静電容量型ソフト歪みセンサの感度向上

抄録

Machines made of compliant materials, such as soft robots and wearable devices often require to detect large strains for estimating and controlling their states and deformations. Highly stretchable strain sensors, especially those rely on reading the capacitive change as a function of strain, are a promising solution for the sensing of soft machines. In this contribution, a method to increase the sensitivity of capacitive strain sensors is described, which is to use auxetic structures. Sensor prototypes made of elastomeric materials are fabricated and tested. The result shows that the sensitivity can be improved by our method.
