Health Monitoring Based on Bone Conduction Headphones

With the continuous expansion of the headphone market size, headphones have already been combined with other functions, such as health monitoring and massage. In existing technology, air conduction headphones have already been linked with biosensors as a kind of in-ear device to monitor health. However, there are some problems when using this kind of headphones. There will be many discomforts when wearing this headphone for a long time. What is more, detected data will not be higher than out-ear device. Therefore, bone conduction headphones are proposed to be combined with biosensors for health monitoring for more comforts and higher accuracy. This article mainly compares existing device (in-ear device) with imagined device to verify the rationality of using bone conduction headphones. In addition, the principles of biosensors and anatomical mechanism are listed aiming to illustrate why there is more accurate data when using bone conduction headphones for health monitoring. A new kind of algorithm used for signal processing is also listed for eliminating external noise. Finally, a kind of bone conduction headphone which is combined with biosensors to monitor health is proposed. At the same time, the schematic diagram of sensor system that is composed of integrated sensor and integrated circuit is given. Then, the application scenario of this device is discussed and this headphone is advised to be applied in medical field and long-time monitoring field. Eventually, the perspective of materials is discussed to further improve the accuracy and comfort in the future.
