摘要： Aspects are generally directed to a compact and low-noise electric field detector, methods of operation, and methods of production thereof. In one example, an electric field detector includes a proof mass, a source of concentrated charge coupled to the proof mass, and a substrate having a substrate offset space defined therein, the proof mass being suspended above the substrate offset space. The electric field detector further includes a sense electrode disposed on the substrate within the substrate offset space and proximate the proof mass, the sense electrode being configured to measure a change in capacitance relative to the proof mass from movement of the proof mass in response to a received electric field at the source of concentrated charge. The electric field detector includes a control circuit coupled to the sense electrode and configured to determine a characteristic of the electric field based on the measured change in capacitance.

摘要： Aspects are generally directed to a compact and low-noise magnetic field detector, methods of operation, and methods of production thereof. In one example, a magnetic field detector includes a proof mass, a magnetic dipole source coupled to the proof mass, and a substrate having a substrate offset space defined therein, the proof mass being suspended above the substrate offset space. The magnetic field detector further includes a sense electrode disposed on the substrate within the substrate offset space and positioned proximate the proof mass, the sense electrode being configured to measure a change in capacitance relative to the proof mass from movement of the proof mass in response to a received magnetic field at the magnetic dipole source. The magnetic field detector includes a control circuit coupled to the sense electrode and configured to determine a characteristic of the magnetic field based on the measured change in capacitance.
