Description
Thin Film Piezoelectric Wave Power Generation System
TECHNICAL FIELD:
[0001] The present invention relates to generating electricity from wave power.
SUMMARY OF THE INVENTION:
[0002] The present invention provides an electrical generating system, comprising: an array of submersible thin film piezoelectric strips, wherein each of the film piezoelectric strips comprises a buoyancy device for holding the strip in a vertical orientation; and an array of energy harvesting circuits, wherein electrical energy generated by flexing each of the thin film piezoelectric strips is harvested by an associated energy harvesting circuit.
[0003] Preferably, the buoyancy device is a positive buoyancy device positioned at a top end of the piezoelectric strip, and it may optionally be a gas filled chamber. In other embodiments, the buoyancy device is a negative buoyancy device positioned at a bottom end of the piezoelectric strip, and it may optionally be a weight. In either vertical embodiment, a protecting jacket encapsulating each of the submersible thin film piezoelectric strips may also be included.
[0004] In preferred embodiments, each of the thin film piezoelectric strips may be made of a 0.005 "(125 μm) polyester layer laminated to a 28μm piezo film element. In one exemplary embodiment, the thin film piezoelectric strips are made of a laminated polyester layer (0.005", or 125μm) attached to a 28μm or 52μm Piezo film element (such as Measurement Specialties, Inc LDT series). An advantage of using a laminated thin film piezoelectric strip is that, when used in a 'bending' mode, laminated film elements develop much higher voltage output when flexed than non-laminated piezoelectric strips.
[0005] Optionally, Fluoropolymer polyvinylidene fluoride (PVDF) may be used. The advantage of this embodiment is that it exhibits very high piezo-activity when polarized. While other materials like some ceramics, nylon, and PVC also exhibit the effect, none are as highly piezoelectric as the preferred piezo polymer PVDF. For example, the piezoelectric constants of: PIEZO FILM (Strip sensor) PVDF are 216 x 10"3 Vm/n.
[0006] The present invention also provides a method of generating electrical power from waves, comprising: placing an array of submersible thin film piezoelectric strips
under water, wherein each of the film piezoelectric strips comprises a buoyancy device for holding the strip in a vertical orientation, wherein back-and-forth movement of each of the thin film piezoelectric strips generates electrical energy; and harvesting the electrical energy generated from back-and-forth movement of each of the thin film piezoelectric strips.
[0007] Having a buoyancy device or chamber at the top (or bottom) ends of each of the piezoelectric strips offers the advantages of ensuring that the thin film piezoelectric strip are fully upwardly (or downwardly) extended, thus increasing the drag at the tips of the piezoelectric strips. Both of these factors would increase the electrical output caused by flexing the piezoelectric strips back-and-forth.
[0008] Preferably, the array is placed such that the thin film piezoelectric strips are under the surface of the water at a depth such that surface wave motion moves top ends of the thin film piezoelectric strips back-and-forth. This may be accomplished by placing the array of submersible thin film piezoelectric strips near a shoreline. Alternatively, the array of thin film piezoelectric strips may be suspended from the bottom of a floating or non-floating structure, such as a boat, dock, pier, buoy or even floating airport.
[0009] Also preferably, the plane of the thin film piezoelectric strips are placed in a plane perpendicular to back-and-forth motion of the water caused by surface wave motion.

DETAILED DESCRIPTION OF THE DRAWINGS:
[0016] As seen in Figs. 1 to 3, the present invention provides an electrical generating system 10, comprising: an array 12 of submersible thin film piezoelectric strips 20, wherein each film piezoelectric strip 20 comprises a buoyancy device 21 for holding strip 20 upright; and an array of energy harvesting circuits 31. As can be seen array 12 may be a two-dimensional array (with piezoelectric strips 20 lined up side-to-side and in front of one another).
[0017] In operation, electrical energy is generated by flexing each thin film piezoelectric strip 20 back-and-forth, and the electrical energy is harvested by an associated energy harvesting circuit 31. As such, each piezoelectric strip 20 preferably has its own energy harvesting circuit 31. It is to be understood, however, that the present invention is not so limited and that electrical energy from multiple piezoelectric strips 20 may be harvested by the same harvesting circuit 21.
