Design and implementation electronic stethoscope on smart chair for monitoring heart rate and stress levels driver

SHESOP is an intelligent health system designed to monitor health condition of the user and provide information from the data saved in system. SHESOP integrate three subsystems such as web, mobile and wearable devices. One of implementation SHESOP system applied on smart chair in car aims to monitor heart rate and stress level of the driver. Implementation of the system in the car will provide convenience to the driver to take a decision on the way by the condition of the driver's heart health. Electronic stethoscope utilizes a microphone and an electronic circuit as an amplifier and signal conversion of acoustic signals into digital. To facilitate physicians in analyzing the status of the heart, the output can be visualized in the form of spectrum and stored into a digital audio format. Results of analyzed heart sounds can determine the condition of the driver's heart health and stress levels using heart rate variability (HRV) method. The parameters used in the processing using time domain series. An assessment of the condition of heart health and stress level indicators based on standard SDNN.
