Abstract
A contact lens device includes a hydrogel substrate, a first conductive element, a second conductive element, an EO (Electro-Optical) crystal element, a light source, a light waveguide, a light sensor, and a processor. The first conductive element is disposed on the hydrogel substrate. The second conductive element is disposed on the hydrogel substrate. The EO crystal element is disposed between the first conductive element and the second conductive element. The EO crystal element is affected by a human electric field. The light source transmits an incident light signal. The EO crystal element transmits back a reflected light signal according to the incident light signal. The light waveguide respectively guides the incident light signal and the reflected light signal. The light sensor receives the reflected light signal from the light waveguide. The processor can obtain the relative information of the human electric field according to the reflected light signal.
