    Abstract: A novel Si MEMS piezoresistive resonator is described. The resonator has a shape of a frame, such as a ring or a polygon frame, which has two or more anchors. Electrodes located at the outer or inner rim of the resonant structure are used to excite the structure electrostatically into resonance with a desired mode shape. One or plurality of locally doped regions on the structure is used for piezoresistive readout of the signal. In the most preferred embodiments, the structure is a ring, which has four anchors, two electrodes and four piezoresistive regions at different segments of the structure. The piezoresistive regions are alternatively located at the outer rim and inner rim of the structure in such a way that the piezoresistive signals of the same sign from different regions can be collected. Advantages of this device are large readout signal, large electrode area, robustness, suppressed out-of-plane vibration and larger usable linear range.

    Abstract: Consistent with an example embodiment, devices comprise sensor arrangements with field detectors for detecting components of magnetic fields in planes of the field detectors. The sensor arrangements further include movable objects for, in response to tilting movements, changing at least parts of the components of the magnetic fields in the planes of the field detectors so that the sensor arrangements are made less sensitive to in-plane stray fields by providing the field detectors with saturated field-dependent elements. The movable object may comprise a movable field generator for generating the magnetic field, or the movable object and the field generator may be different objects. The magnetic field is such that the field-dependent element is saturated. The field generator is smaller than the field detector, and the movable object is larger than the field detector, to reduce alignment problems. The movable object has a pivoting point close to the field detector.
