Claims

1. Device for generating energy, which device

comprises :

- an inverted pendulum comprising an arm oscillating about a pivot point and a mass arranged on the arm;

- spring means for preserving the equilibrium of the inverted pendulum;

characterized in that the spring means comprise at least one piezo generator for generating energy from the oscillating movement.

2. Device as claimed in claim 1, wherein the at least one piezo generator is a spring means for preserving the equilibrium of the inverted pendulum.

3. Device as claimed in claim 1 or 2, wherein mgl.sin a

< K. a

wherein :

- m is the mass arranged on the arm

- g is the gravitational acceleration

- 1 is the distance from the mass to the pivot point

- K is the spring constant of the spring means

including the spring constant of the at least one piezo generator

- a is the angle of the arm to the direction of the force of gravity.

4. Device as claimed in claim 1, 2 or 3, comprising at least two piezo generators arranged diametrically opposite each other relative to the pivot point.

5. Device as claimed in claim 4, comprising a base and a support plate arranged parallel to the base, wherein the at least two piezo generators are arranged between the base and the support plate and wherein the arm is arranged perpendicularly of the support plate.

6. Device as claimed in any of the foregoing claims, further comprising a battery and an electrical circuit for charging the battery with the energy generated by the at least one piezo generator.

7. Device as claimed in any of the foregoing claims, further comprising a wind-break arranged on the free end of the arm.

8. Method for use of a device as claimed in any of the foregoing claims, comprising the steps of:

- providing a device as claimed in any of the foregoing claims ;

- deforming the at least one piezo generator of the device with a small force, such as for instance a gust of wind, a vibration of a vehicle, an external magnetic force, rain, waves or ambient vibrations, and under the influence of the force of gravity; and

- extracting from the piezo generator the energy obtained by the deformation.
