Ultra-low-energy operation of electromagnetic bi-stable actuator under restricted energy supply

The research team, co-led by Professor Jun Young Yoon and Woochul Kim from the Department of Mechanical Engineering (co-first authors of this study are Eun Kyu Kim and Jiyong Kim), has developed ultra-low-energy operation method of an electromagnetic bi-stable actuator under restricted energy supply.
Utilizing the proposed high-efficient voltage step-up converter and the energy-saving actuator control method, the research team has demonstrated the energy-efficient operation of the bi-stable actuator which is solely driven by body-heat energy recovery, showing significant potential for self-powered wearable healthcare applications.
This research has been accepted in the renowned international academic journal 'Sensors and Actuators:A. Physical' in August 2024.
