A headphones device monitoring human body temperature and pulse wave

Objective： Temperature parameter is one-of-the important indexes of human body system function. So designing a signal of auxiliary device installed in the headset which can independently real-time monitoring the human body temperature and pulse wave is necessary for user. Methods： Pulse wave signal was collected by reflection type pulse wave optical current transducer, and temperature signal was collected by thermopile infrared temperature sensor. Pulse signals, after filtered, enlarged and A/D converted, was transformed into SCM which in headset and computed heart rate and temperature data by digital processing pulse wave and temperature signal. Processing and storing signal and data, finally the treatment of pulse waveforms, heart rate and temperature data is displayed on the LCD screen of the supporting device, and transmission and storage by the supporting device in the SD card interface data. Results： After the actual test, the sensor can be measured by ear temperature and pulse wave, and output them. The headphone has the function of measuring the pulse, temperature and heart rate. Conclusion： A headphones device monitoring human body temperature and pulse wave can provide a real-time detection of the portable device of the pulse wave and heart rate.
