“…The main drawback of these current sensors is the durability and reliability of the sensors. That is why the characterization and performance of the sensors highly depend on the magnetic properties of the permanent magnet (Shang et al, 2017) and the piezoelectric properties of the microbeam that degenerate over time (Jackson, Olszewski, O'Murchu, & Mathewson, 2017;Olszewski, Houlihan, Blake, Mathewson, & Jackson, 2017;Zamani Kouhpanji, 2018a). Furthermore, this type of current sensors is mainly usable for paired-wires configurations, where there is a uniform magnetic field gradient.…”

Here two different non-invasive current sensors are proposed, modeled and analyzed. The current sensors are based on the Ampere Force Law (AFL), defining the magnetic force between two parallel wire carrying currents. These current sensors can be used for detecting/sensing DC and AC currents as well as their combination in a single wire or multiple wires, and they do not rely on any permanent magnets for operation. In the first configuration, there are two microbeams, in which one of them is at the vicinity of the wire and undergoes the mechanical vibrations due to the magnetic force between the wire and the microbeam. The movement of the microbeam while it is generating a magnetic field induces a current inside another microbeam, which is stationary, as the output signal of the current sensor. In the second configuration, a single composite piezoelectric microbeam is used. The magnetic force between the wire and the piezoelectric microbeam leads the piezoelectric microbeam to move, thus it produces a voltage. Both configurations present extremely low power consumption, which is not dependent on the sensitivity of the current sensors. The dynamic response, sensitivity and power consumption of the current sensors are investigated, compared and discussed.
