High resolution screen-printing of carbon black/carbon nanotube composite for stretchable and wearable strain sensor with controllable sensitivity

With the growing trend of accelerating sensor miniaturization, high-resolution printing technology of stretchable sensors is becoming increasingly important. In this study, we demonstrated stretchable strain sensor with various line resolutions from 50 to 500 μm based on CB/CNT composite using screen printing process for human motion detection. To optimize composite formula, we systematically investigated rheological properties of the...
