AMPG device for generation of electrical energy from vibrations, an AMPG device assembly, and a method to optimize the generation of said electrical energy

A printed circuit board, comprising:

• at least one accumulating motion pulse generator device comprising a bobbin, at least one first magnet, and at least one first spring member, wherein said first magnet is arranged to be movable together with said first spring member, said device is arranged so that when exposed to an acceleration component in a possible path of mobility of said first magnet, said first magnet will due to its association with said first spring member arranged to move in an oscillating manner in relation to said bobbin, so as to generate electrical energy, and a second spring member at a limiting position of said mobile magnet's path of mobility for limiting said path of mobility.

An accumulating motion pulse generator device assembly comprising

• at least two of the accumulating motion pulse generator devices each comprising a bobbin, at least one first magnet, and at least one first spring member, wherein said first magnet is arranged to be movable together with said first spring member, said device is arranged so that when exposed to an acceleration component in a possible path of mobility of said first magnet, said first magnet will due to its association with said first spring member arranged to move in an oscillating manner in relation to said bobbin, so as to generate electrical energy, and a second spring member at a limiting position of said mobile magnet's path of mobility, for limiting said path of mobility, wherein the accumulating motion pulse generator devices are mounted angularly displaced relative to each other, whereby the AMPG assembly is able to collect acceleration components in more than one direction.

A method to optimize the electrical output from an accumulating motion pulse generator device, the method comprising:

• determining a frequency range of the vibrations emerging from an application in which the accumulating motion pulse generator device is intended to be used,
• adapting at least one resonant frequency of the accumulating motion pulse generator to the determined frequency range, and
• using the accumulating motion pulse generator device in an application with vibrations in a frequency interval comprising said measured frequency of said application.
