When the electronic screens on the streets of Pyongyang lit up with the image of a humanoid robot, this mysterious country once again threw a technological bombshell at the world. In an interview with Kim Kwang-hyuk, the director of the Artificial Intelligence Technology Research Institute at Kim Il-sung University, a delicately featured female robot smoothly … Read more
Hydrogels, as a hydrophilic three-dimensional network polymer, have shown tremendous application potential in cutting-edge fields such as tissue engineering, drug delivery, and soft robotics in recent years. However, traditional hydrogels often suffer from poor mechanical properties and limited molding methods, making it difficult to meet the demands of complex application scenarios. Frontal polymerization (FP), an … Read more
With the rapid development of technology, our lives are adorned with one marvelous invention after another. Recently, a striking technology—3D printing—has brought us new surprises. Can it print a ‘self’? The answer may be closer than you think. Imagine if you could print a model of your appearance, expressions, and body shape to take home … Read more

Banner This article is produced by「Light Science Popularization Studio」. Author: Zhang Senhao Reviewer: Wang Ling Abstract In the early morning, your fingertips touch the smartphone screen—a beam of invisible light instantly emerges from beneath the screen, like an explorer climbing over the “mountains” and “valleys” of your fingerprint, transforming the uneven patterns into a password … Read more
Laboratory Introduction The Key Laboratory of 3D Printing Technology and Equipment in Zhejiang Province was officially established in August 2014. Currently, a dedicated 3D printing laboratory of 3000 square meters has been built at Zhejiang University, Zijingang Campus. The laboratory relies on the existing advantages and hardware foundation of the national key discipline of Mechanical … Read more
Wearable devices represented by smartwatches and head-mounted displays can now utilize flexible circuit boards. However, the next generation of wearable devices requires stretchability and conformability to flexibly follow body movements and collect various data from the body. This is the purpose of developing stretchable circuit boards. Stretchable circuit boards need to possess mechanical properties that … Read more
“If you could swallow a surgeon, then surgery would become interesting and simple.” — Richard Feynman This was the fantasy of Nobel Prize-winning physicist Feynman 60 years ago. Now, the “surgeon” inside the body has become a reality — microrobots. Remote-controlled microrobots with active steering capabilities have broad prospects in medical applications. Recently, researchers from … Read more
In recent years, sensors have been developing towards sensitivity, precision, adaptability, compactness, and intelligence. In this process, fiber optic sensors, a new member of the sensor family, have gained much favor. Fiber optics possess many excellent properties, such as resistance to electromagnetic interference and atomic radiation, fine diameter, soft texture, and lightweight mechanical properties; electrical … Read more
In an article published in the journal Science, a research team from the United States developed a platform called Imaging-Guided In Vivo Acoustic Printing (DISP). This technology aims to overcome the limitations of traditional 3D printing in medical applications, particularly the need for invasive surgery. DISP achieves precise and rapid crosslinking of biomaterials in deep … Read more
