Problems solved by technology

[0004] The above-mentioned multi-dimensional acceleration sensors based on capacitive, piezoresistive and photoelectric types mainly realize six-dimensional acceleration sensors by acquiring the displacement of a single inertial mass connected to the housing by the elastic unit and the damping unit relative to the housing or the strain of the elastic unit. , both have the disadvantages of complex structure and high manufacturing process requirements, and cannot simultaneously measure the linear acceleration and angular acceleration of the moving object

Abstract

The invention discloses an artificial-cilia-based simulated-cochlea-semicircular-canal-contained rotation acceleration sensor comprising more than one hollow bending pipeline. Two ends of the pipeline are communicated with a sealed container; and the pipeline and the container are filled with insulating liquid. More than one protruding fiber unit is arranged on a crista ampullaris part inside each pipeline. According to the invention, the sensor is divided into three units distributed in a space coordinate system layout, thereby sensing rotation at different direction. When the overall sensor is rotated, the fiber units at three directions are deformed differently; and because of different electrode positions, charges or voltages generated on the electrodes are different. Therefore, the direction and value of the multi-dimensional rotation accelerated speed can be determined by analyzing polarity and values of three fibers by a charge amplifier and a processing unit.

Description

technical field [0001] The invention belongs to the acceleration sensor technology, in particular to an artificial cilium imitation cochlear semicircular canal rotation acceleration sensor. Background technique [0002] As an important branch of sensors, acceleration sensors are mainly used in control systems and detection systems, and are widely used in aerospace, weapon systems, automobiles, consumer electronics, etc. Acceleration sensors can be divided into single-dimensional and multi-dimensional acceleration sensors according to the measured dimensions. The current single-dimensional acceleration sensor is quite mature, there are many varieties, and it has been commercialized. Multi-dimensional acceleration sensors, because they can accurately and sensitively respond to changes in the movement of objects, have broad application prospects in industrial automation systems, transportation tools, and navigation and guidance equipment. [0003] In 2012, Wang Zhijun publish...
