Development of Flexible Carbon-based Hydrophobic Electrodes for Skin Conductance Measurements
Abstract
Project Summary/Abstract Our prior work has demonstrated successful development of hydrophobic ECG electrodes. The current proposal is to examine if these hydrophobic ECG electrodes can be used for measuring skin conductance response (SCR). The proposed study will enable collection of continuous SCR data during SCUBA, a feat that has not been possible to date. The first objective of the study is to determine the optimal electrode size for the best signal quality data acquisition. The second objective is to develop an adhesive approach for fastening to skin since our current design requires an adhesive tape to secure onto skin. The reason for needing adhesive is to seal the SCR electrodes so that water do not penetrate the electrodes; this will require the electrodes to be flexible since the electrodes will need to be placed on either fingers or underside of the wrist. The third objective of the study is to demonstrate feasibility of the SCR electrodes for measuring electrodermal response in dry condition during induced stressors. In addition, we aim to compare SCR signal to the sympathetic tone obtained via the principal dynamic mode analysis to determine if there is correlation between the two methods. The fourth objective of the study is to test carbon based SCR electrodes for WI testing. Our hydrophobic electrodes will enable SCR data collection from which computational analyses will facilitate a more extensive examination of autonomic dysfunction as one of the primary putative mechanisms of reduced performance and fatigue. An accurate understanding of the problem will ultimately lead to guidance and interventions to improve performance following long-duration missions, and enhance overall diver safety and mission completion.
