Smart Material Harvests Energy from the Knee

Smart Material Harvests Energy from the Knee
Jul-18-19
An innovative knee-worn wearable gathers energy from the wearer’s motion without hampering their stride.

The prototype device was created by a team from the Chinese University of Hong Kong to take advantage of the knee joint’s relatively long range of motion. The system features a slider-crank mechanism made from a smart macrofiber material that will generate energy when bent in any direction, and the entire wearable weighs only 0.7 pounds. In tests, the device was able to produce enough power at walking speeds to power small electronics like GPS units or medical wearables, and could be used by long-range hikers to keep their devices charged during long trips.
