Abstract

Wireless emergency call switch used in industry, the most important thing is the sustainable power supply. This paper describes the development and performance test results of a compact electromagnetic energy harvesting mechanism for batteryless wireless switch. This paper summarizes proposed structure design and magnetic field analysis results of the mechanism to generate an induced electromotive force using 2mm stroke of a single push action. This analysis results show the power output of the proposed mechanism up to VDC $4.5V{\pm}25%$ and it can hold up to 65ms of the power generation with greater than 2.5V.

산업현장에서 사용되는 무선 비상호출 스위치의 성공적인 운영을 위해서는 지속적인 전원의 공급이 이루어져야 한다. 본 논문은 배터리가 필요 없는 무선 스위치에 적용할 수 있는 전자기 유도방식의 초소형 에너지 하베스팅 메커니즘 개발 및 구현된 메커니즘의 성능 실험 결과를 보여주고 있다. 연구결과로 단 방향 누름 동작과 2mm 이동거리의 제한조건 내에서, 유도기전력을 생성하는 새로운 메커니즘이 제시됐다. 또한, 구현된 메커니즘의 전자기 유도 발전 출력 성능 실험결과로 VDC $4.5V{\pm}25%$(도달시간 1.2msec), 2.5V 이상 전압의 발전시간이 65ms가 됨을 보여주고 있다.
