systems

Healthcare Analytics
In this study, we propose a computationally-light and robust neural network for estimating heart rate in remote healthcare systems. We develop a model that can be trained on consumer-grade graphics processing units (GPUs), and can be deployed on edge ...

DistancePPG: Robust non-contact vital signs monitoring using a camera

, 2015
Vital signs such as pulse rate and breathing rate are currently measured using contact probes. But, non-contact methods for measuring vital signs are desirable both in hospital settings (e.g. in NICU) and for ubiquitous in-situ health tracking (e.g.
