Wearable and visual pressure sensors based on Zn₂GeO₄@polypyrrole nanowire aerogels

Abstract

A high-performance and tailorable pressure sensor based on the Zn₂GeO₄@PPy nanowire aerogel for applications in visual and wearable fields has been developed and show high sensitivity of the pressure sensor (0.38 kPa⁻¹at pressure regions less than 1.5 kPa). We also combined the aerogels with Light Emitting Diode which make a visible sensor come true.
