摘要

Cotton fiber-based functional aerogel is prepared and shows excellent elasticity and steady resistance value evolution at cryogenic temperature (77 K)

enabling great potential for being used as strain sensor in low temperature environment.

Abstract

With the development of electronic technologies

piezoresistive sensors have attracted increasing attention. Among them

aerogels with high elasticity

as a type of three-dimensional porous material

are widely used in the field of piezoresistive sensors. Nowadays

with the extension of science and technology areas

fields involving low-temperature environments have emerged

which has led to an increasing demand for piezoresistive sensors that can serve at cryogenic temperatures. However

most studies on aerogels have only focused on their sensing performance at room temperature

and there is a lack of research on aerogel sensors that can work at low temperatures. In this work

piezoresistive sensors based on cotton fibers were proposed for applications at 77 K. As one of the most important natural polymers

cotton fibers have the ability to maintain elasticity at very low temperatures. Cotton fiber-based aerogels with high elasticity and cyclic stability were obtained by controlling the freeze-casting parameters and size distribution of cotton fibers

and they showed excellent pressure sensing properties

including a wide sensing range and remarkable long-term stability. This study bridges the gap in cryogenic sensing materials and provides insights into microstructure-property relationships

advancing applications in aerospace and cryogenic engineering.
