1. An electric energy generator system comprising:
- an ultrasonic-wave emission device configured to generate an ultrasonic-wave and emit the ultrasonic-wave; and
an electric energy generator device configured to generate an electric energy upon a receipt of the emitted ultrasonic-wave,wherein the electric energy generator device comprises;
a substrate;
an electrode on the substrate;
a first friction-charged member on the electrode;
a spacer disposed on the substrate and configured to surround the electrode and the first friction-charged member; and
a second friction-charged member disposed on the spacer to be spaced from the first friction-charged member,wherein the second friction-charged member repeatedly contacts or is separated from the first friction-charged member, andwherein a closed inner space is defined between the first friction-charged member and the second friction-charged member and the spacer.
