Abstract

Provided is an electrical stimulus device including a member to be wound around an arm of a user, multiple electrodes arranged on one surface of the member, and multiple optical distance sensors arranged on the one surface of the member. An electrical stimulus signal output from an electrical stimulus generation circuit is provided to the user from a specific electrode of the multiple electrodes to provide a stimulus to a muscle of the arm at a position facing the specific electrode, and the multiple optical distance sensors detect displacement of muscles of the arm. Some electrodes of the multiple electrodes are substantially rectangular electrodes inclined with respect to a circumferential direction of the arm of the user at a predetermined angle of lower than 90°.

Claims

a member to be wound around an arm of a user;

multiple electrodes arranged on one surface of the member; and

multiple optical distance sensors arranged on the one surface of the member,

wherein an electrical stimulus signal output from an electrical stimulus generation circuit is provided to the user from a specific electrode of the multiple electrodes to provide a stimulus to a muscle of the arm at a position facing the specific electrode, and the multiple optical distance sensors detect displacement of muscles of the arm, and

at least one electrode of the multiple electrodes is a substantially rectangular electrode arranged with the substantially rectangular electrode being inclined with respect to a circumferential direction of the arm of the user at a predetermined angle of lower than 90°

.

2. The electrical stimulus device according to claim 1, wherein

the multiple electrodes are separately arranged at at least three locations including a center portion electrode arrangement spot at a specific position of the member, a left portion electrode arrangement spot on a left side of the specific position in the circumferential direction, and a right portion electrode arrangement spot on a right side of the specific position in the circumferential direction, and

at least one electrode arranged at the left portion electrode arrangement spot and at least one electrode arranged at the right portion electrode arrangement spot are substantially rectangular electrodes arranged with the substantially rectangular electrodes being inclined in opposite directions at the predetermined angle.

3. The electrical stimulus device according to claim 2, wherein

the predetermined angle is set to 32°

±

5°

.

4. The electrical stimulus device according to claim 2, wherein

at least one electrode arranged at a center portion of the member is an electrode extending in the circumferential direction of the arm of the user.
