Abstract

Recent developments in piezoresistive flexible pressure sensors have generated a lot of interest because of the possible uses across numerous industries. With a focus on improving sensor performance, this paper covers current developments in the area of piezoresistive flexible pressure sensors. Over the years, there has been a growing interest in improving the capabilities of these sensors, leading researchers to explore various avenues for enhancement. The review highlights two primary areas of research: the optimization of active materials and the enhancement of sensor structures. These areas are actively being investigated to achieve superior sensor performance and overall functionality. In addition to utilizing high-quality materials, optimizing the sensor’s structure is crucial for achieving improved sensitivity, accuracy, and stability. The review also explores the wide range of applications where pressure sensors have made significant contributions, including human motion monitoring, healthcare, and other domains. Flexible and highly sensitive pressure sensors have the potential to revolutionize several sectors and open up new opportunities.
