Abstract

표면 탄성파 기반 마이크로 센서를 이용한 무선측정장치 및 그 방법이 개시된다. 본 발명의 실시예에 따른 표면 탄성파 기반 마이크로 센서를 이용한 무선측정장치는, 무선으로 수신되는 펄스 신호를 표면 탄성파(SAW : Surface Acoustic Wave)로 변환하고 환경 요소의 변화를 측정하기 위해서 변환된 표면 탄성파를 반사시켜 복수의 펄스 신호들을 발생해서 무선으로 송신하는 SAW 기반 마이크로 센서; 와 환경 요소의 변화를 측정하기 펄스 신호를 발생하여 무선으로 상기 SAW 기반 마이크로 센서로 송신하고, 송신된 펄스 신호가 SAW 마이크로 센서에서 반사되어 수신되는 복수의 펄스 신호들간의 간격이, 설정된 환경 요소의 펄스 신호들간의 간격에 해당될 때마다 펄스 신호를 발생해서 무선으로 SAW 기반 마이크로 센서로 송신하고 일정 시간 동안 펄스 신호의 발생횟수를 카운트하여, 환경 요소의 변화를 측정하는 리더기를 포함한다.
