A multi-channel microfluidic label-free pathogen detection system and method with internal reference correction is disclosed, relating to the field of pathogen detection. The method includes: acquiring the initial interference spectrum of each functional detection region before the reaction; injecting the sample to be tested and distributing it to multiple parallel microfluidic channels according to a preset flow path; specific binding of the target pathogen to the aptamer to form an aptamer-pathogen complex layer; acquiring the post-reaction interference spectrum of each functional detection region, comparing the post-reaction interference spectrum with the initial interference spectrum before the reaction, and calculating the change in optical path difference of each functional detection region; calculating the target detection signal and comparing it with a standard curve to obtain the concentration of the target pathogen in the sample. This invention achieves continuous, accurate, and repeatable spectral acquisition of multiple functional detection regions, without the need for nucleic acid amplification or labeling, realizing multi-channel parallel, automated acquisition, internal reference correction, and quantitative analysis of pathogen concentration, thus improving the accuracy and reliability of the detection results.

This application belongs to the field of collision detection technology, and relates to an array-type force / tactile sensor and a self-moving robot. The array-type force / tactile sensor is installed on the self-moving robot, which includes a base and a side shell. The array-type force / tactile sensor includes M sensing units. The side shell is composed of at least one shell unit, and each shell unit is provided with at least one sensing unit. The sensing unit includes a sensing element and a detection element. One of the sensing element and the detection element abuts against the shell unit and is used to generate a relative displacement relative to the other of the sensing element and the detection element due to collision deformation. The detection element is used to generate a detection signal that changes uniquely with the relative displacement, and the sensing element is used to detect the detection signal. Compared with existing collision detection modules for self-moving robots, the array-type force / tactile sensor of this application can more completely and accurately detect whether a collision has occurred in the self-moving robot.
