1. An inertia driven energy harvester comprising:
- a housing;
a first arm comprising a body, said first arm coupled to said housing via a hinge connection permitting said first arm to swing responsive to a force of a surrounding environment from movement of the housing;
a first mass attached to said first arm to swing with said first arm responsive to the force of the surrounding environment;
a bumper that restricts the motion of said first arm as it swings;
a first spring coupled to said housing and to an upper surface of said first arm to suspend said first arm from said housing, wherein said first spring has a spring rate of about 0.01 Nm/Deg to about 5.0 Nm/Deg adapted for capturing low frequency vibrations of said surrounding environment from the movement of the housing;
a gearing system connected to said first arm for transferring a kinetic energy of said first arm as it swings; and
a generator connected to said gearing system for transforming said kinetic energy transferred by the gearing system to the generator into electricity.

16. An inertia driven energy harvester comprising:
-
a housing; an arm rotationally coupled to said housing to permit said arm to rotate responsive to a force of a surrounding environment from movement of the housing; a mass attached to said arm to rotate with said arm responsive to the force of the surrounding environment; a spring coupled to said housing and to an upper surface of said arm to suspend said arm from said housing; a gearing system connected to said arm for transferring a kinetic energy of said arm as it rotates; and a generator connected to said gearing system for transforming said kinetic energy transferred by the gearing system to the generator into electricity, wherein said generator is operable as a motor to provide an initial driving force to said arm to induce movement of said arm from an initial rest position. - View Dependent Claims (17, 18, 19, 20, 21, 22)
