What is it about?
The manuscript is about a method that treats an energy harvester as a vibration absorber mounted on a vibration source. It discusses how many such harvesters can be placed on a given source without drawing much energy from the source.

Why is it important?
When an energy harvester is mounted on a vibration source, the added mass would modify the dynamics of the source itself. By selecting the correct mass, stiffness, and damping for the harvester, we can make sure that much of the energy supplied by the source is transferred effectively to the harvesters.
Perspectives
The manuscript lays emphasis on identifying the dynamic characteristics of a harvester for a given vibration source. The relations for optimal transfer energy from an undamped vibration source are readily available. However, if the source is a damped vibration source, which is usually the case, the relations for optimal energy transfer are not straight forward. In this manuscript we propose an algorithm by satisfying the conditions for optimal energy transfer. This serves as a quick tool when one needs to design a harvester for a given vibration source.
