Influence of body position on bioelectrical impedance analysis

Current Directions in Biomedical Engineering
Understanding how body position changes affect bioimpedance is essential for improving wearable technology. This study assessed the influence of posture and timerelated changes on whole-body bioimpedance in 12 volunteers, who maintained sitting, standing

The Feasibility of Semi-Continuous and Multi-Frequency Thoracic Bioimpedance Measurements by a Wearable Device during Fluid Changes in Hemodialysis Patients

Sensors
Repeated single-point measurements of thoracic bioimpedance at a single (low) frequency are strongly related to fluid changes during hemodialysis. Extension to semi-continuous measurements may provide longitudinal details in the time pattern of the ...

Association Between Bioimpedance-Determined Metabolic Age and MASLD Risk Scores in Spanish Workers

Metabolites
Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent liver disorder with significant metabolic implications. Metabolic age, determined through bioimpedance analysis, has emerged as a potential indicator of overall ...
