본고에서는 WiFi, ZigBee, 블루투스 등 무선 통신 기술을 이용해서 로봇, 헬스케어, 스마트그리드, 자율자동차 분야 등에서 무선에 의한 센싱 및 전력 전송을 제어하는 시스템에 대해서 기술하였다. 최근에 사물인터넷 (Interne of Things) 및 사물통신(Machine to Machine)을 이용한 다양한 응용이 많은 분야에서 제기되고 있으며 이를 위해서는 제어, 컴퓨팅, 네트워킹 기술이 융합된 기술을 요구한다. 기존의 제어 중심이었던 임베디드 시스템에 유무선 통신망을 이용한 컴퓨팅 기술이 융합된 가상물리 시스템(Cyber Physical System)이 미국 및 유럽에서 향후 국가 주도 기술로 채택되어 연 산 학이 협력하여 추진 중이다. 본고에서는 이러한 기술 개념에 일치하는 무선을 이용한 센싱에 의해 무선으로 전력을 전송하는 시스템을 제어하는 기술을 구현하고 기술하였다.
