Problems solved by technology
For example, the positions of the pasted electrode pads are different, or the pasted electrode pads are not firm, loose or fall off, which will cause the received electromagnetic wave signal to be interfered, and thus cannot accurately and truly reflect the lesions in the biological tissue

The embodiment of the invention discloses a signal detection device and method. The device comprises a fixing band and a differential amplification circuit, wherein a plurality of electrode plates are arranged on the inner side of the fixing band; at least one electrode plate serves as an emitting electrode plate, at least two electrode plates serve as two receiving electrode plates, and the two receiving electrode plates are connected with two input ends of the differential amplification circuit respectively; all the electrode plates are arranged on the inner side face of the fixing band, and the distribution shape of the electrode plates on the fixing band is matched with the shape of at least one skull suture in the skull of a detected object. When the device is used for detecting conditions in the brain and the positions of the electrode plates on the inner side of the fixing band are matched with the position of the skull suture of the brain, received electromagnetic wave signals are clearer and are then processed through the differential amplification circuit, interference signals loaded on the electrode plates are eliminated, and the conditions in the skull can be reflected more accurately.
Description
technical field [0001] The invention relates to the technical field of signal detection, in particular to a signal detection device and method. Background technique [0002] Electromagnetic wave signals can propagate energy in the form of waves in the medium, and electromagnetic wave signals of the same frequency have different waveforms when propagating in different media. Therefore, electromagnetic wave signals can be used to distinguish different media. Usually, the method of using electromagnetic wave signals to distinguish different media mainly includes the following steps: first, transmit an electromagnetic wave signal of the same frequency to each type of medium to be tested, so that the electromagnetic wave signal propagates in the material to be tested; After measuring the substance, it receives it; finally, compares the similarities and differences between the received electromagnetic wave signals, thereby distinguishing different types of media.
