Electricity generator with undulating membrane
First Claim
1. An electricity generator comprising:
- a membrane and a support for the membrane, the membrane being adapted to undulate in a longitudinal direction of the membrane when said membrane is immersed in a fluid flowing in a given direction and is supported by the membrane support;
a first electricity generation module carried by the membrane, the first electricity generation module comprising;
a fixed frame;
a movable frame able to move with respect to the fixed frame;
a coil carried by one of the fixed frame and the movable frame;
at least one permanent magnet carried by the other of the fixed frame and the movable frame;
said coil and said at least one permanent magnet being arranged and disposed so that, when the movable frame moves with respect to the fixed frame, an electrical voltage is induced in the coil;
the generator further being characterised in that the fixed frame of said first electricity generation module is connected to the membrane, and the movable frame of said first module is offset from a neutral axis of the membrane so that, when the membrane undulates in the longitudinal direction, there is, for said first electricity generation module, a movement of the movable frame of said first electricity generation module by rectilinear sliding with respect to the fixed frame of said first electricity generation module so as to induce the electrical voltage in the coil of said first electricity generation module.

Abstract
An electricity generator that derives energy from a membrane undulating in a longitudinal direction. The generator having electricity generation modules carried on the membrane, each module having a fixed frame, a movable frame, a coil, and at least one permanent magnet carried by one of the frames in order to generate a voltage when the membrane undulates. The fixed frames are connected to the membrane and the movable frames are disposed at a distance from a neutral axis of the membrane so that, when the membrane undulates in the longitudinal direction, the moveable frame of each electricity generation module slides in a rectilinear movement with respect to the fixed frame so as to generate electrical voltages in the coils of each module.

10. An electricity generator comprising:
-
a membrane and a support for the membrane, the membrane being adapted to undulate in a longitudinal direction of the membrane when said membrane is immersed in a fluid flowing in a given direction and is supported by the membrane support; a first electricity generation module carried by the membrane, the first electricity generation module comprising; a fixed frame; a movable frame able to move with respect to the fixed frame; a coil carried by the fixed frame; at least one permanent magnet also carried by the fixed frame; wherein the fixed frame of said first electricity generation module is connected to the membrane, and the movable frame of said first module is offset from a neutral axis of the membrane so that, when the membrane undulates in the longitudinal direction, there is, for said first electricity generation module, a movement of the movable frame of said first electricity generation module by rectilinear sliding with respect to the fixed frame of said first electricity generation module, wherein said movable frame of the first electricity generation module further comprises a bar facing said at least one magnet of the first electricity generation module, the bar moving by the rectilinear sliding of the moveable frame when the membrane undulates in the longitudinal direction, the fixed frame of the first module carrying a counter-bar, wherein an inter-bar distance measured between the bar and the counter-bar varies when the membrane undulates in the longitudinal direction, and wherein the variation in the inter-bar distance caused by the rectilinear sliding of the bar creates a variation in magnetic flux from the permanent magnet passing through the coil, to thereby induce an electrical voltage in the coil.
