Core Viewpoint - The article discusses a groundbreaking technology called "liquid droplet printing," developed by a team led by researcher Song Yanlin from 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 [2][6]. Group 1: Technology Overview - The "liquid droplet printing" technology enables the attachment of fragile electronic devices to irregular surfaces such as human skin, nerves, and even the brain, without causing damage [3][5]. - The process utilizes a droplet of water to pick up the ultra-thin membrane and release it onto the target surface, facilitating adhesion through capillary action while acting as a lubricant to prevent stress and damage [3][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 non-destructive and conformal attachment, which allowed for the conversion of light signals into electrical signals to stimulate movement [5]. Group 3: Future Applications - This technology breaks the limitations of traditional flexible electronic device attachment and has broad application potential in fields such as brain-computer interfaces, neural regulation, and wearable devices, with possibilities extending 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 [6][7].
