Abstract
A smart glasses comprises a glasses body, a vocal unit, a receiving unit, and a control unit. The vocal unit is arranged in the glasses body. The vocal unit comprises a piezoelectric material layer. The piezoelectric material layer is configured to receive drive signals and convert the drive signals into first acoustic signals and/or second acoustic signals. The second acoustic signals are configured to detect vital sign parameters of a human body. The receiving unit is arranged in the glasses body. The receiving unit is configured to receive feedback signals of the human body with respect to the second acoustic signals. The control unit is configured to output the drive signals. The control unit is further configured to determine the vital sign parameters of the human body based on the feedback signals. A wearable system is also provided.
