Abstract
Description
technical field
[0001] The invention relates to micro-actuators in the technical field of micro-electro-mechanical systems, in particular to a stepping and micro-rotating device based on electrothermal drive, which is used to convert the reciprocating linear motion generated by the electrothermal actuator into the rotational motion of gears. Background technique
[0002] The actuator is the executive part of MEMS, which undertakes important functions such as energy conversion and motion transmission. According to the energy source, it is divided into electrical energy, chemical energy, fluid energy and thermal energy actuation methods. Electric actuators use electric charge force, magnetic field force, etc. to generate actuation, with fast response speed and low power consumption, but small output displacement and high voltage required, such as piezoelectric, electromagnetic and electrostatic. Due to its low power consumption, high operating frequency, high designability and...
