Abstract: A multispectral optical sensor is disclosed. In one embodiment, the multispectral optical sensor includes a piezoelectric material, a first sensing layer and a second sensing layer spaced apart from each other on the piezoelectric material and configured to change the propagation speed of the acoustic wave propagated through the piezoelectric material by receiving ultraviolet light and visible light, respectively. The multiple optical sensor further includes a first acoustic wave output part and a second acoustic wave output part disposed on the piezoelectric material respectively corresponding to the first and second sensing layers and configured to generate an electrical signal based on the changed acoustic wave. The multiple optical sensor measures the intensity of ultraviolet and visible light using a single sensor by detecting the change in frequency, and measures the frequency change in the acoustic wave using zinc oxide, gallium nitride), or cadmium sulfide nanoparticles.
