## 3 Methods
### The NeuroPredict Platform
#### 3.1.3 NeuroPredict Smart Environment and IoMT Devices  
The data integration methodology used by NeuroPredict starts with the aggregation of heterogeneous data streams. Data gathering inside the NeuroPredict platform is made possible by the implementation of the NeuroPredict smart environment based on IoMT devices. These devices are carefully chosen to accurately measure numerous physiological parameters essential to assessing health problems as well as environmental factors. These real-time physiological and environmental data are regularly gathered and sent to the ICIPRO cloud infrastructure for storage and processing. Data for each monitored patient are either manually input through a form, using the web interface, or acquired by an IoMT device that is either already available on the market or developed in-house. 1. Commercially available devices  
The commercially available devices integrated into the NeuroPredict platform are presented in the following list:  
* The Withings Blood Pressure Monitor Core [67]  
It allows users to acquire blood pressure, heart rate, perform ECGs, and to be used as a digital stethoscope for detecting valvular heart diseases. It provides Bluetooth and Wi-Fi connectivity. * The Withings Move ECG [68] smartwatch  
It performs ECGs, providing access to the recorded signal and the user's heart rate, and it detects arrythmia events like atrial fibrillation events. It analyzes sleep, identifying sleep stages and assessing sleep quality. It keeps track of steps taken, the number of floors climbed, workout activities, walked distances, and burned calories. It provides Bluetooth and Wi-Fi connectivity. * Withings ScanWatch [69]  
Withings ScanWatch performs the same measurments as the Withings Move ECG. The pulse oximetry measurements, ECG measurements, and atrial fibrillation detection algorithm were validated in clinical studies [69]. * The Withings Body+ [70]  
The Withings Body + is a smart body scale that computes the following parameters: body weight, body fat percentage, muscle mass, bone mass, water percentage, and body mass index. It offers Bluetooth and Wi-Fi connectivity. * The Withings Body Scan [71]  
The Withings Body Scan is a smart body scale that gathers the following parameters: body weight, body fat percentage, muscle mass, bone mass, water percentage, computes body mass index, analyzes detailed segmental body composition (arms, legs, and torso), and provides a special handle that allows users to perform cardiovascular measurements, including a 6-lead ECG and nerve activity assessment, detecting signs of neuropathy, as well as analyzes electrodermal activity. It provides Bluetooth and Wi-Fi connectivity. * The Withings Sleep Analyzer [72]  
This is a special kind of device, similar to a blanket, that is positioned under the mattress. It monitors respiratory rate, heart rate, apnea episodes, respiratory events, and it analyzes sleep to identify sleep stages and quality, wake up moments, getting out of bed events, and other sleep-related data; it has a total of 36 parameters available through the provided SDK. It is clinically validated for the detection of moderate-severe sleep apnea syndrome [73]. The device offers Bluetooth and Wi-Fi connectivity. * The Withings Thermo [74]  
This is a smart-body contactless thermometer using 16 infrared sensors for high accuracy. The device offers Bluetooth and Wi-Fi connectivity. * Fitbit Charge 5 [75]  
Fitbit Charge 5 is a wearable watch with very similar capabilities to the Withings Move ECG Watch, with the key advantage of continuous heart rate and oxygen saturation monitoring, not just while performing an ECG. It provides heart rate, blood oxygen saturation, activity related data, number of steps and floors climbed, workout activities, and it assesses walked distances and burned calories. It analyzes sleep, identifying sleep stages and assessing sleep quality correlated with heart and breathing rate data. It also detects atrial fibrillations.
