Abstract: A bio sensor using electromagnetic waves according to an embodiment may comprise a resonator assembly, a power supply unit, and a processor. The resonator assembly may include at least one feeding line which is disposed along the outer edge of a feeding area and can feed electric power to the feeding area, and a pattern wire which is disposed along a pattern in the feeding area and can receive electric power from the feeding line through capacitive coupling. The power supply unit may supply electric power to the resonator assembly. While a frequency of the electric power is swept, the processor may acquire a parameter which is biometric data corresponding to a concentration of a target analyte existing around the resonator assembly and is related to a resonant frequency of the resonator assembly.

Abstract: In a multi-channel resistance-based gas sensor system, the multi-channel array includes gas sensor channels respectively connected to resistive type gas sensors. The pre-processing unit selects one of a current mode, a resistance mode, and an external resistance mode, analyzes a sensing value obtained from any one of the gas sensor channels based on the selected mode and outputs a voltage value corresponding thereto. The ADC converts the voltage value to digital data. The control unit controls the pre-processing unit to execute one of the current mode for analyzing a sensing value smaller than or equal to a preset first resistance value, the external resistance mode for analyzing a sensing value greater than or equal to a preset second resistance value greater than the preset first resistance value and the resistance mode for analyzing a sensing value between the preset resistance first value and the preset second resistance value.
