1. A triboelectric nanosensor, comprising:
an elastic body, comprising:
an inner wall surrounding a chamber; and
a plurality of biomimetic shark placoid scale-shaped microstructures adjacent to each other and disposed at least one portion of the inner wall;
a liquid metal located within the chamber and surrounded by the elastic body; and
a wire electrically connected to the liquid metal;
wherein the elastic body is pressed to be deformed and restores to change a contact state between the liquid metal and the biomimetic shark placoid scale-shaped microstructures, thereby allowing a plurality of electrons to flow into the liquid metal via the wire or to flow out from the liquid metal via the wire.
