AI Technical Summary
Existing three-dimensional acceleration and force composite sensors are bulky, making them unsuitable for high-temperature, high-pressure, strong-radiation, and corrosive environments, and they lack stability under extreme conditions.
The device employs a flat design, integrating longitudinal and shear effect sensing elements coplanarly. Combined with an insulating ring and pre-compression structure, it utilizes lithium niobate crystal wafers and piezoelectric ceramic wafers as detection elements. The outer sleeve is welded and sealed, simplifying signal transmission and enabling single-layer three-dimensional detection.
Significantly reducing sensor thickness allows for installation in confined spaces, improves detection accuracy and stability, reduces costs, enhances environmental adaptability and shock resistance, and avoids signal interference.
