Integrated current sensor and energy harvester based on microresonator energy transducer

A method of non-invasively monitoring a flow of current flow through a conductor and/or harvesting energy due to current flow through the conductor, the method comprising:

• providing a resonator comprising an oscillatable suspension assembly including a suspension and a magnetodynamic volume, the suspension having a platform on which the magnetodynamic volume is connected, the suspension assembly and components thereof being configured to oscillate under an influence of a time-varying magnetic field generated by the flow of current through the conductor which is arranged in proximity to the suspension assembly or component(s) thereof;
• and
• inducing an electromagnetic force on or through a first energy transducer, which is positioned around and in proximity to at least a portion of the magnetodynamic volume, to produce electrical energy comprising an output voltage or current that is proportional to the current flowing through the conductor,
• wherein the resonator and the first energy transducer are integrated onto or into a printed circuit board substrate or other non-conductive substrate as part of an integrated multifunctional energy system.
