전자기장(電磁氣場, Electromagnetic field)을 이용하는 무선전력 전송기술은 오래전부터 관련 연구가 시작되었다. 최근 스마트폰의 새로운 시장발굴을 위한 산업체의 노력과 새롭고 편리한 기능을 요구하는 소비자의 욕구를 충족시키는 해법 중 하나로 무선전력 전송기술을 이용한 무선충전 기술이 관심을 받기 시작하면서 다양한 스마트기기에 적용되고 있다. 또한, 무선충전 기술이 적용 가능한 웨어러블 기기와 IoT 기기, 그리고 전기자동차 시장의 확대가 기대되고 있어 수년 내 무선충전 기술은 현재보다 빨리 높은 수준에 도달할 것이며, 산업체의 시장선점과 표준화 경쟁이 치열할 것으로 예상된다. 본고에서는 이러한 무선충전 기술의 발전 동향과 표준화 동향을 소개하고, 향후 무선충전 기술의 발전 방향에 대해 논하고자 한다.
