Description

technical field [0001] The invention relates to the technical field of optical fiber sensing, in particular to a physiological parameter monitoring device based on a neural network-based wearable optical fiber sensor. Background technique [0002] The working principle of the optical fiber sensor is that the change of the external physical quantity can modulate a certain parameter of the light wave transmitted in the optical fiber to make it change accordingly. By detecting the modulated optical signal, the process of demodulating the measured physical quantity is obtained. In the optical fiber sensor, the optical fiber can not only be used as the propagation medium of the light wave, but also the light wave propagating in the optical fiber changes due to the change of external factors, and the optical fiber can also be used as a sensing element to detect such as temperature, vibration, strain, shape, etc. Physical quantity, the detection, intelligent processing and applicat...
