Infrasonic wave is the usually sound wave caused by vibrating body at frequency below 20Hz, which is commonly found in a variety of industry, transportation, nature and living environment. This paper designs a high precision infrasonic sound sensor based on PVDF, which is a new piezoelectric material of macromolecule with piezoelectric property. The research results proved that when a given frequency values between 3Hz to 30Hz, the proposed sensor has good performance and high precision, which could meet the design requirements, and has a certain practical value.
