POWERLESS AND WIRELESS KEYBOARD HAVING ELECTRIC CIRCUIT MADE FROM ORGANIC ELECTRIC CONDUCTOR

摘要

PURPOSE: A powerless and wireless keyboard with electric circuit made of organic electric conductor is provided to improve the flexible performance of the keyboard by implementing a PCB from flexible material and implementing an RFID chip and an antenna which are mounted on the PCB from organic conductive material. CONSTITUTION: A communications chip(301) generates unique key information according to the key button operation of a unit key. An antenna(303) wirelessly transmits the unique key information provided from the communication chip. A PCB(Printed Circuit Board)(300) composes a conductor(305) which senses the operation of the unit key button. The PCB is made of polymer materials. The communications chip is an organic semiconductor based on OTFT(Organic Thin Film Transistor) technique.
