This invention relates to the field of sensing materials technology, specifically disclosing a cellulose-based conductive hydrogel material for ascorbic acid detection, its preparation method, and its applications. This hydrogel uses TEMPO oxidized cellulose nanofibers (TOCNF) as a biocompatible matrix. By introducing Cu-BTC / CNT composite nanoparticles, a three-dimensional conductive network with both high electrochemical activity and structural stability is constructed. While retaining the biocompatibility and flexibility of cellulose, it exhibits particularly high sensitivity and selectivity in detecting small biomolecules such as ascorbic acid, with short response time and good stability. This method achieves synergistic optimization of the composite material's structural uniformity and functionality without relying on complex molding processes. Experimental results show that the conductive hydrogel prepared by this invention possesses good mechanical properties and biocompatibility, exhibiting high sensitivity and stability in biosensing fields such as ascorbic acid detection, providing a novel high-performance material basis for flexible biosensors.

This invention relates to the field of audio signal processing technology, specifically to a directional sound pickup and adaptive noise reduction system and method using a multi-microphone array. The invention acquires signals through a multi-microphone array and performs time-frequency conversion. A beamforming unit forms a directional beam according to the target direction and constructs spatial nulls in the interference direction. A noise reduction unit adaptively suppresses noise in the beam output, simultaneously extracting residual noise energy and speech distortion feature values. A closed-loop feedback control unit executes a zero-point adaptive optimization algorithm based on the joint constraints of residual noise energy and speech distortion. Using the aforementioned feature values, a cost factor is calculated and a beam zero-point direction update is generated, which is fed back to the beamforming unit to achieve closed-loop adaptive adjustment of the null direction. This breaks the limitation that traditional beamforming and post-noise reduction are independent, and can simultaneously improve noise suppression capability and speech fidelity in complex acoustic environments.
