The invention discloses an electromagnetic T-
shaped beam vibration
energy harvester on the basis of a rigid and flexible combined structure. The electromagnetic T-
shaped beam vibration
energy harvester comprises a rigid support plate (5), a
magnet (4) and a rigid and flexible combined plate (2). The rigid support plate (5), the
magnet (4) and the rigid and flexible combined plate (2) are sequentially arranged from bottom to top; the
magnet (4) closely clings to the rigid support plate (5), and a plurality of
copper cylinders (3) are uniformly arranged between the rigid support plate (5) and the rigid and flexible combined plate (2), so that gaps can be reserved between the magnet (4) and the rigid and flexible combined plate (2). The electromagnetic T-
shaped beam vibration energy harvesterhas the advantages that the electromagnetic T-shaped
beam vibration energy harvester is of a movable
coil structure; a coil is positioned on a rigid plate portion of the rigid and flexible combined plate, a vibration
pickup beam is in a
polyimide T-shaped beam design, the
effective length of the vibration
pickup beam can be prolonged by the design, and the
resonance frequencies of the electromagnetic T-shaped
beam vibration energy harvester further can be lowered; printed circuit rigid and flexible combination technologies are introduced into the electromagnetic T-shaped
beam vibration energyharvester for the first time as compared with other vibration energy harvesters, the electromagnetic T-shaped beam vibration energy harvester has low frequencies as compared with rigid beam harvesters, the requirements on
energy harvesting at different mounting angles can be met by the T-shaped beam design, and accordingly the electromagnetic T-shaped beam vibration energy harvester is high in harvesting efficiency.
