Wind Energy Harvest Using Flexible Piezoelectric Device

Wind-generated Electrical Energy Using Flexible Piezoelectric Materials

Electrical energy can be harvested from the wind using flag-like membranes (termed piezoelements or bimorphs) composed of flexible piezoelectric materials. The flapping of the membrane caused by the wind induces bending stresses which generate a voltage across electrodes positioned on the surfaces of the material via the piezoelectric properties of the material. The best results to date using P...

Ultra-flexible Piezoelectric Devices Integrated with Heart to Harvest the Biomechanical Energy

Power supply for medical implantable devices (i.e. pacemaker) always challenges not only the surgery but also the battery technology. Here, we report a strategy for energy harvesting from the heart motion by using ultra-flexible piezoelectric device based on lead zirconate titanate (PZT) ceramics that has most excellent piezoelectricity in commercial materials, without any burden or damage to h...

Flexible energy harvesting from hard piezoelectric beams

This paper presents design, multiphysics finite element modeling and experimental validation of a new miniaturized PZT generator that integrates a bulk piezoelectric ceramic onto a flexible platform for energy harvesting from the human body pressing force. In spite of its flexibility, the mechanical structure of the proposed device is simple to fabricate and efficient for the energy conversion....
