Abstract
Disclosed is a flexible tactile actuator including a tactile transmitter configured to be flexible and including magnetic particles capable of being polarized in response to an external magnetic field and a matrix layer including the magnetic particles, a magnetic field generator disposed below the tactile transmitter and configured to generate a magnetic field in the tactile transmitter, and an elastic member provided in a shape of a film, having at least a portion in surface contact with the magnetic field generator, and attached to be in surface contact with one of a top surface and a bottom surface of the tactile transmitter.
Claims20
A tactile actuator comprising:
- a tactile transmitter containing magnetic particles;
- a magnetic field generator configured to apply a magnetic field to the tactile transmitter;
- and
- an elastic member connected to the tactile transmitter and disposed between the tactile transmitter and the magnetic field generator,
- wherein, as the magnetic field generator applies or does not apply a magnetic field to the tactile transmitter, at least a portion of the tactile transmitter moves relative to the magnetic field generator, thereby generating a vibrating force of 0.2 G or more.
A tactile actuator comprising:
- a tactile transmitter containing magnetic particles;
- a magnetic field generator configured to apply a magnetic field to the tactile transmitter;
- and
- an elastic member connected to the tactile transmitter,
- wherein a distance between the tactile transmitter and the magnetic field generator ranges from 0.1 mm to 3 mm, and
- wherein, as the magnetic field generator applies a magnetic field to the tactile transmitter, at least a portion of the tactile transmitter moves relative to the magnetic field generator.
A tactile actuator comprising:
- a tactile transmitter containing magnetic particles;
- a magnetic field generator configured to apply a magnetic field to the tactile transmitter;
- and
- an elastic member connected to the tactile transmitter,
- wherein a content of the magnetic particles relative to a volume of the tactile transmitter ranges from 4 vol % to 60 vol %,
- wherein the tactile transmitter and the magnetic field generator is spaced apart from each other, and
- wherein, as the magnetic field generator applies a magnetic field to the tactile transmitter, at least a portion of the tactile transmitter moves relative to the magnetic field generator.
