    Abstract: An ultraviolet-ray (UV) sensor is disclosed. In one embodiment, the UV sensor includes a piezoelectric material, a sensing film arranged on the piezoelectric material and senses ultraviolet rays, an elastic wave input unit arranged on one end of the sensing film on the piezoelectric material and provides the sensing film with an elastic wave generated based on an electrical signal and an elastic wave output unit arranged on the other end of the sensing film on the piezoelectric material and senses a change in frequency of the electrical signal generated based on the provided elastic wave. The UV sensor improves sensitivity of the sensor by enabling the particles having large surface areas due to their characteristics to react with a larger amount of ultraviolet rays. the UV sensor can secure price competitiveness since the UV sensor measures a change in frequency of the elastic wave using zinc oxide (ZnO) nanoparticles.

    Abstract: A multi-channel drug detection method is proposed. The method may include inputting an electrical signal of a frequency included in a search range set in sensors of a sensor board, comparing magnitudes of electrical signals output by the sensors, and determining a frequency having the largest magnitude as a resonance frequency, the inputting, comparing, and determining being repeatedly performed. The method may also include determining, as a first resonance frequency, a resonance frequency determined in the inputting, comparing, and determining performed before a sample is inserted, and inserting the sample into the sensor board. The method may further include determining a second resonance frequency by repeating the inputting, comparing, and determining while moving the search range to search for a resonance frequency. The method may further include determining presence of a target material based on a difference between the first resonance frequency and the second resonance frequency.
