Latest Patents
Takeyari holds a patent for a semiconductor-type three-axis acceleration sensor. This invention features high shock resistance, minimal output differences between the piezo resistors of the X-axis, Y-axis, and Z-axis, as well as compact size, high sensitivity, and substantial output. The design includes a flexible arm composed of flexible widening parts and a flexible parallel part. The flexible widening part is strategically designed with a maximum stress part, where the piezo resistors are arranged on the upper surface of the flexible arm. This arrangement ensures that the terminal of the piezo resistor is positioned at the maximum stress part, optimizing performance. The Z-axis piezo resistors are located near the width centerline of the flexible arm, while the X-axis and Y-axis piezo resistors are positioned away from it. Additionally, the Z-axis piezo resistors are shifted in the longitudinal direction of the flexible arm to minimize output differences among the axes.
