During the sleep, snoring is always happened on some people and the sleep breath disorder is the common disease of snoring people. The researches have identified that sleep breath disorder has highly possibility conducted the high blood hypertension, and thus blood oxygen concentration variation is the important index to detect sleep breath disorder. The purpose of this research is to develop the blood oxygen detection array device for smart oral appliance. It contains two designs. Before the array-type design, the single point detection of oral cavity by using commercial oxygen blood LED emitter/receiver detection device is created to verify the feasibility of proposed design, and then proceed the following two array-type designs. There are two designs for the flexible 3X3 array-type blood oxygen detection. The first array-type design is to use the aluminum wafer as mold by 3D printing, depositing parylene as flexible substrate, fitting emitter/receiver chips, interconnection lines are created by semiconductor process and finally depositing upper parylene film as protection layer. When the upper parylene film is created, the flexible device can easily peel off from the mold. Another method is to use the flip-chip design; the glass plate is used as hard temporary substrate, interconnection lines are created by semiconductor process, flipping the emitter/receiver chips, and finally depositing upper parylene film as protection layer. When the upper parylene film is created, the flexible device can easily peel off from the glass plate. The light sources of emitter are red and infrared in order to measure human blood oxygen concentration. Both design possess are bio-compatible and flexible, the device can be attached to the skin by the same curvature to measure the blood oxygen concentration correctly. By using the devices created by the proposed process to measure blood oxygen concentration on the same people, the blood oxygen concentration of oral cavity is about 92%, and 100% for finger. The difference is pretty close as normal human’s value, and thus the feasibility of research can be approved. The two flexible types are placed on wrist to measure the blood oxygen concentration of radial artery. The results show that only 4 photodiodes among 8 photodiodes can detect the blood oxygen concentration. The possible reasons are the distance between each photodiode and radial artery, and the fitting condition between each photodiode and radial artery. The measurement results can meet the design concept of array-type regardless of the misalignment and fitting condition, only one photodiode can correctly measure the blood oxygen concentration, the goal has reached.
