The Commonwealth Scientific and Industrial Research Organisation (CSIRO) have invented a new layer of security for wearables, by tracking the way the owner walks and recognizing slight alterations in the style.
The team also figured out a way to harvest energy from hand movement and feed it back to the wearable, potentially extending the battery life when on the move.
