XeThru sensor provides quality data comparable to Polysomnography medical sleep monitoring study

Sleep tracking nowadays has definitely been gaining steam in the health monitoring and technology world. Monitoring details on our sleep quality and habits can help us improve our lives in general and indicate sleeping disorders that are potentially dangerous.

Today’s market is flooded with health trackers, gadgets, mobile sleep apps, all promising to offer the capability to track one’s own health in the comfort of their home. Even though these products are becoming more and more personal and customized to one’s lifestyle, the vast majority of them are based on contact. Novelda takes pride in offering a monitoring technology that is completely non-invasive. In other words, users can practically forget that there is a tracking sensor on their nightstand or in the ceiling above their bed, actively monitoring their respiration and movement during sleep.

Our confidence in our monitoring solution took us one step further; we wanted to challenge our technology and compare it to the industry’s gold standard in sleep monitoring, called polysomnography or PSG. The comparative study that was conducted at Novelda, included 13 test subjects fitted with PSG equipment monitoring their sleep. Each test subject was in addition monitored by a XeThru sensor measuring respiration and movement throughout the night. The goal of the study was to validate the accuracy of the XeThru sensor while monitoring respiration rate and movement against the esteemed polysomnography.

Our latest whitepaper XeThru Sleep Monitoring: A Polysomnography (PSG) Comparative Study, reveals the results of the study. The XeThru sensor is indeed able to measure the respiration rate with high accuracy, detect small body movements during sleep, and overall deliver quality data comparable to polysomnography, the medical gold standard in sleep monitoring (as seen in the figures below).
