Abstract Background and Objective Sleep is an important part of our life. That importance is
highlighted by the multitude of health problems which result from sleep disorders. Detecting …

Apnea is a sleep disorder that stops or reduces airflow for a short time during sleep. Sleep
apnea may last for a few seconds and happen for many while sleeping. This reduction in …

Unobtrusive home sleep monitoring using wrist-worn wearable photoplethysmography
(PPG) could open the way for better sleep disorder screening and health monitoring …

Automatic sleep stage classification with cardiorespiratory signals has attracted increasing
attention. In contrast to the traditional manual scoring based on polysomnography, these …

Background Patients with COVID-19 have increased sleep disturbances and decreased
sleep quality during and after the infection. The current published literature focuses mainly …

Abstract Study Objectives: To compare the accuracy of automatic sleep staging based on
heart rate variability measured from photoplethysmography (PPG) combined with body …

We describe a system for the evaluation of the sleep macrostructure on the basis of Emfit
sensor foils placed into bed mattress and of advanced signal processing. The signals on …

We present a method for measuring beat-to-beat heart rate from ballistocardiograms
acquired with force sensors. First, a model for the heartbeat shape is adaptively inferred from …

Polysomnography (PSG) is considered the gold standard to assess sleep accurately, but it
can be expensive, time-consuming, and uncomfortable, specifically in long-term sleep …

We studied a novel non‐contact biomotion sensor, which has been developed for identifying
sleep/wake patterns in adult humans. The biomotion sensor uses ultra low‐power reflected …
