伸縮性ひずみセンサの開発と応用展開

抄録

Conventionally, in order to measure the strain of the rigid, such as metal, the strain gauges are widely used. The strain measurement of the flexible object, and a wide dynamic range (for example 100% or more) strain sensor are required. Flexible strain sensor is expected to realize a variety of technologies. For example, measurement applications, human interface, smart wear, skin-motion monitoring, and robotic skin.

We have developed a stretchable strain sensor C-STRETCH^®, used the compounding techniques of elastomer and elastic conductive materials. This sensor is wide dynamic range (up to 200% elongation), very soft, very thin film, high responsiveness, and excellent measurement accuracy.
