| Research Abstract |
We have developed novel stretchable dynamic strain sensors which are composed of a multi-wall carbon nanotube (CNT) ribbon and elastic polymer. The modulus of elasticity of the fabricated CNT strain sensor is 20 times larger in stain and 5-10 times larger in the ratio of resistance variation to stain than those of conventional metal strain sensors. We confirmed that the repeated durability of the fabricated CNT strain sensor is larger than 180,000 times. It suggests that the fabricated CNT sensors are capable of practical use. In addition to them, we have developed wearable CNT strain sensors by incorporating the CNT sensors with compression stuff fit to a human body. We arranged the CNT sensors at several joints of human body and measured the signals following the movement of the human body.
