1. A photoacoustic, noninvasive, and continuous blood glucose measurement device, comprising:
a diode laser for irradiating a living body with a pulsed laser signal having a specific wavelength;
an ultrasound transducer for measuring a photoacoustic signal in a form of ultrasonic waves generated by a reaction of the living body with the pulsed laser signal;
a contact part configured to contact part of a living body;
a medium part disposed between the contact part and the ultrasound transducer, and configured to transmit the pulsed laser signal and the photoacoustic signal therethrough; and
an optical fiber for passing through the ultrasound transducer to be connected to the diode laser,
wherein the diode laser and the optical fiber are disposed outside of a steering wheel of a vehicle and in at least one of a gearshift lever, an armrest, a headrest, or a rear seat, and
the ultrasound transducer, the medium part, and the contact part are mounted inside the steering wheel of the vehicle.
