The piezoresistive effect has been a dominant mechanical sensing principle that has been widely employed in a range of sensing applications. This transducing concept still receives great attention because of the huge demand for developing small, low-cost, and high-performance sensing devices. Many researchers have extensively explored new methods to enhance the piezoresistive effect and to make sensors more and more sensitive. Many interesting phenomena and mechanisms to enhance the sensitivity have been discovered. Numerous review papers on the piezoresistive effect have been published; however, there is no comprehensive review article that thoroughly analyses methods and approaches to enhance the piezoresistive effect. This paper comprehensively reviews and presents all the advanced enhancement methods ranging from the quantum physical effect and new materials to nanoscopic and macroscopic structures, and from conventional rigid to flexible, stretchable and wearable applications. In addition, the paper summarises results recently achieved on applying the above-mentioned innovative sensing enhancement techniques in making extremely sensitive piezoresistive transducers.

超灵敏压阻传感器的进展：从传统应用到柔性和可拉伸应用

压阻效应一直是主要的机械传感原理，已广泛应用于一系列传感应用中。由于对开发小型、低成本和高性能传感设备的巨大需求，这种传感概念仍然受到广泛关注。许多研究人员已经广泛探索了增强压阻效应并使传感器越来越敏感的新方法。已经发现了许多提高灵敏度的有趣现象和机制。发表了多篇关于压阻效应的评论论文；然而，没有全面的评论文章彻底分析增强压阻效应的方法和途径。本文全面回顾并介绍了从量子物理效应和新材料到纳米级和宏观结构，以及从传统刚性到柔性、可拉伸和可穿戴应用的所有先进增强方法。此外，本文总结了最近在应用上述创新传感增强技术制造极其敏感的压阻式传感器方面取得的成果。
