Electroantennography Measurement by Printed Electronics Electrode
The possibility of measuring physiological responses using printed electronics that the authors can design easily is shown, and electroantennogram (EAG) response is measured very similar to previous research.
Abstract
In this study, we aim to measure the electrical potentials of an adult male silkworm moth using printed electronics technology. If we can measure the electrical signals of nerve cells that generate brain activity such as movement and decision making of animals including humans, it will greatly help to elucidate the adaptive mechanism of animals and reconstruct them with artificial systems. Hence, measurement data of physiological responses in moving animals have a high value. However, the physiological response measurement method has many technical difficulties, obtaining a high-quality physiological response greatly depends on the skill level of the experimenter. For that reason, we focused on printed electronics that can easily produce circuit patterns on flexible films. It is assumed that it has the possibility to be used to simplify physiological response measurements. In this study, we measured the physiological responses of the silkworm moth using printed electronics. To make an electrode suitable for measurement, we investigated the resistance value of printed electronics and prepare two electrodes based on that value. As a result, when measuring electroantennogram (EAG) of the silkworm moth using the electrode with a low resistance value, we succeeded in measuring EAG response very similar to previous research. Therefore, we showed the possibility of measuring physiological responses using printed electronics that we can design easily.
