A Highly Stretchable and Self-healing Strain Sensor for Motion Detection Strain sensors are devices that can convert force, pressure, tension, and weight into a change in electrical resistance (i.e., capacitance), which can then be measured. Such sensors can be used to create a variety of devices that can detect motion in their surroundings, including robots, health monitoring devices, and smart human–machine interfaces. Researchers at Fudan University, Tongji University, and the Chinese Academy of Sciences have recently developed
a new strain sensor that is highly stretchable, efficient, and sensitive to motion-related changes in its environment and can monitor a variety of human motions in real time. When combined with silicon integrated circuits, it can then transfer the data it recorded directly to a smartphone or another smart device via Bluetooth. The sensor can thus be used to monitor and keep track of human body motions, which is particularly useful for the development of health and fitness tracking devices. This sensor also has selfhealing capabilities, as it is made of an ionic and conductive poly(acrylamide) hydrogel, and can quickly and effectively repair itself when torn or damaged.

The new strain sensor can also be used to create technology that recognizes human gestures. The smart glove created by the researchers can express and recognize American sign language. This means that it could be used to enable more engaging interactions between deaf individuals who use ASL and machines. Moreover, the smart glove can be used to wirelessly control a robotic hand, by performing the desired hand gestures while wearing the glove. The sensing device developed by the researchers has already shown great potential for a wide range of applications, including human–machine interfaces, interactive robots, health monitoring systems, and fitness trackers. In the future, it could be used to fabricate a number of new smart devices with advanced motion sensing capabilities.

Experimental Physicists Study Steel on Board the International Space Station For many years, the Institute of Experimental Physics at Graz University of Technology and the Styrian industrial company Bo¨hler Edelstahl have been conducting joint research on the surface tension and temperature dependence of different types of steel. Steel in particular is the focus of interest here, because it will be needed in metallic laser 3D printing to produce steel components using this new remelting technology in the future. Conventional examination methods only work up to a certain upper temperature limit. At higher temperatures, problems can occur with the sample container, such as interactions between the container and the sample, and this would falsify the measuring results. For the
