This paper describes a low-speed wind energy harvesting system that transfers aerodynamically-induced flutter energy into electrical energy. A random airflow generates mechanical vibrations due to the fluid-structure interaction between a flexible belt and the airflow. An electromagnetic resonator with copper coils and a permanent magnet is designed to efficiently harvest electrical energy from the induced mechanical vibrations. Different groups of springs are compared at various wind conditions to maximize the power output. Typically ∼7 mW of electrical energy can be obtained at ∼3m/s wind speed with a 1 meter long belt. A power conditioning circuit with a charge pump and...

Bonding of carbon nanotubes (CNTs) onto metallic electrodes is achieved by localized induction heating. The contact bonding is formed by inductive heating the electrodes with radio frequency magnetic field. The contact resistance can be reduced by approximate 90% and the reduction is irreversible. It is demonstrated that the induction heating will selectively occurs on the structures with high electronic conductivity and relative permeability, which can be utilized to realize large scale non-contact localized heating. In addition, the atomistic study indicates that the surface charges induced by induction eddy current can improve the wetting properties between the metal atoms and CNT...
