Lucy Jung never thought much about designing for sick people. Then she was diagnosed with a brain tumor. She recovered, and the experience has driven her toward what she now thinks of her calling: to use design to help improve the quality of life of hospital patients and those with chronic conditions.

It drove the 27-year-old designer to create the Arc, a pen for people with Parkinson’s disease. Along with three fellow students (Hwan Soo Jeon, Tian-jia Hsieh, and Danny Waklin) from the UK’s Royal College of Art and the Imperial College London who took part in the Innovation Design and Engineering joint masters course, Jung designed the pen to not only make it easier for people with Parkinson’s to write legibly, but to actually loosen up the muscles of their hands after they’ve put the pen down.
