1. An ultrasonic triboelectric generating device, comprising:
a power generating device module comprising:
a lower electrode; and
a first friction member disposed on the lower electrode;
a matching layer disposed on the first friction member; and
a titanium package disposed to surround an outer periphery of the power generating device module, wherein the titanium package is attached to an upper portion of the matching layer and surrounding the matching layer,
wherein the matching layer includes a fluid, is configured to function as an upper electrode, and
wherein when an external ultrasonic wave is applied to the matching layer, displacement of the matching layer occurs only on a surface facing the lower electrode to have the power generating device module generate triboelectric electricity,
wherein the titanium package includes:
an upper housing disposed to surround an upper portion and a side portion of the power generating device module and attached to a side of the matching layer; and
a lower housing partially inserted to the upper housing to surround a lower portion and the side portion of the power generating device module; and
a spacer provided between the upper housing and the lower electrode,
wherein the spacer includes:
a lower supporting member positioned between the first friction member and the lower electrode;
an upper supporting member positioned between the first friction member and the upper housing; and
a connection member disposed at least partially penetrating the first friction member to connect between the lower supporting member and the upper supporting member.
