摘要： A MEMS resonator has a component which provides a capacitance associated with the transduction gap which has a temperature-dependent dielectric characteristic, which varies in the same direction (i.e. the slope has the same sign) as the Young's modulus of the material of the resonator versus temperature. This means that the resonant frequency is less dependent on temperature.

摘要： A device has a micro electromechanical structure (10) with a first arm (102), at least one second arm (104a, b) connected to each other via a connection (100). Both arms (102, 104a, b) and the connection (100) are preferably made of a single crystalline body. The first and second arm (102, 104a, b) have end portions attached to a substrate, but otherwise the arms and their connection are free to move relative to the substrate. The first and second arm (102, 104a, b) extending from the end portions to the connection (100) along different directions, preferably perpendicularly to each other. An electrode (12) is provided on the substrate, adjacent to the micro electromechanical structure (10) to excite vibration of the structure. The two arms in different directions make it possible to reduce the nonlinearity of the stiffness during vibrations of the structure.

Such detection circuits (1) are less sensitive to misalignment of components during an assembly and simpler to produce and less costly. The second detectors (200) are entirely located within the light spot (3) independently from positions of the joysticks and the first and third detectors are partly located within the light spot (3) dependently on positions of the joysticks. The detection units (101) comprise photo diodes (120) and transistors (121) for digitizing the signals from the photo diodes (120).
