ARRANGEMENT OF PIEZO-SENSORS IN ACCELEROMETER |
摘要 |
<p>An accelerometer (102) senses acceleration in a specific direction through the voltages produced by multiple piezoelectric sensors (114, 302, 304) electrically arranged in parallel in response to the acceleration. The main axes of sensitivity of the piezoelectric sensors are aligned and point in the same direction. The parallel arrangement enables to control the thermal noise level of the output signal of the accelerometer that originates in a bias resistor (116) connected in parallel to the parallel arrangement of the piezoelectric sensors.</p> |
