Abstract

Objective: This review explores the potential of graphene, a two-dimensional carbon allotrope, in revolutionizing pressure sensors. Graphene's exceptional electrical and mechanical properties enable significant advancements in sensitivity, dynamic range, response time, and flexibility, addressing limitations in traditional sensor technologies. Methods: The study examines the fundamental mechanisms of graphene-based pressure sensors, including piezoresistive, capacitive, and field-effect transistor (FET) mechanisms. A comparative analysis of conventional materials such as piezoelectric, metallic, silicon, and polymer-based materials is conducted to highlight their strengths and limitations. The integration of nanomaterials, particularly graphene, into sensor designs is reviewed, emphasizing their contributions to enhanced sensor performance. Results: Graphene-based sensors demonstrate superior sensitivity and miniaturization capabilities due to their high surface-to-volume ratio, tunable electrical conductivities, and mechanical resilience. Emerging applications in healthcare, electronics, and robotics validate the transformative impact of graphene on sensor technologies. Novelty: This review underscores the unique advantages of graphene over traditional materials, emphasizing its potential to address challenges related to sensitivity, response time, and durability in extreme conditions. Future research directions are proposed to overcome existing limitations and expand the scope of graphene-based sensors across diverse industries.

Abstract

Nanotechnology can revolutionize the sensor industry by introducing specific nanomaterials to work as sensing elements. Graphene, a two-dimensional carbon allotrope with exceptional electrical and mechanical properties, has emerged as a promising material for developing high-performance pressure sensors. Graphene-based pressure sensors offer significant advantages over traditional sensors, including high sensitivity, wide dynamic range, fast response time, and flexibility. This paper aims to deliver a review on the fundamental mechanisms underlying graphene-based pressure sensors, which includes piezoresistive, capacitive, and field-effect transistor (FET). Recent advancements in graphene-based pressure sensors have opened up new possibilities in various fields, including healthcare, electronics, and robotics. Here, we will highlight these emerging applications and explore the potential future developments of this technology.
