The idea is to use active cancellation (which is currently in noise cancelling headphones) to stabilize larger scale motion, he says. At the University of Michigan, I was doing my PhD on new materials that can be used for active cancellation in the military.
I figured out how to make the hardware for active cancellation of human tremor very small, and realized that this would be the perfect application for active cancellation technology.In his studies, Pathak noticed little technology has been developed to help people with essential tremor and Parkinsons disease. Pathak says, People have tried making contraptions that force a persons tremor to cease, but these looked like robotic arms that I would hate to use in public. I thought that the concept of active cancellation would be of huge help here.
One of the greatest blessings was watching my Granny eat two pieces of my birthday cake with her new spoon!
