Inspiration from Daily Goods: A Low-Cost, Facilely Fabricated, and Environment-Friendly Strain Sensor Based on Common Carbon Ink and Elastic Core-Spun Yarn

Cost and fabrication technique, as two important factors affecting the development and practical applications of electronic devices, have attracted extensive attention of researchers. In order to overcome the shortcomings of high-cost raw materials and complex fabrication process, in the present work, a low-cost (the cost of per strain sensor is less than one cent ($0.01)) and environment-friendly strain sensor based on common daily goods of...
