If body fluid within the patient cannot be controlled, it will affect the patient''s quality of life and survival. There are several methods and instruments developed to measure the physical body compositions, however, those methods are inconvenient to operate clinically, expensive in operation cost causing biosafety risk concerns due to application of high energy radiation materials and most importantly cannot fulfill the requirement of repeated detections in routine clinical examinations. The bioimpedance measurement has the advantage of simplicity and economical operation cost, low biosafety risk and capability for repeating detection, and is widely applied as clinical tool for body water examination.Electrode patches with conductive hydrogel are the primary option of clinical bio-impedance measurements. With advances in wearable technology, textile electrodes are increasingly investigated in of electrocardiogram and pressure sensing. Therefore, the aim of the research was to evaluate the feasibility of applying textile electrode in bioimpedance detection for clinical body water monitoring. There were 20 healthy volunteers involved in the study for comparing the detected results as resistance or water content based on segmental detections between textile electrodes and conventional electrode patches. The collected data with both electrodes connected to different clinical bioimpedance detectors were analyzed to evaluate that if textile electrode can be applied to replace electrode patches as bioimpedance probe for continuous body water monitoring. The preliminary result indicated that clinical agreement achieved between detections from conventional electrode patches and textile electrode with sufficient contact area, clinical acceptable accuracy and reproducibility of textile based detection, verify the potential of textile electrode as the probe for development of continuous body water monitoring system with bioimpedance detection.
