MRE KINESTHETIC ACTUATOR USING MRE AND ELECTRO-PERMANENT MAGNET

摘要

The present invention relates to a muscle sensory actuator using an MRE and an electromagnet, and more specifically, as a muscle sensory actuator using an MRE and an electromagnet, wherein a solenoid coil is wound, and an electromagnet that forms a magnetic field by power applied to the solenoid coil; It is disposed on the top of the electromagnet and maintains the original soft state when no magnetic field is applied, and changes to a hard state when the magnetic field formed in the electromagnet is applied by power applied to the solenoid coil. -Rheological Elastomer); And a power supply unit for supplying power for forming a magnetic field to the solenoid coil wound around the electromagnet. According to the muscle-sensory actuator using MRE and electromagnet proposed in the present invention, an electromagnet that forms a magnetic field by power applied to a solenoid coil, and an electromagnet that forms a magnetic field in a state where the magnetic field is not applied, maintains the original soft state, and the magnetic field is applied. In this state, the MRE that changes to a hard state and a power supply that supplies power for the formation of a magnetic field to the solenoid coil wound around the electromagnet are included, making it possible to implement a thin, flexible, and durable small muscle sensory actuator. , It can effectively create and deliver soft and hard muscle sensations with the strength that changes according to the presence or absence of a magnetic field applied to the MRE. In addition, according to the muscular sense actuator using the MRE and the electromagnet of the present invention, the strength of the physical properties of the MRE is used as the muscular sense through the magnetic field generated from the electromagnet wound around the solenoid coil, so that a simple structure and miniaturization of the muscular sense actuator is possible, It is easy to control the driving of muscle sensation, and it can be applied optimally to smart devices that are miniaturized by multifunctionalization. In addition, according to the muscle-sensory actuator using the MRE and the electromagnet of the present invention, the electromagnet that forms a magnetic field is composed of an electro-permanent magnet whose NS polarity is changed by the applied power source, so that even if the magnetic field of the solenoid coil disappears, the electro-permanent magnet As the magnetic field of is maintained as it is, power consumption of the muscle sensory actuator for generating muscle sensory can be reduced.
