Document Type and Number:
WIPO Patent Application WO/2020/149052
Kind Code:
A1
Abstract:
This tactile presentation device is provided with a sheet-like electric field responsive polymer actuator which expands and contracts in a planar direction and a thickness direction in accordance with an applied voltage, wherein a user is caused to perceive vibrations based on the expansion and contraction of the electric field responsive polymer actuator as a tactile sensation. The electric field responsive polymer actuator includes a tactile presenting unit (15a) arranged in a planar shape. On the inside of the tactile presenting unit (15a) there is arranged a sandwiching member for partially restricting expansion and contraction, in the planar direction, of a sandwiched part (P1) of the tactile presenting unit (15a), by sandwiching the tactile presenting unit (15a) against a portion of the body of the user pressing the tactile presenting unit (15a) toward the inside.
