AI Technical Summary

Technical Problem

Existing sensing devices are difficult to achieve synchronous integrated measurement of multiple parameters, especially due to limitations in the mechanical-electrical coupling response mechanism. They cannot simultaneously acquire information on elastic modulus and ion concentration or water content. Furthermore, they are complex in structure, difficult to calculate signals, and lack stability, failing to meet the requirements for highly sensitive and stable integrated measurement in complex scenarios.

Method used

Design a multi-parameter integrated sensing and measurement device, including a hollow dome support unit, a first electrode layer, an elastic force transmission unit, a cross force transmission unit, and a controller. Ion concentration, elastic modulus, and pressure signals are acquired through a capacitance channel, a modulus channel, and a pressure channel, respectively. Structural isolation, electrical channel separation, and time-division acquisition strategies are adopted to avoid signal crosstalk and achieve synchronous detection of multiple parameters.

Benefits of technology

It enables simultaneous detection of pressure, elastic modulus, and ion concentration or water content, improving detection accuracy and stability, simplifying device structure and signal processing, and enhancing the sensitivity and compatibility of sensor measurements.
