Embodiment Construction

[0050] The object of the present invention is to provide a flexible optical fiber sensing membrane 113 for measuring the respiration rate, heart rate, activity and presence of the human body. Such as figure 2As shown, the flexible fiber optic sensing film 113 is composed of an interlayer 114 and an optical fiber 115 . Optical fibers 115 are housed in the interlayer 114 . A mat comprising a flexible fiber optic sensing film 113 , a programmable LED driver 110 , a light source 111 and a light sensor 112 . The output end of the programmable LED driver 110 is connected to the light source 111 , the light source 111 is connected to one end of the optical fiber 115 , and the other end of the optical fiber 115 is connected to the light sensor 112 . The control signal drives the programmable LED driver 110 for providing LED current to the light source 111 . The light source 111 generates light under the driving of the LED current and enters the optical fiber 115 . The optical sen...

Abstract

The invention provides a flexible optical fiber induction film, and also discloses a pad comprising the film, and an application method. The film (113) comprises an interlayer (114) and an optical fiber (115) disposed in the interlayer (114). The film (113) also comprises a projection (142) which is close to the optical fiber (115) and is disposed in the interlayer (114). The film (113) is used for generating light loss in the optical fiber (115) when a person lies on the film (113) and moves. The film is safe and comfortable for a person.

Description

technical field [0001] The invention relates to the field of optical fiber sensing films, in particular to a flexible optical fiber sensing film, a mat containing the film and a method of use thereof. The flexible optical fiber sensing film can be used to detect single or multiple vital signs of a human body. Background technique [0002] Currently, piezoelectric sensors are used to detect the breathing rate, heart rate, and activity of a human being sleeping on a bed or mattress. Typically, piezoelectric sensors are mounted on the surface of the sensing mat and embedded in the bed or mattress. Piezoelectric transducers have very high DC output impedance and can be modeled as a ratiometric power supply and filter network. Such as figure 1 As shown, the output voltage is directly proportional to its applied force, compression or tension. Due to the piezoelectric sensor material, the output voltage range varies with respect to tension / compression. Piezoelectric sensors can...
