The systems and methods described provide for a magnetometer device that includes a resonating element having an inner wire enclosed in a shielding electrode. The shielding electrode decreases the effect of interference on the resonating element. A sensing electrode is disposed proximate to the resonating element. The device further includes a source for generating current that is connected to the resonating element. The current when applied through the inner wire causes a displacement of the resonating element. The magnetometer device measures a magnetic field of the resonating element as a capacitance variation between the shielding electrode and the sensing electrode. The systems and methods herein provide for an accelerometer device that includes a resonating element having an inner core of dielectric material enclosed in a shielding electrode. The accelerometer device measures an acceleration of the resonating element as a capacitance variation between the shielding electrode and the sensing electrode.
