Acoustic Sensors: Broad Bandwidth, Self‐Powered Acoustic Sensor Created by Dynamic Near‐Field Electrospinning of Suspended, Transparent Piezoelectric Nanofiber Mesh (Small 28/2020)

Most acoustic sensors are resonant systems, thus the associated sensitivity bandwidth is narrow. In article number 2000581, Yan Yan Shery Huang and co-workers fabricate a broad bandwidth acoustic sensor, inspired by the acoustic sensing mechanism of the spider silk, by dynamic near-field electrospinning. Composed of freely suspended piezoelectric nanofibers, the self-powered, transparent acoustic sensor has high sensitivity throughout the majority of the audible sound spectrum at hearing-safe loudness level.
