piezoelectric energy harvester device

Hereinafter, reference to accompanying drawing configured according to an embodiment of the present invention. as further described the and application. A claimed hereinafter patent description of various aspects of the present invention (aspects) is one, the present invention of the following techniques (description) the detailed techniques. attached on the lower piece is (detailed description).

Just, describes in the present invention, publicly known functional or configuration to got any specific description is for subject matter of invention speaks out a to omitted.

Also according to one embodiment of the present invention Figure 1 shows a a piezoelectric power generation device (100) .the shown is roughly.

The implementation shown in is, according to one embodiment a piezoelectric power generation device (100) constituting a (110) lower (120) which are arranged in spaced apart relation to the, balanced close to. is preferably arranged at the. Said top plate (110) lower (120) is secured between the a piezoelectric device (130) may comprise an.

Top plate (110) lower (120) a connection portion used to connect the material (140) may be connected to by. The connections a, for example, is of the type in which is able to move rod suspension types of structures may, itself the spring structure that can be elastically deformed can be constructed or the like.

Said piezoelectric element (130) of an upper plate (110) or lower (120) opposing sides at least either a can be anchored to the face of.

For example, piezoelectric element (130) of a flexible a polymer-material can be material covers at least a part of or ceramic, said ceramic material of piezoelectric elements (130) or polymer PVDF piezoelectric element (130) device is fixed in close top plate (110) and lower (120) fixed to the seating passengers onto a passenger aircraft over the basic when vibration of a train during traveling, passenger waste gases resulting from the seating or motion set up pressure and vibration response to a simultaneously energy source to the can cause many power output per unit.

Figure 2 shows a of seat also, armrest, back, neck support , and chair a piezoelectric power generation device (100) is formed on an end is roughly is a perspective view shown the.

Piezoelectric power generation device (100) is arranged on a seat provided in a nickel aluminide covered material can be attached to (C). Also the implementation shown in 2, seat (C) of, armrest, back, neck support , or seat leg or the like selectively of the or each portion that can be affixed together by inserting a.. Furthermore, durability and passenger the ride quality of used, such as by considering the edge segment on a seat except for of (C), armrest, back, neck support , or seat leg connected with constitution: a provided at the central portion of.

Therefore, a service train vibrated influenceable by an external force for generating electric energy the decoration plate further comprises an user the seat seat force is when it has on the (C), armrest, back, neck support , or seat leg such as vibration is generated and is transmitted to the solenoid housing and, easy train waste gases resulting from vibration of the seat passenger as well as when occupant (C) for generating power by conventional pipe joint wherein a defect occurs is because of pressure can be.

Also Figure 3 shows a top plate (110) or lower (120) is bent in a collision while piezoelectric element (130) an initial distance applied strain in the outlines is a perspective view shown. Said top plate (110) or lower (120) is configured resiliently the material, said top plate (110) or lower (120) in a state that a bending load when acted upon by a, said top plate (110) or lower (120) is bent in a collision in said piezoelectric element (130) it possible to alter the.

Material resiliently configured top plate (110) is installed at the seating passenger over, the weighted by said top plate (110) is the screen is seen is bent, lower (120) faces, to a frame of the reaction are subject to forces such said lower since is bent (120) in addition, said top plate (110) and said lower (120) attached to a piezoelectric element (130) it possible to alter the. The seating passenger in addition a continuous and be continues, and inertia by train is swinging continue even, said piezoelectric element (130) is can generate power with.

Also Figure 4 shows a top plate (110) lower (120) a connecting member for connecting layers spaced-apart (140) through modification of the of the piezoelectric element (130) an initial distance is delivered kinetic energy to outlines is a perspective view shown.

() In Figure 4 has a threaded member when the suspension is. indicates the. Specifically, said connecting member (140) in the form of the vehicle suspension can take the piston shape. Types of structures may vehicle suspension formed in a restoring force according to movement of said upper plate (110) or lower (120) can move is, when the movement carried out can be back deformed. Said connecting member (140) when it has are moved into mating engagement with the railway or motion passenger movement is capable of moving up and down by the irradiation of electromagnetic waves of can be, as a result movement energy and the strain energy for said piezoelectric element (130) capable of transferring a..

Or, said connecting member (140) with elastic energy is, which may be configured to have, at this time, said top plate (110) or lower (120) while deforming it or setting it vibrating is piezoelectric element (130) with energy it possible to alter the, continue to piezoelectric element (130) oscillating or vibrating rocking a further energy can be applied.

The, said connecting member (140) the shape of the top plate (110) or lower (120) that is capable of generating movement of and what if structure. by percussion or rotary-percussion drilling.

According to Figure 5 shows a is predicted from another embodiment a piezoelectric power generation device (200) and perspective view of, said piezoelectric power generation device (200) each other spaced plurality of plates (210, 220, 230) can be constructed including.

The present embodiment is attached to a seat according to generating electrical energy a piezoelectric power generation device (200) in, spaced arranged to be of at least two plates (210, 220, 230), and said two or more the plates of (210, 220, 230) is secured between the a piezoelectric device (240, 250) includes, most generate an disposed on top of said plate (210) of the seat and is positioned on a region of a load is applied, said each plates (210, 220, 230) caused by the relative motion between the piezoelectric element (240, 250) strain in the can be applied. Furthermore, said plurality of plates coupled a connecting member for connecting (260) may include further.

At least said at least two plates, the greater piezo-electric element positioned further length of an outer circumference of the further power output per unit of the insertion part and the holder. can be increased. Said increasing the shelf plates are physically limit is implemented, spaces portion that can be attached to the selected of the disk that are used may be is. In one embodiment, seat of or a backrest the plate space provided between the layers spaced-apart plate cell the second scattered reflection but formed in a predetermined portion of the or more, spaced-apart plate the neck support or arm rest of seat can be arranged a have enough space thereof is formed the plate or cell may hereinafter, proper situation selected of the vibratable plate is may be.

Said plurality of plates (210, 220, 230) the resiliently is configured material, said most disposed on top of plate (210) in a state that a bending load when acted upon by a, said plurality of plates (210, 220, 230) is bent in a collision in said piezoelectric element (240, 250) of deforming thus.

Said connecting member (260) the resiliently is configured material, most disposed on top of plate (210) in a state that a bending load when acted upon by a, said connecting member (260) is compressed while said piezoelectric element (240) it possible to alter the.

In the embodiment according to prior described, seat inner portion piezoelectric power generation device by, external energy into electric energy in a by with a mobile, a wiring with reduced use external energy did not solve the problem..

While, the present invention refers to is limited aspect which is not the embodiment, various concept and of the present invention without a wireless type through a wire can be modified and deforming this technique in fields such. nontrivial twiddle factors and to person with skill in the art. Thus such modified examples include or modified e.g. belonging to it what the of the present invention claim is.
