Abstract:
1. A dynamic quantity MEMS sensor comprising: a force receiving portion; a first movable portion that rotates in a first rotational direction around a first rotational axis according to dynamic quantity in a first direction that the force receiving portion receives, and rotates in the first rotational direction around the first rotational axis according to dynamic quantity in a second direction different from the first direction that the force receiving portion receives; a second movable portion that rotates in a second rotational direction around a second rotational axis according to the dynamic quantity in the first direction that the force receiving portion receives, and rotates in an opposite direction to the second rotational direction around the second rotational axis according to the dynamic quantity in the second direction that the force receiving portion receives, a first coupling portion that couples the force receiving portion and the first movable portion; a second coupling portion that couples the force receiving portion and the second movable portion; and a support portion that supports the first movable portion and the second movable portion rotatably around the first rotational axis and the second rotational axis, wherein the first coupling portion and the second coupling portion have a flexible and twistable beam shape, and at least the dynamic quantity in the first direction and the dynamic quantity in the second direction can be detected.
