1. A directional acoustic sensor comprising:
a support comprising a first support portion and a second support portion that are separated from each other and face each other;
a plurality of first resonators extending in a length direction thereof from the first support portion of the support, each first resonator of the plurality of first resonators comprising:
a first end fixed to the first support portion and having a first width at a position where the first end is fixed to the first support portion;
a base and a frame extending from the first end, wherein the frame extends to a first height and the base has a thickness that is less than the first height; and
a second end opposite the first end that is fixed to the first support portion and having a second width less than the first width; and
a plurality of second resonators extending in the length direction thereof from the second support portion of the support and facing the plurality of first resonators, each second resonator of the plurality of second resonators comprising:
a first end fixed to the second support portion and having a third width at a position where the first end is fixed to the second support portion;
a base and a frame extending from the first end, wherein the frame extends to the first height and the base has a thickness that is less than the first height; and
a second end opposite the first end that is fixed to the second support portion and having a fourth width less than the third width,
wherein, in a first resonator arrangement of a region where the plurality of first resonators and the plurality of second resonators face each other, the second ends of the plurality of first resonators and the second ends of the plurality of second resonators form an intersecting structure.
