The United States made all-rubber tensile electronic devices

In a new issue of Science in the World, the research group of assistant professor of Chinese scientists at the University of Houston in the United States, Yu Cunjiang, reported that they made new breakthroughs in flexible stretchable electronics and developed stretchable rubber semiconductors and conductor materials. Use these materials to make full rubber transistors, sensors and robotic skin. In a telephone interview with Xinhua News Agency on the 9th, Yu Cunjiang said that flexible stretchable electrons have broad application prospects in fields such as health monitoring, medical implantation, man-made skin and human-computer interaction. However, the current electronic materials, especially semi-conductor materials, Therefore, people mainly achieve the purpose of stretching, such as folds, serpentines or springs, by designing special structures of these materials. However, these methods have the disadvantages of complicated technology, poor structural reliability and high manufacturing cost. Yu Cunjiang task force instead of the material itself, work hard to design and prepare based on semiconductor nanofibers and silicone rubber composite rubber semiconductor materials. These rubber semiconductors not only have excellent mechanical stretchability, but also have good electrical properties of the semiconductor can be stretched 50% of the normal work. In addition, they also developed another composite material preparation method, using gold, silver and other metal and rubber materials can be drawn to stretch rubber gold, rubber silver and other rubber conductor materials. The use of these rubber electronic materials, the group successfully made all-rubber transistor and the whole rubber temperature, pressure and other sensors. All rubber transistors can also be 50% of the work under tension in the normal work, a variety of sensors also have good sensing performance. The research group also successfully used these rubber electronic devices to make the robot skin, and realized the robot hand sensing environment and the function of translating the speech gesture. Yu Cunjiang said: "In general, all rubber electronic devices inherit the mechanical properties of rubber materials, not only has excellent tensile ductility, good electrical properties and high structural reliability, but also has a simple production process, suitable for large-scale Manufacturing, low cost advantages.It is foreseeable that all rubber electronics will promote the technological innovation of a new generation of flexible electronics.
