RMIT researchers have created an experimental 3D-printed diamond–titanium device that generates electricity from flowing liquid and receives wireless power through tissue making it possible to remotely sense changes in flow.

Maintaining balance while walking may seem automatic—until suddenly it isn’t. Gait impairment, or difficulty with walking, is a major liability for stroke and Parkinson’s patients. Not only do gait issues slow a person down, but they are also one of the top causes of falls. And solutions are often limited to time-intensive and costly physical therapy.
