WEARABLE WELLNESS SYSTEM
The Wearable Wellness System includes
The sensorized garment
A washable garment that feels like traditional clothing, with sensors fully integrated into the fabric to sense respiratory movements and record ECG signals, providing a natural, comfortable experience.
The Data Logger
At the heart of the system, the DL enables optimized signal acquisition from fabric sensors, real-time data processing and parameter extraction, with onboard recording and Bluetooth and Wi-Fi transmission.
The software pack
A powerful toolkit for advanced data management and seamless device configuration, available in Android and Windows environments. Designed to visualize, stream, and convert device data.
The system is capable of simultaneously acquiring multiple physiological and movement-related signals in an integrated and non-invasive way:
-
1 electrocardiographic signal (ECG), with a lead configuration parallel to Lead I
-
1 respiratory signal, measured at thoracic level (lower sternum)
-
Body movements and kinematics through an integrated inertial sensing unit
The electronic device incorporates a high-performance processor . This enables the extraction of a wide range of physiological and biomechanical parameters, including:
-
Heart rate (HR) and respiratory rate
-
Heart rate variability (HRV – time domain analysis, reflecting autonomic balance)
-
RR intervals
-
Quality indices for both ECG and respiratory signals (useful for data validation)
-
Respiratory patterns over time (based on thoracic movement)
-
Posture and activity classification (e.g., lying, sitting, standing, walking, running)
-
Activity intensity estimation
-
Step rate (steps per minute)
-
Estimation of energy expenditure
In addition, the system integrates a 6 degrees-of-freedom (6DoF) Inertial Measurement Unit (IMU), combining a tri-axial accelerometer and gyroscope. Unlike systems where IMU data are used only internally, in this case raw and processed IMU data can also be accessed, allowing further analysis of:
-
Trunk acceleration
-
Angular velocity
-
Body orientation (e.g., flexion–extension, lateral bending)
-
Movement dynamics during activities

How the system works?
The ECG and respiratory signals are acquired through textile-based sensors, consisting of conductive yarns fully integrated into the garment structure.
This design eliminates the need for rigid electrodes embedded in the fabric and allows for:
-
High wearability and comfort
-
Stable signal acquisition during dynamic conditions
-
Reusability and washability of the garment
Respiratory activity is derived from thoracic expansion and contraction, enabling accurate estimation of breathing frequency and patterns, although inspiration and expiration phases are not separately distinguished.
Posture and movement are monitored via the embedded IMU and processed through advanced classification algorithms, enabling reliable detection of activity type and intensity in real-world conditions.
The system is designed with a modular approach:
-
A single acquisition module can be used across multiple garments (different sizes and users)
-
Garments are interchangeable, washable, and suitable for repeated use
-
Data are transmitted via Bluetooth Low Energy (optionally via Wi-Fi) and managed through dedicated software
The software includes:
-
Real-time data visualization
-
Signal quality monitoring
-
Data export in standard formats (e.g., CSV), allowing further analysis in tools such as MATLAB, Python, or statistical software
Thanks to its high level of comfort, wearability, and robustness, the WWS system is particularly suitable for:
-
Long-term physiological monitoring
-
Research studies with multiple participants
-
Data acquisition in dynamic conditions (e.g., walking or daily activities)
