“…However, it suffers from drift and hysteresis. As one of the most conductive materials (only 10 −6 Ω•m), graphene is a suitable material for resistors [ 92 , 93 , 94 , 95 , 96 ]. Kireev et al developed a wearable continuous blood pressure (BP) monitoring platform by using graphene electronic tattoos as human bioelectronic interfaces ( Figure 2 A).…”

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.

“…Nanomaterials have been adopted in the fabrication of various sensors due to their unique properties, including zero-dimensional (0D) nanomaterials (e.g., quantum dots, metal nanoparticles), one-dimensional (1D) nanomaterials (e.g., nanotubes, nanowires), two-dimensional (2D) nanomaterials (e.g., graphene, MXenes), , and various nanocomposites (e.g., nanostructured polymers). − Despite the fact that nanomaterials have made considerable achievements in sensor research, the use of a single nanomaterial can lead to conflicting properties such as sensitivity and linearity. In order to solve this problem and strive for high sensitivity, flexibility, linearity, and stability of the sensors, various methods using mixed-dimensional nanocomposites have been put forward. , In addition, using mixed-dimensional nanocomposites has the advantage of adjustable surface morphological features and has enhanced absorption performance significantly . For mixed-dimensional nanocomposites, the properties, namely, the thermal conductivity, photoconductivity, electron transport, and optical absorption, are expected to be different compared to their single nanostructure counterparts; however, simultaneously integrating the intriguing functions of these counterparts into one material is still a critical unresolved challenge in this field.…”

The implementation of tactile functions in array sensors has created an urgent need for high-performance force sensors with both high linearity and sensitivity so as to ensure the uniformity and accuracy of acquisition of multiple sensing units in the array sensors. In addition, it still remains challenging to fabricate exquisite geometric constructions for integrating highly sensitive materials, extraordinary sensitivity, high stretchability, wide sensing range, and flexibility into a single type of pressure/strain sensor. Herein, a sensitive flexible sensor was fabricated that was composed of mixed-dimensional MXene-based nanocomposites as piezoresistive layers and Ecoflex layers as the encapsulation. The resultant sensors with MXene (Ti3C2T x )-ANF (aramid nanofiber)-BP (black phosphorus)-gold (Au) nanocomposites exhibited excellent electrical conductivity, ultrahigh press sensitivity of 0.4986 kPa–1 (0–1 kPa), reliable linearity (R 2 = 0.998), rapid response time of 12 ms, excellent durability over 4000 cycles, and ultrahigh tensile sensitivity of 9188.583. An 8 × 8 pixel electronic skin was fabricated by the as-prepared mixed-dimensional MXene-based sensors and tested in the identification of sliding movements and surface shape, and the good performance shows great potential applications in the fields of wearable devices, human–machine interaction, and robotics.
