ABSTRACT
In this work, we present a highly stretchable dry electrode composited with carbon nanofiber (CNF) for wearable device by simple method. The fabricated electrodes were assembled with snap connector for connect with electric circuit and sticky polymer for improving adhesion strength on the skin. We evaluated the electrical and mechanical properties depending on the weight % (wt%) and thickness of CNF/elastomer composited stretchable electrode. From the results, the electrical characteristic was improved as increasing concentrations of CNF and their dropping volume. And we evaluated a stretchability and electromechanical property using with cycling test. Through these tests, we have demonstrated that fabricated dry electrode has outstanding stretchability and durability under stretching condition. Finally, electrocardiogram (ECG) was measured with these electrodes. The results of ECG measurement showed similar or larger signal that of commercial wet electrode. Consequently, these results are expected to apply as a wearable device such as a bio-signal measurement and strain sensors.
