Revolutionizing sensing technologies: A comprehensive review of flexible acceleration sensors

Abstract

Flexible sensing technologies are pivotal for achieving multidimensional spatial freedom in sensing capabilities. Within this domain, flexible acceleration sensors stand out as innovative devices capable of accurately monitoring acceleration signals, even amidst deformation scenarios such as bending, compression, or stretching. These sensors are increasingly recognized for their transformative potential across various sectors, including health monitoring, industrial machinery, soft robotics, and so on. This review delves into the recent progress in the field of flexible acceleration sensors, examining their operational mechanisms, the materials used for the sensing layers, and their performance characteristics based on different operational principles. Moreover, we explore the diverse applications of these sensors in areas such as wearable devices, infrastructure surveillance, and automotive safety, providing a comprehensive overview of their current uses. Additionally, we assess the advantages and limitations of flexible acceleration sensors and propose potential directions for their advancement. Through this review, we aim to highlight the significant role that flexible acceleration sensors play in the ongoing evolution of sensing technologies, underscoring their importance in a wide array of applications.
