Sensing electrodes (20B) sense a change in capacitance indicative of vibration modes of resonance of the ring (14) so as to sense motion. A plurality of silicon support rings (16) connect the substrate (12) to the ring (14). The support springs (16) have portions (B1 and B2) are located at an angle to substantially match a modulus of elasticity of the silicon, such as about 22.5° and 67.5°, with respect to the crystalline orientation of the silicon. Also disclosed is a method of making a silicon integrated sensor.

    Abstract: A motion sensor (10) includes a micromachined sensing structure and a number of capacitive electrodes (20) disposed about a periphery thereof. The sensing structure includes a ring (14) supported above a substrate (12) so as to have an axis of rotation normal to the substrate (12), and a number of springs (16) attached to a post (18) positioned at the center of the ring (14). Certain diametrically opposed ones of the capacitive electrodes (20) are configured as drive electrodes (20a), and other diametrically opposed ones of the capacitive electrodes (20), positioned 90 degrees relative to the corresponding drive electrodes (20a) are configured as sense electrodes (20b). Signals produced at the opposed sense electrodes (20b) are conditioned and coupled to a common input of an amplifier circuit (64,70). With the configuration of the drive (20a) and sense (20b) electrodes and supporting circuitry (60-70), the resulting sensor (10) is operable to reject the effects of linear forces thereupon due to road vibrational effects.
