太科幻了！我国科学家开发出“液滴打印”新技术

Core Insights - The article discusses advancements in flexible electronics, particularly a new method for transferring ultra-thin films to biological surfaces without stress damage, which is crucial for applications in wearable electronics and brain-machine interfaces [1][2]. Group 1: Technology Development - A novel ultra-thin film transfer strategy called droplet printing has been developed, which allows for the non-destructive transfer of electronic films to various surfaces, including biological tissues [1][2]. - The droplet printing method creates a temporary lubrication layer during the transfer process, enabling local sliding and dynamic stress release, thus preventing the rupture of delicate electronic components [1][2]. Group 2: Research Applications - The technology has been successfully tested in vivo, where ultra-thin silicon-based electronic films were printed onto the surfaces of mouse nerves and brains, achieving high-resolution infrared control of neural activity [2]. - This research provides critical technological support for the fields of flexible electronics and brain-machine interfaces, addressing the challenge of stress-induced damage during film attachment [2]. Group 3: Collaborative Efforts - The research was a collaborative effort involving multiple institutions, including the Capital Medical University, Nanyang Technological University, and Beijing Tiantan Hospital, highlighting the interdisciplinary nature of the project [2]. - Key contributors to the research include Dr. Li An, Associate Researcher Li Huizeng, and several other experts from the collaborating institutions [2].
