Bioinspired fabrics with single fiber as ultra-sensitive acoustic sensor

Sensing audible signals with wearable fabrics remains a challenge due to the hierarchical, interface-induced sound dissipation and low transduction efficiency of fiber components. Recent exciting progress published in Nature employs single piezoelectric fibers woven into high-modulus fabrics and demonstrates an ultra-sensitive microphone, which may pave a promising way for wearable, audio-sensing fabrics.
