Highly Sensitive, 3D-Printable, Piezoresistive Composite Materials for Strain Sensor Applications |
| 초록 |
Interest in personalized health-monitoring, human motion detection, human/machine interfaces, and soft robotics has expanded to wearable, stretchable, and highly sensitive strain sensor materials. Here, we have developed direct-printable, piezo-resistive strain sensor materials composed of carbon filler and elastomer. We blend carbon composite materials, triblock copolymer elastomer and organic solvents to formulate highly viscoelastic pastes. We adjust the fundamental properties and morphologies of carbon fillers and the interfacial properties between carbon filler and elastomer, in order to endow highly sensitive sensor characteristics and enable a direct-printing process. The optimized strain sensor material is demonstrated to allow for a wide sensing range from 1% to 70% in strain and show a high sensitivity with a gauge factor over 70. |
