Design of Selectively Controllable Micro Actuators Powered by Remote Resonant Magnetic Fields

摘要: Micro actuators for tiny robots could lead to revolutionary advances in many cutting-edge applications (e.g. minimally invasive medicine). Many prototypes were hence developed, which powered either by micro organism, onboard mechatronic systems or remote magnetic fields. This paper presents two evolving designs, aiming at fabricating can be selectively controlled weak resonant The core concept is design a spring-mass structure convert the vibrations of soft magnets into rotary outputs. fabricated then drive propellers revolute joints locomotion manipulation tasks. proposed designs essentially directly harvest energy perform mechanical work, avoiding complex system components from traditional motorized actuation units, such as windings, commutators, batteries, etc.
