Abstract(in English) | Requirement of miniaturizing and integrating mechanical devices, such as relays, is increasing because of telecommunication society development. Micromachining has been studied as the technology for realizing on-chip micromechanical devices, microrelays, however, have not appeared because micromachining is not suitable for making a magnetic coil structure. We have proposed a coil free magnetic actuator : a thermally controlled magnetization actuator (TCMA) whose actuation is based on reducing the magnetization by local heating. The TCMA microrelay of 2mm^2 has been fabricated by a planar process technology with nickel surface micromachining. In this paper, we explain the principle, the fabrication method and the generated force of the microrelay. An integrated thin film heater could heat to reduce nickel's magnetization, and the microrelay was operated with 50Hz switching motion. |
