ELECTRONIC DEVICE WHICH SENSES CONTACT AND CONTACT SENSING METHOD THEREOF WHICH USES AN OPTICAL FIBER

摘要

PURPOSE: An electronic device and contact sensing method thereof are provided to accurately sense the contact of an object material by using a simple structure which includes an optical fiber.;CONSTITUTION: A contact unit(102) outputs a sensing signal about the contact of an object material. A controller(114) senses the contact of the object material by using the sensing signal. The contact unit includes a light emitting unit, a light connector, and light detector through a first optical fiber. The light connector splits the light which is transmitted through the first optical fiber. The light detector outputs a sensing signal about contact of the object material.;COPYRIGHT KIPO 2011
