The use of rigid buoyant planar members 148 and 156 in this embodiment will enable the length of the flexing elastic planar members to be reduced along with the cost of the relatively expensive piezoelectric elements bonded above and below the elastic planar members compared to their cost for assembly 20. Assembly 20.1 may thus be more suitable for larger scale energy generation where costs of construction have to be minimised.
Put another way, the piezoelectric elements in this example should be polarised along their length LP as shown in FIG. 9 to 14, with like parts having like numbers and functions as the assembly 20.1 shown in FIGS. FIG. 15 shows part of an assembly 20.2 for generating energy from waves according to a third aspect. FIGS. 9 to 14 show an assembly 20.1 for generating electricity from waves according to a second aspect. FIG. 7 is a simplified schematic top view of the overall electrical system of the assembly of FIG. In this example, each of the buoyant planar members 148 and 156 includes a top portion 157 in this example made of two thick wooden slabs, between which the elastic planar members are clamped, with a thicker layer of light floating material underneath coupled to the lower slab.

10A shown in fragment and coupled together with two of the elastic planar members of FIG. Each of the buoyant planar members includes a top 148.7 and a bottom 313, with the top and the bottom being hexagonal in shape. The second side of the buoyant planar member is between the first side and the third side of the buoyant planar member. 3 by the gap 92 between elements 88 and 90. This effect is minimized by staggering the rows 81 and 89 of elements 86 and 93 of the first layer 71 of piezoelectric elements above the elastic planar members 74 relative to the rows 95 and 97 of elements 88 and 90 of the second layer 73 of piezoelectric elements below the elastic planar member. 19. This would be easier to do with the buoyant planar members in calm water at the dock rather than on an assembly.

3, the buoyant planar member 68 is thicker than the elastic planar members 74 in this example and is flexible enough to take up the shape of the wave and transfer this shape to the elastic planar members. The elastic planar members are generally rectangular sheets in shape in this example. Dolor muscular despues de hacer pesas . The float is cylindrical in shape in this example. The term buoyant planar member as herein described may also be referred to as a float. FIG. 10A is an enlarged top, side perspective view of a pair of the buoyant planar members of the assembly of FIG. In this manner, as the assembly rides over the waves, the slats 436, 442, 448, and 454 tilt relative to each other, causing the piezoelectric elements 86.4 and 90.4 and elastic planar members 74.4, 406, 412, and 416 between the slats to bend.

The elastic planar member so flattened causes compressive stress in the piezoelectric elements 226.5, 86.5, 228.5, 464, 466 and 468. Thus, when the assembly 20.5 is assembled and the elastic planar members 74.5 are clamped to the buoyant planar members 148.5 and 156.5, the elastic planar members are straightened again, further increasing in the compression of the piezo material to insure against the possibility of tensile rupture. 7, the tethers 54 and 56 carry electrical cables 57 and 59 connected via DC busses 53 a, 53 b and 53 c, and 55 a, 55 b and 55 c, respectively, to the diode bridge circuits 98 such that when waves moving in the direction of arrow 36 pass under the assembly 20, the piezoelectric elements 86, 88, 90 and 93 seen in FIG. 4, each elastic planar member 74 has a bottom 76 and a top 78 and is generally rectangular in top and bottom profile in this example when viewed from above.

