Magnetic 3D-printed pen could help diagnose people with Parkinson’s

Study utilises handwriting-generated electrical signal to measure tremor in tandem with AI machine learning

It won't be much good for taking down notes, but a 3D-printed pen filled with magnetic ink could help identify people with Parkinson's disease, a small pilot study suggests.

More than 10 million people worldwide are thought to be living with Parkinson's, a neurodegenerative disorder with symptoms including tremors, rigidity, slowness of movement and mobility difficulties. While there is no cure, early diagnosis can help those affected access support and treatments earlier.
