Abstract
The invention is a system incorporating a self-tuning resonator and method of self-tuning a resonator within a system. In one embodiment, a method of powering a system with energy harvested from a vibrating surface includes receiving a first mechanical energy at a first driving frequency from the vibrating surface, transferring the received first mechanical energy to a suspended structure within the system, vibrating the suspended structure with the transferred first mechanical energy, passively adjusting the resonant frequency of the suspended structure to a first resonant frequency associated with the first driving frequency by moving a movable mass in response to the movement of the suspended structure, vibrating the adjusted suspended structure with the transferred first mechanical energy, generating electrical energy using the vibrations of the adjusted suspended structure, and powering the system with the generated electrical energy.

9. A wireless device, comprising:
-
a support structure configured to receive mechanical energy generated by a vibrating source external to the device; a vibratory member operatively connected to the support structure for receiving mechanical vibrations from the support structure; and a power harvesting subsystem including a resonator with at least one resonant frequency adjustment mass movably responsive to the vibratory member, such that vibration of the vibratory member causes the at least one resonant frequency adjustment mass to move thereby changing the resonant frequency of the vibratory member from a first resonant frequency to a second resonant frequency. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
