Field emission effect in triboelectric nanogenerators

Nature Communications
Abstract Triboelectric nanogenerators (TENGs) have garnered increasing attention due to their exceptional ability to convert mechanical energy into electricity. Previous understanding is that the electric performance of TENGs is primarily restricted by contact electrification, air breakdown, and dielectric breakdown effects.

Miniature Nanomesh Mechano‐Acoustic Sensor with Wide Linear Dynamic Range, Broad Bandwidth, and Flat Frequency Response

Advanced Functional Materials, EarlyView.
A miniaturized mechano‐acoustic sensor is developed using an electrospun PVDF nanomesh as the diaphragm in a capacitive sensor structure. Unlike conventional nanomesh‐based sensors, it achieves high linear sensitivity, a broad and flat frequency response, and a compact form factor.
