1. A detection device for detecting an eyeball, and comprising:
a frame element;
a transceiver, disposed on the frame element, and transmitting a first RF (Radio Frequency) signal; and
a contact lens element, comprising a resonator, wherein the resonator converts the first RF signal into a first ultrasonic signal, and the first ultrasonic signal is transmitted to the eyeball;
wherein the resonator further converts a second ultrasonic signal from the eyeball into a second RF signal, and the transceiver further receives the second RF signal,
wherein the resonator comprises:
an antenna element, comprising a first radiation metal element and a second radiation metal element; and
a piezoelectric layer, disposed between the first radiation metal element and the second radiation metal element.
