Core Viewpoint - The article discusses a groundbreaking technology called "liquid droplet printing," developed by a team led by researcher Song Yanlin at the Chinese Academy of Sciences, which allows for the precise attachment of ultra-thin electronic membranes to complex biological surfaces using a droplet of water as a medium [1][2]. Group 1: Technology Overview - The "liquid droplet printing" technology enables the attachment of flexible electronic devices to irregular surfaces such as human skin, nerves, and the brain without damaging the delicate membranes [2][3]. - The process utilizes a droplet of water to pick up the ultra-thin membrane and release it onto the target surface, acting as both a facilitator for adhesion and a lubricant to prevent stress-related damage during application [2][5]. Group 2: Experimental Results - Experiments demonstrated that even a gold film with a thickness of only 150 nanometers could be successfully attached to complex structures like paramecium, dandelion fluff, and shell textures using this technology [5]. - In live experiments, silicon-based electronic membranes were printed onto the sciatic nerve and cerebral cortex of mice, achieving a non-destructive and conformal attachment that allowed for the conversion of light signals into electrical signals, successfully stimulating nerve activity [5]. Group 3: Future Prospects - This technology breaks the limitations of traditional flexible electronic device attachment and has broad application potential in fields such as brain-machine interfaces, neural regulation, and wearable devices, with possible extensions to tissue engineering and smart displays [6]. - The innovation is likened to the impact of printing technology on human civilization, suggesting that "liquid droplet printing" could revolutionize the preparation and attachment of electronic devices, making it as easy as applying a screen protector [6].
