Innovations focus on overcoming challenges

Song Yanlin, a chemistry expert from the Chinese Academy of Sciences, delivers a lecture on Braille printing technology in May 2022. "Visually impaired children have to be really cautious when touching the dots of a traditional Braille book," says Song Yanlin, a professor at the Institute of Chemistry, Chinese Academy of Sciences. "By precisely controlling the formation of ink droplets and manipulating each droplet to create a slightly raised structure, a basic Braille character can be represented," Song says. "It marked a historic moment in the Olympics as it represents the first widespread use of inclusive materials catering to both sighted and visually impaired audiences," Song says. He is actively exploring potential collaborations with international disability support organizations and Braille printing houses to share the technology and enhance the lives of visually impaired people globally.
