SOUNDBITE (Chinese): PENG HUISHENG, Professor at Fudan University's Department of Macromolecular Science and Institute for Fiber Electronic Materials and Devices STORYLINE: A team of Chinese scientists has developed a soft and breathable piece of clothing that can not only store energy but also power personal electronic devices such as smartphones and watches. Replacing conventional liquid electrolytes with polymer gel electrolytes is a highly effective strategy for enhancing the flexibility of wearable batteries. However, the inadequate wetting at the interface between the polymer gel electrolyte and the electrode degrades the electrochemical performance, particularly when the battery undergoes deformation. The researchers from Fudan University have cr

Chongqing-Kunming high-speed railway advances further in construction

STORY: Chongqing-Kunming high-speed railway advances further in construction SHOOTING TIME: March 26, 2024 DATELINE: March 27, 2024 LENGTH: 00:00:50 LOCATION: KUNMING, China CATEGORY: SOCIETY SHOTLIST: 1. various of the tunnel STORYLINE: Construction of the Chongqing-Kunming high-speed railway in southwest China's Yunnan Province is progressing remarkably. As of Tuesday, the 21.17-km-long Binghui tunnel, part of the high-speed railway, has reached 20,042 meters in digging progress. The tunnel is classified as a Class I high-risk tunnel due to dangers like rockfall, collapse, and bottom deformation. Despite these obstacles, the project team has implemented effective measures to ensure safe, high-quality, and efficient construction. Xinhua News Agency correspondents reporting from Kunming, China.

Universal Gripper at Kobe Municipal College of Technology

In the experiment, we were able to estimate the contact position by dividing the gripper into six sections. The spring electrode is soft and does not interfere with the deformation of the gripper. Metal powders such as copper and iron can be used in addition to aluminum. In general, the suction gripper can judge the success of gripping by measuring the suction pressure. However, the information is limited only to success or failure, and if the gripper is sucked halfway, it is difficult to know how it is displaced. If the deformation of the gripper can be estimated, the movement can be corrected and the grasp can be resumed. The tactile judgment was processed quickly, and the blind spot became a problem when it was confirmed by photographing with a camera. = December 20, 2019, location unknown, credit: Nikkan Kogyo Shimbun / Kyodo News Images
