Special Issue Information

Dear Colleagues,

Preventive and occupational medicine requires the acquisition of physiological, psychological, physical, and prior medical data to generate a patient-specific model that can be used to detect anomalies. This Special Issue is looking for papers that deal with a decentralized multi-sensor-fusion approach based on flexible mobile data-collection platforms that can be used to create a preventive health-management system. We are looking for novel algorithms and hardware systems that can connect, acquire, and synchronize various sensors attached to a person's body and then securely transmit the fused data to a cloud server. The data used by such systems may include different mobile data sources from a remote data collection system, including directly coupled wireless sensor devices, indirectly connected devices from vendor-specific cloud solutions, and prior medical knowledge. Once received at the could server, the fused data time series is then analyzed using multivariate machine learning algorithms to detect abnormal conditions that can then be transformed into a human-understandable form that users or clinicians can quickly understand. Pertinent topics include the following: 

  • Temporal synchronization techniques of various sensors using local body networks
  • Low-level sensor fusion algorithms to compensate measurement artifacts created by patient's activities such as motion wonders in ECG measurements and temporal coincidence algorithms to reduce false alarms in fall detection
  • Multivariate temporal algorithms to detect and classify abnormal conditions
  • Novel techniques to train patient-specific models from sensor data
  • Novel algorithms to transform the classification of sensor data into human-understandable explanations
  • Novel techniques for secure transmission and processing of sensor data, such as:
    • Use of homomorphic encryption techniques to process data
    • Scalable private networks capable of dealing with a large population

Today’s wearable medical devices are becoming popular because of their price and ease of use. Most wearable medical devices allow users to continuously collect and check their health data, such as electrocardiograms (ECG). Therefore, many of these devices have been used to monitor patients with potential heart pathology as they perform their daily activities. However, one major challenge of collecting heart data using mobile ECG is baseline wander and motion artifacts created by the patient’s daily activities, resulting in false diagnoses. This paper proposes a new algorithm that automatically removes the baseline wander and suppresses most motion artifacts in mobile ECG recordings. This algorithm clearly shows a significant improvement compared to the conventional noise removal method. Two signal quality metrics are used to compare a reference ECG with its noisy version: correlation coefficients and mean squared error. For both metrics, the experimental results demonstrate that the noisy signal filtered by our algorithm is improved by a factor of ten. Full article
