The sensor records the periodic changes in airflow temperature brought on by breathing cycles that result in the exhalation of heated air and the inhalation of cool air.
The creation of the sensor and algorithm for determining the user’s breathing frequency is the main focus of the study. While this sensor would be appropriate for usage in an industrial setting, it does not allow for the evaluation of respirator fitting or filter clogging level.
Although the sensor provides a comfortable and minimally invasive method of tracking breathing frequency, it is linked to the user’s ears and placed beneath the nostrils, making it unsuitable for usage while they are working.
The Global Al Virtual Breathing Sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The development of an artificial intelligence (AI) model to identify PD and follow its evolution using signs of nighttime breathing. On held-out and external test sets, the AI model can identify PD with an area-under-the-curve of 0.90 and 0.85.
The models can detect breathing through radio waves that reflect off a person’s body while they are sleeping, enabling touchless assessment of PD in the home.
Their study provides preliminary evidence that the AI model may be helpful for risk assessment before clinical diagnosis and shows the viability of objective, noninvasive, at-home evaluation of PD.
A breathing belt worn on the person’s chest or abdomen can be used to gather one night’s worth of breathing signals, which the system uses as input.
Without the use of wearable technology, the breathing signals can be obtained by sending out a low power radio signal and observing its reflections off the subject’s body.
The fact that this model learns the auxiliary job of anticipating the subject’s quantitative electroencephalogram (qEEG) from nocturnal breathing protects the model from overfitting and aids in the interpretation of the model’s output.
Either a breathing belt worn by the subject or radio signals that reflect off their body while they are sleeping are used by the system to collect nocturnal breathing signals.
It analyses respiratory signals using a neural network to determine whether the subject has Parkinson’s disease (PD), and if so, determines the degree of their PD in line with the MDS-UPDRS.
