The smart textile research community is advancing rapidly with the aim of changing the way we wear clothes in the near future. An eardrum-inspired acoustic textile was recently developed that can function as a sensitive audible microphone. The acoustic textile is woven from yarns with a high Young’s modulus and thermal drawing composite piezoelectric fibers that can concentrate mechanical stress in the piezoelectric composite layer during the heat drawing process, endowing the fiber with high sensitivity. The acoustic textile can convert even very slight 10⁻⁷ atmospheric pressure waves at audible frequencies into mechanical vibrations with nanometer amplitudes, which further induce the electrical signals through the fibers to detect the direction of sound pulses, broadcast human speech, and capture heartbeats, making it suitable as a wearable platform for long-term biomonitoring.

智能纺织品研究社区正在迅速发展，目的是在不久的将来改变我们穿衣服的方式。最近开发了一种受耳膜启发的声学纺织品，可以用作灵敏的可听麦克风。声学纺织品由具有高杨氏模量的纱线和热拉伸复合压电纤维编织而成，在热拉伸过程中可以将机械应力集中在压电复合层中，赋予纤维高灵敏度。声学纺织品甚至可以转换非常轻微的 10 ^-7可听频率的大气压力波转化为纳米振幅的机械振动，进一步通过纤维诱导电信号以检测声音脉冲的方向、广播人类语音和捕捉心跳，使其适合作为长期生物监测的可穿戴平台.
