Flexible Piezolectric Acoustic Sensor
Voice recognition (VR) is the most straight forward and intuitive user-interface for the future IoT era. FRONICS' smart acoustic sensor is based on unique flexible piezoelectric materials and device structure , which mimics a human cochlear organ.
We have developed multi-channel acoustic sensor capable of highly sensitive recognition of human voice frequency band, 300 ~ 3kHz. In particular, our smart acoustic sensor has higher sensitivity compare to the conventional microphone, that enables voice recognition from a distance. In addition, multi-channel acoustic sensor can be used in high accuracy speaker recognition based on the machine-leaning algorithm, which can be applicable in the field of low power VR, AI, smart home applicances, connected car, voice security, and etc.
FRONICS Inc. holds many domestic/international patents regarding the acoustic sensor and is the looking for global partnerships for commercialization.
