Abstract
A method for generating electrical power from an acceleration of an object is provided. The method including: vibrating a mass-spring unit upon an acceleration of an object; transmitting a force resulting from the acceleration from the mass-spring unit to the one or more piezoelectric elements; converting the vibration of the mass-spring unit to an electrical energy; and calculating at least one of the force and acceleration based on an output of the one or more piezoelectric elements.
Claims17
A device associated with an object, the device comprising:
- a mass-spring unit having a spring element and a mass disposed at one end of the spring element, the mass being free to vibrate upon an acceleration of an object;
- one or more piezoelectric elements disposed between another end of the spring element and a portion of the object such that the mass-spring unit transmits a force resulting from the acceleration to the one or more piezoelectric elements and converts the vibration of the mass-spring unit to an electrical energy;
- and
- a processor for calculating at least one of the force and acceleration based on an output of the one or more piezoelectric elements.
