VIBRATION SENSING SENSER USING PIEZOELECTRIC RUBBER COMPOSITION AND THE MANUFACTURE METHOD

摘要

The present invention relates to a piezoelectric rubber composition used in a vibration sensing sensor, and a manufacturing method thereof wherein the piezoelectric rubber composition comprises: 5-20 parts by weight of conducting metal materials; 0.1-0.5 parts by weight of metal salt-based phthalocyanine; 0.1-0.5 parts by weight of conducting polymers; 4-10 parts by weight of ethyl silicate; 1-2 parts by weight of polypropylene glycol; 0.5-1 parts by weight of a coupling agent; 70-85 parts by weight of silicon resins with respect to 100 parts by weight of rubbers. Therefore, in the present invention, the piezoelectric rubber composition uses metal salt-based phthalocyanine and conducting polymers and is accordingly used in machines which sense vibration.
