Claim 8:
9. An electronic system, comprising:
one or more MEMS devices, each of the one or more MEMS devices including:
a semiconductor substrate including a main surface extending perpendicular to a first direction and a side surface extending on a plane parallel to the first direction and to a second direction, the second direction being perpendicular to the first direction; and
at least one cantilevered member protruding from the side surface of the semiconductor substrate along a third direction perpendicular to the first and second directions, the at least one cantilevered member comprises:
a body portion including:
a piezoelectric material having a first sidewall and a second sidewall opposite to the first sidewall;
a first collector layer on a first sidewall of the piezoelectric material;
a second collector layer on a second sidewall of the piezoelectric material;
a length along the third direction;
a height along the first directions; and
a width along the second direction, the width being less than the height;
a first sub-portion extends outward from the first collector layer and is on the first collector layer, and the first sub-portion is fully separated from the piezoelectric material by the first collector layer; and
a second sub-portion extends outward from the second collector layer and is on the second collector layer, and the second sub-portion is fully separated from the piezoelectric material by the second collector layer; and

wherein the at least one cantilevered member being configured to vibrate by lateral bending along a direction perpendicular to the first direction.
