Haptic feedback fiber body, haptic feedback fabric and wearable device

초록

Provided are a haptic feedback fiber body, a haptic feedback fabric, and a wearable device. The haptic feedback fiber body can include a core fiber having a first electrode to surround the outer surface thereof, and a vibrating fiber, provided so as to intermittently contact the outer surface of the core fiber, including a second electrode on the inner surface thereof, wherein a piezoelectric polymer is provided on the outer surface of the first electrode or on the inner surface of the second electrode to generate fretting vibrations when the polymer is in close contact with the first electrode or the second electrode on which the piezoelectric polymer is disposed opposite to each other.
