Claim 17:
18. The MEMS device of claim 17, further comprising a second cantilevered member that protrudes from the side surface, the second cantilevered member includes:
a second free end at which the second cantilevered member terminates;
a second piezoelectric layer including a fifth surface, a sixth surface opposite to the fifth surface, a third sidewall extends from the fifth surface to the sixth surface and is transverse to the fifth surface and the sixth surface, and a fourth sidewall extends from the fifth surface to the sixth surface, is transverse to the fifth surface and the sixth surface, and is opposite to the third sidewall, the second piezoelectric layer extends from the side surface of the semiconductor substrate to the second free end;
a third collector layer on the third sidewall, the third collector layer extends from the side surface of the semiconductor substrate to the second free end;
a fourth collector layer on the fourth sidewall, the fourth collector layer extends from the side surface of the semiconductor substrate to the second free end;
a third sub-portion on the third collector layer; and
a fourth sub-portion on the fourth collector layer.
