Conductive Nanomaterials with Different Dimensions for Flexible Piezoresistive Sensors: From Selectivity to Applications

Flexible piezoresistive devices have boomed with the rapid development of industries such as "Big Data" and "Internet of Things" in recent years. Intense studies have proved that conductive nanomaterials can serve as excellent conductive layers for constructing high-performance flexible piezoresistive sensors. In this paper, the most advanced developments in flexible piezoresistive sensors prepared by multi-dimension conductive nanomaterials are systematically summarized, in which 0D, 1D, and 2D, 0D/1D, 0D/2D, 1D/2D and multi-component hybrid nanomaterials are introduced in detail. In addition, the limitations and perspectives for further development of flexible piezoresistive sensors are also discussed. It is hoped that this review can inspire more exciting work on conductive nanomaterial-based flexible piezoresistive sensors, thereby promoting their practical applications.
