1. An electrical generator comprising:

  • a flexible membrane having at least two fixed ends, wherein the membrane vibrates when subject to a fluid flow;

    an electrical conductor and a magnetic field generator configured to apply a magnetic field to the electrical conductor, wherein one of the electrical conductor and the 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 causes a relative movement between the electrical conductor and the applied magnetic field;

    whereby the relative movement causes a change in the strength of the magnetic field applied to the electrical conductor; and

    the change in the strength of the magnetic field applied to the electrical conductor induces a current flowing in the conductor.
