Development of Transferable, Wearable and Flexible Electrodes

All living creatures generate physiological signals throughout their lifespan. These signals carry important information in terms of their health conditions. Therefore, these data should be detected sensitively and accurately. Conventional electrodes, which are widely used for this purpose today, have significant disadvantages such as high impedance, low contact surface with tissue, high signal noise. This causes errors and losses in the data in the first stage of collection of physiological data from the body. In this study, nanostructured wearable and transferable electrodes were designed in order to prevent the problems caused by conventional electrodes and to increase the quality and efficiency of the signals. These electrodes, which have high flexibility and a wide tissue electrode interface integrated with the tissue, allow mobile and long-term signal recording. The performance of the designed electrode was analyzed in Matlab and Biopac programs by using an oscillator that modeled physiological signals in-vitro and by recording human electromyograms in-vivo. These electrodes, which can be designed elegantly without causing visual pollution, have high conductivity and maintain low resistance stability even when stored at room conditions for a long time.
