Embodiments of the invention include a current sensing device for sensing current in an organic substrate. The current sensing device includes a released base structure that is positioned in proximity to a cavity of the organic substrate and a piezoelectric film stack that is positioned in proximity to the released base structure. The piezoelectric film stack includes a piezoelectric material in contact with first and second electrodes. A magnetic field is applied to the current sensing device and this causes movement of the released base structure and the piezoelectric stack which induces a voltage (potential difference) between the first and second electrodes.
