Yan et al. designed an acoustic fabric, woven with a fiber that is designed from a piezoelectric material that produces an electrical signal when bent or mechanically deformed: (a) the tympanic membrane is a four-layer construct composed of circumferentially and radially oriented high-modulus collagen fibers, which are key for sound conduction; the tympanic membrane motion is ultimately transmitted to the cochlea through the ossicular chain, wherein short cilia fibers convert pressure waves into electrical signals (ionic), which are picked up by the nervous system; (b) in the acoustic fabric, high-modulus Twaron yarns and cotton yarns are oriented at right angles, mimicking the construction of the tympanic membrane; this construction converts faint audible frequency sound pressure waves into low-order mechanical vibration modes; within that same medium, a single strand of piezoelectric elastomeric fiber transducer is woven, leading to a synergistically coupled fabric, where sound transduction is a collective effect; this results in a fabric capable of operating as a sensitive microphone that detects weak sound signals (for example, human speech) as low as 10-7 atm.

Assembly of nanostructured CNF fibers. Upper image: schematic of double flow-focusing channel used for CNF assembly; the CNF suspension is injected in the core flow (light brown color), deionized water (blue color) in the first sheath, and acid at low pH (light green color) in the second sheath flows; arrows show the flow direction; hydrodynamic and electrostatic interactions at different positions along the channel are illustrated schematically on the right. Bottom images: SEM image (left) of the fiber surface, where the dense fibrillar network with well-preserved anisotropic arrangement can be seen; SEM image (right) of the cross section of the fiber, showing the aligned nanofibrils. Scale bars are 3 μm; in insets are 400 nm. Image credit: Mittal et al, doi: 10.1021/acsnano.8b01084.
