    摘要： An acceleration sensor includes a weight and a vibrator that supports the weight at its center of gravity. When acceleration is applied to the weight, stress equivalent to the applied acceleration is generated in the vibrator. As the vibrator is arranged to support the weight at its center of gravity, a characteristic relationship is observed between the acceleration, such as angular acceleration or translational acceleration, and the size of electric charges and the polarity. By taking advantage of this relationship, different types of acceleration can be easily detected.

    摘要： An acceleration sensor that suppresses fluctuations in the offset voltage and with an enhanced temperature characteristic is provided. The acceleration sensor comprises an weight that is formed in the center of a semiconductor substrate; a frame that is formed at the circumference of the weight; a beam or diaphragm that connects the weight and frame; a detection element that is formed on the beam or diaphragm and which detects bending of the beam or diaphragm that corresponds with the applied acceleration; and a lead that is formed on the beam or diaphragm and which guides the detection output of the detection element to a pad that is provided on the frame, wherein a dummy lead comprising a plurality of dot patterns which are at least electrically independent of the lead formed on the beam or diaphragm is formed on the beam or diaphragm.

    摘要： Providing a small-sized acceleration sensor including a vibrator formed of a piezoelectric single crystal, and a weight section connected to the vibrator and supported at a position different from the position of the center of gravity of an assembly of the vibrator and weight section. Two divided electrodes used for detecting an electrical signal are formed on the vibrator and connected to two wiring patterns of the weight section which also functions as a signal detecting substrate, with an anisotropic conductive adhesive. When an acceleration in one direction is applied, an angular moment exerted in the weight section is detected as sliding vibration by the vibrator, and an electrical signal corresponding to the acceleration is output from the electrodes through the wiring patterns.