[0018] In optional preferred embodiments, each piezoelectric strip 20 may be made of silicon or urethane jacketed piezoelectric strips or cables. It is to be understood, however, that the present invention is not so limited and that piezoelectric strip 20 may be made of other suitable materials and compositions.
[0019] In optional preferred embodiments, each energy harvesting circuit 31 may be made of Teflon jacketed, or laminated polyester piezoelectric strips or cables. It is to be understood, however, that the present invention is not so limited and that energy harvesting circuit 31 may be made of other suitable materials and compositions.
[0020] In preferred embodiments, a buoyancy device 21 is positioned at or near the top end of each piezoelectric strip 20. In preferred embodiments, buoyancy device 21 may be gas filled chamber. It may be made of a void in the end of a laminated polyester, silicon or urethane jacketed piezoelectric strip or cable, and filled with air. The advantage of this
embodiment is that buoyancy device 21 may be encapsulated within a protecting jacket that encapsulates each piezoelectric strip 20.
[0021] Specifically, in preferred embodiments, a protecting jacket 22 may encapsulate each of piezoelectric strips 20 (as seen in Fig. 2). Protecting jacket 22 may optionally be made of Teflon, polyester, urethane or silicon. It is to be understood that the present invention is not so limited and that other designs are also contemplated all keeping within the scope of the present invention.
[0022] A connector 32 may be used to attach piezoelectric strip 20 to its energy harvesting circuit 31. Electrical power harvested by energy harvesting circuit 31 may be sent through lines 33 to a central collector 34 (Fig. 3).
[0023] Having set forth one embodiment the preferred structure, operation of this embodiment of the present invention will now be explained.
[0024] The present invention provides a method of generating electrical power from waves, comprising: placing an array 12 of submersible thin film piezoelectric strips 20 under water, wherein each of film piezoelectric strip 20 comprises a buoyancy device 21 for holding strip 20 upright, wherein back-and-forth movement (in direction W) of each of thin film piezoelectric strip 20 generates electrical energy; and harvesting the electrical energy generated from back-and-forth movement of each of the thin film piezoelectric strips 20.
[0025] In one preferred aspect, the array 12 of submersible thin film piezoelectric strips 20 is placed under water such that thin film piezoelectric strips 20 are positioned under the surface of the water at a depth such that surface wave motion (in direction W) moves the top ends of the thin film piezoelectric strips back-and-forth. (This back-and- forth direction of movement in direction W can be seen in Figs. 1, 2, 4 and 5.) As can also be seen in Fig. 1, array 12 is preferably positioned near a shoreline at a depth shallow enough such that the waves move the top ends of piezoelectric strips 20 back-and-forth (in direction W). As can also be seen, array 12 is also positioned such that the plane each thin film piezoelectric strip 20 is perpendicular to back-and-forth motion of the water (in direction W) caused by surface wave motion. An advantage of positioning system 10 near a shoreline is that the power generated can be conveniently used for applications including, but not limited to, near shore ocean water desalination, electrical production, hydrogen production, algae forms and carbon sequestering.
[0026] As such, two beneficial effects are achieved. First, the top ends of piezoelectric strips 20 are flexed back-and-forth to generate electricity, and second, the plane of the piezoelectric strips 20 are positioned perpendicular to the direction of wave motion (in direction W), thus increasing the drag on piezoelectric strips 20, causing them to flex back and forth.
[0027] Figs. 4 and 5 show side elevation views of the flexing of a plurality of piezoelectric strips 20 in first and second positions (as a wave passes thereover). Note: this same flexing motion is seen in Fig. 2 in the dotted line positions of 2OA and 2OB.
[0028] Lastly, Fig. 6 shows an alternate embodiment of the invention in which the array 21 of piezoelectric strips 20 are suspended from the bottom of a structure (boat B). It is to be understood that in this embodiment, array 21 may be suspended from the bottom of any floating structure (such as a boat, buoy or even floating airport) as well as from any non-floating structure (such as a dock or pier).
[0029] In this second embodiment, piezoelectric strips 20 are suspended pointing vertically downward by negative buoyancy devices 21. In this embodiment, negative buoyancy devices 21 may simply comprise weights.
