“…The special geometry of graphene can provide more contact points when pressure is applied, and the transition from 2D to 3D can improve the performance detection and enhance the sensor performance. For example, star‐shaped graphene, a 3D conductive filler with different surface morphologies, [ 73 ] has excellent electrical conductivity, strong mechanical strength, and light weight. Low‐voltage sensitivity can be improved in the dielectric layer by exploiting the quantum tunneling effect and stress concentration effect between the sharp structures of nanoparticles.…”

As one of the important physiological signals of the human body, changes in respiration can provide an important reference for human health and is an early warning signal for some chronic respiratory diseases on heart or lung diseases. Usually, doctors combine such changes with electrocardiograph (ECG), electroencephalograph (EEG), electromyography (EMG), and electrooculogram (EOG) results of the patient to make a comprehensive analysis and judgment of the condition. Traditional respiratory monitoring methods have the limitation that portability and accuracy cannot be balanced; while the wearable respiratory monitoring sensors have come into the public's view due to their excellent performances, such as light weight, fast response, not interfering with the subject's daily movement, and maintaining excellent measurement accuracy, which provide more possibilities for the improvement of the performances of the wearable devices applied in the early stage of chronic diseases.

“…Gao et al developed a flexible pressure sensor using 3D porous MXene/reduced Graphene oxide (MXene/rGO) mixed foam as piezoresistive sensing material through efficient hydrothermal synthesis and new reduction method of flash transient radiation. [87] Compared with traditional reduction methods, this instantaneous reduction process can effectively keep MXene nano sheets in tightly interconnected rGO sheets, so that the proposed MXene/rGO hybrid foam has strong mechanical elasticity and high conductivity. Due to the three-dimensional porous framework structure of MXene/rGO mixed foam, the proposed pressure sensor has good sensing performance.…”

“…The 3D structure of foam itself can be used to dip or coat MXene on it to obtain 3D MXene flexible pressure sensor. [82][83][84][85][86][87][88] Zhu et al prepared a flexible pressure sensor by directly freezedrying Ti 3 C 2 T x MXene/bamboo cellulose fiber slurry and then encapsulating it with PDMS elastomer. [82] The manufacturing strategy is simple and scalable.…”

In the past decade, with the rapid development of wearable electronics, medical health monitoring, internet of things and flexible intelligent robots, flexible pressure sensors have received unprecedented attention. As a very important kind of electronic components for information transmission and collection, flexible pressure sensor has gained a wide application prospect in the fields of aerospace, biomedical and health monitoring, electronic skin and human‐machine interface. In recent years, MXene has attracted extensive attention because of its unique two‐dimensional layered structure, high conductivity, rich surface terminal groups and hydrophilicity, which has brought a new breakthrough for flexible sensing. Thus, it has become a revolutionary pressure sensitive material with great potential. In this work, the recent advances of MXene‐based flexible pressure sensors is reviewed from the aspects of sensing type, sensing mechanism, material selection, structural design, preparation strategy and sensing application. The methods and strategies to improve the performance of MXene‐based flexible pressure sensors are analyzed in details. Finally, the opportunities and challenges faced by MXene‐based flexible pressure sensors are discussed. This review will bring the research and development of MXene‐based flexible sensors to a new high level, promoting the wider research exploitation and practical application of MXene materials in flexible pressure sensors.This article is protected by copyright.
