Abstract
This disclosure relates to systems and methods for monitoring a wearer’s heartbeat using smart glasses configured to detect pulsations of a temporal artery located near a temple region of the head. A sensing component embedded within a temple arm of the smart glasses includes a capacitive sensing assembly configured to detect deformation of a soft temple material caused by arterial pulsation or an accelerator chip, for example, inertial measurement unit (IMU) configured to capture vibration. Changes in capacitance resulting from the deformation generate an analog electrical signal corresponding to the wearer’s heartbeat. The analog signal is conditioned by a signal processing circuit and converted into digital samples by an analog-to-digital converter (ADC) sampling at a predetermined frequency. A processing unit analyzes the digital samples using signal processing techniques, including filtering, spectral analysis, and peak detection, to extract heartbeat patterns and compute heart rate values such as beats per minute (BPM). In some implementations, machine learning techniques may be used to distinguish heartbeat signals from motion artifacts. The computed heart rate may be displayed through a smart glasses interface or transmitted to external devices via a wireless communication module. By leveraging the natural placement of smart glasses near the temporal artery, the system enables unobtrusive and continuous heart rate monitoring. For example, a user wearing smart glasses during daily activities can have their heart rate continuously monitored without using a separate wearable device. When the glasses are worn, the sensing component located in the temple arm detects pulsations of the temporal artery. The system processes the detected signals to determine the user’s heart rate, which can be displayed through the smart glasses interface or transmitted to a connected smartphone or health monitoring application. This allows the user to conveniently monitor heart rate during activities such as walking, working, or exercising.
