Communication system and wearable device and communication method thereof

A wearable device for interacting with a contact lens element, wherein the wearable device is a head mounted communication device, comprising:

• a transceiver circuit, comprising a wireless communication circuit and a wireless charge circuit;
• a first metal structure, coupled to the wireless communication circuit, wherein the first metal structure is configured to communicate with the contact lens element;
• a second metal structure, coupled to the wireless charge circuit, wherein the second metal structure is configured to provide electric power for the contact lens element;
• and
• a reflector, disposed adjacent to the first metal structure and the second metal structure, so as to reflect radiation energy from the first metal structure and the second metal structure.

A communication method, comprising the steps of:

• providing a wearable device, wherein the wearable device is a head mounted communication device, wherein the wearable device comprises a transceiver circuit, a first metal structure, a second metal structure, and a reflector, wherein the transceiver circuit comprises a wireless communication circuit and a wireless charge circuit, wherein the first metal structure is coupled to the wireless communication circuit, wherein the second metal structure is coupled to the wireless charge circuit, and wherein the reflector is adjacent to the first metal structure and the second metal structure;
• using the first metal structure to communicate with a contact lens element;
• using the second metal structure to provide electric power for the contact lens element;
• and
• using the reflector to reflect radiation energy from the first metal structure and the second metal structure.