The piezoelectric elements 86 and 88 comprise, in this example, thin top and bottom layers of material laminated to the elastic planar member 74 and which together form an elastic beam that is sufficiently flexible to conform with the waves 26 and 28. Typically each elastic planar member may be 90% or more of the total thickness comprising the sum of the thicknesses of the elastic planar member and piezoelectric elements. Each pair of electrodes and the piezoelectric material therebetween define a power generating element. In this example, the elastic planar member is pre-stressed in tension while the piezoelectric elements are being bonded thereto in order to pre-compress the piezoelectric material so that the material is less prone to cracking at the tops and in the troughs of the steeper waves.
Pre-stressing the elastic planar member 74 by bonding the piezoelectric elements thereto while the elastic planar member is under tension subjects the piezoelectric elements to compression. 3) An assembly for generating energy from waves, the assembly comprising: a buoyant planar member that is flexible; and a plurality of piezoelectric elements that are operatively coupled to an elastic planar member extending along the buoyant planar member. The ends 162 and 164 of the buoyant planar members 148 are longer than the sides 158 and 160 of the buoyant planar members in this example. 5, the assembly 20 includes a first plurality of piezoelectric elements per each of the elastic planar members 74, 75, 77 and 79, in this example a first, planar, upper layer 71 of longitudinally spaced-apart rows of piezoelectric elements relative to longitudinal axis 67. This is shown for elastic planar member 74 by a first row 81 of spaced-apart elements 83, 85 and 86, and a second row 89 of spaced-apart elements 91 and 93 that are staggered relative to the elements of the first row.
A sixth said elastic planar member couples to and extends between the second side of the sixth said buoyant planar member and the fifth side of the first said buoyant planar member. 15 for the buoyant planar member 148.2 of the third aspect. 9 to 14 with decimal extension “0.2” replacing decimal extension “0.1”, and being added for numbers not previously having decimal extensions, with the following exceptions.
4) The assembly of clause 3 with the piezoelectric/elastic planar member that extends along and operatively couples to the buoyant planar member and is operatively coupled to that layer. 11, each of the buoyant planar members 148 have a length LB of three to four meters long. Spray para el dolor muscular . The elastic planar members 74 are also thus between the first layer of piezoelectric elements and the second layer of piezoelectric elements.
According to a first aspect, there is accordingly provided an assembly for generating energy from waves. In particular, there is provided a floating piezoelectric assembly for generating energy from waves. According to a second aspect, there is provided an assembly 7for generating energy from waves. The layers of the electroactive polymers in the compressed sections are charged with the aid of control electronics, and thereafter excess electrical energy resulting from relaxation of these sections and the associated separation of the charges in the electroactive polymer is extracted by a capacitive discharge. According to a third aspect, there is provided an assembly for generating energy from waves. BRIEF SUMMARY OF INVENTION There are provided, and it is an object to provide, improved piezoelectric assemblies for generating energy from waves. The energy to produce the bending comes from the waves. Electric energy is generated thereby.
Having therefore the equations for the energy involved and knowing the wave speed and frequency, one may calculate a power level. Que es dolor muscular . However as the wave passes and the bending stresses are relieved, the energy is not completely returned to the wave as it would be with a simple elastic beam. This may produce four times as much energy as stretching the piezoelectric elements across the polarised direction which is the normal mode in which they are used. The piezoelectric elements are thus only on the tops 78.4 of the elastic planar members. If installed such that a buoyant planar member would have prevented the ability of any of the rest of the buoyant planar members 177, 280, 286, 294, 288 and 282 to move with the action of the waves. The fourth side of the buoyant planar member is between the third side and the fifth side of the buoyant planar member.

The wave-interacting portion 48 of the assembly 20 has a width WWI that extends between the sides thereof. The first layer 71 of piezoelectric elements 86, the second layer 73 of piezoelectric elements 88 and the elastic planar member 74 are therefore between the buoyant planar member 68 and the weighted planar member 80 in this embodiment. The piezoelectric elements 228 and 234 of the first upper row 263 thereof are staggered relative to at least one of the piezoelectric elements of the second upper row 265 thereof, in this example piezoelectric element 86.1. The piezoelectric elements 226 and 230 of the third row 267 thereof longitudinally align with respective ones of the piezoelectric elements 228 and 234 of the first row 263 thereof. 1, the assembly 20 includes at least one and in this example a pair of connecting members, in this case tethers 54 and 56 that releasably tether the wave-interacting portion 48 of the assembly 20 to buoy 38. As seen in FIG.
