Abstract: Twolayer piezoelectric vibration energy harvesters using convergent and divergent tapered structures have been developed for broadband power output. The harvesters consist of a base cantilevered beam, which is attached to ...

Abstract: The tworing Ilizarov fixator is superior, in terms of space and weight savings, to the traditional fourring Ilizarov fixator. But the stiffness of the tworing Ilizarov fixator is low. This weakness causes the tworing ...
