摘要

This study described a miniaturized, flexible, and highly sensitive sound locating and recognition sensor. It is achieved by using a polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) film to enhance piezoelectric performance by in-situ polarization. The high piezoelectric coefficient enhances the acoustic-electric conversion capability of the sensor. By using our polarizing system, the PVDF-TrFE film can be polarized in 5 minutes at room temperature. Compared with the traditional polarization method, the in-situ polarization system has the advantages of higher piezoelectric coefficient, more uniform d33 distribution and higher production efficiency. The sound locating and recognition sensor can generate a voltage response by inducing a sound signal to locate the sound source and analyse the voltage signal to obtain the frequency of the sound source. These can be used to accurately identify complex sound signals with different frequencies and intensities. In addition, the sensor is self-powered. All the above features make it have great potential in various applications, such as biometrics, environmental protection and artificial intelligence.
