(a) Flexible PCB implementation of our earbud featuring MAX86161 PPG sensor and a co-located ST LSM6DSRX IMU. (b) An in-ear soft earbud was realized by embedding the in-ear flexible PCB board into a transparent silicone mold. (c) Head-worn data acquisition device consisting of an ESP32 microcontroller collecting data from in-ear PPG and IMU sensors in the left and right ear. (d) A participant wearing our earbud-based prototype and taking part in the data collection protocol.
