1. An electrical generator comprising:

  • a supporting structure;

    a flexible membrane having at least two ends supported by the supporting structure, wherein the membrane vibrates when subject to a fluid flow;

    at least one electrical conductor and at least one magnetic field generator configured to apply a magnetic field to the at least one electrical conductor, wherein the at least one magnetic field generator is attached to the membrane and configured to move with the membrane;

    wherein the vibration of the membrane caused by the fluid flow creates a relative movement between the at least one conductor and the magnetic field generated by the at least one magnetic field generator; and

    whereby the relative movement creates a change in the strength of the magnetic field applied to the at least one electrical conductor; and

    the change in the strength of the magnetic field induces a current.
