Wearable devices derived from knee movement
If you’ve ever set of knee protectors, knee angle walk or be aware of changes. Now, a group of United Kingdom scientists try to take full advantage of all the sports, they developed a piezoelectric device that can be worn, to knee movement into electricity, future is expected to be used to drive the heart rate monitor, pedometer and accelerometer and other equipment. Knee joint energy collectors can only collect 2 MW electric power, researchers believe that improved to reach at least 30 milliwatts, enough to provide power for GPS tracking device.
