SleepMove Device

SleepMove is a wireless device that is capable of collecting data from various types of piezoresistive sensors deployed in a network to improve the dynamic range of sensor arrays and satisfy the requirements for feature detection and extraction from the collected neuro-motor signals. The network of extremely thin (1mm) sensors are placed underneath the bedding to allow for a flat and unobtrusive sleep surface. Advanced wireless system design addresses the main challenges that include, sensor sensitivity/selectivity, interference, and most importantly low signal to noise ratios associated with brain research applications. Hardware and software integrate movement and respiration variability using a fast-time, neuro-motor bout detection algorithm. This unit wirelessly transmits the data to the central processing unit that can be placed along-side the patients’ bed.

Neuroscience Algorithm

SleepMove device comprises a suite of algorithms that replicate standard Sleep-Wake measures, i.e. WASO (wake after sleep onset), time in bed, sleep efficiency, number and duration of sleep and arousal events, that have been confirmed with commercial actigraphy, and polysomnography (PSG).

Sleep Movements (SM). In clinical studies with brain-injured patients, proprietary algorithms detect high frequency sleep movements (2’ periodicity) that correlate with sleep disorder and sleep fragmentation, and are reflected in impaired cognitive performance.
Respiration(RR). Respiratory inspiratory/expiratory rate and amplitude are tabulated continuously throughout the night by the SleepMove system. Respiratory measurement integrity matches clinical thermistor and plethysmography analogues. Proprietary algorithms for sleep disorder integrate SM and RR events to provide markers of autonomic and hypoxemic features of sleep.
Obstructive Sleep Apnea (OSA). Our software is designed to detect abnormal breathing including periodic, gasp and pauses to estimate the AHI (apnea-hypopnea index) without plethysmography (tight belts on the chest and abdomen). Verified medical grade technology permits home testing for OSA.
