AI Technical Summary

Technical Problem

Existing multimodal sensors suffer from low sensitivity, low selectivity, and crosstalk when simultaneously detecting external stimuli, leading to increased signal interference and errors, which affects system performance.

Method used

A dual-modal flexible sensor array mimicking a scorpion pectin is designed, comprising a pectin-like vent plate, a gas-sensitive layer, a pectin-like porous dielectric layer, and a substrate. Specific microstructure and signal transmission channel designs are employed, drawing inspiration from the gas and pressure sensing structures of a scorpion pectin, to achieve independent sensing and transmission of gas and pressure signals.

Benefits of technology

It achieves highly selective and sensitive gas and pressure sensing, reduces signal crosstalk, improves the sensor's detection threshold and operating range, and ensures signal accuracy and independence.
