Skin-to-skin contacts (interpersonal touches), such as handshakes and highfives, can be used as indices displaying the soundness of children’s body and mind development. Thus far, we have been developing bracelet devices that measure interpersonal touches using an inter-body area network via electric current between rigid metal electrodes on wrists. This paper presents wristbands fabricated with soft conductive fabrics to improve wearability as well as the quality of the network. The conductive fabrics allow us to design more flexible layouts for electrodes than rigid metal. We design several layouts and conduct experiments to study the relations between the spatial layout and signal-to-noise (S/N) ratio. The results show that the S/N ratio is improved as the area of the electrodes and the distance between the electrodes increase. Besides, one of our designed electrodes shows greater performance than the existing metal electrodes at most by 4.0 dB.
