In the past decades, the rapid development of the Internet of Things (IoT) technology and artificial intelligence (AI) has driven the research boom of physical sensors. Material selection, structure design, and performance research for physical sensors have attracted extensive attention from worldwide researchers in the field of advanced manufacturing. Significant technological progress has been made in the area of physical sensors for applications in various fields such as electronic skin, biomedicine, and tissue engineering. There are many methods (e.g., electrospinning, screen printing, or rotary coating) to prepare physical sensors. Among them, nanofibers or nanofiber membranes prepared by electrospinning have the advantages of a nanosize effect, high specific surface area, and high porosity over other reported materials used for physical sensors. In this review, the working principles of various physical sensors including pressure sensors, strain sensors, temperature sensors, and humidity sensors are first introduced; recent research progress of electrospun nanofiber-based physical sensors is then summarized. Finally, future research trends and associated challenges of large-scale adoption of electrospun physical sensors are proposed.

MXene is typically exfoliated by selective etching the A layer of MAX phase. [1] One example of MXene, Ti 3 C 2 F x , satisfies the stoichiometric ratio of n + 1/n, in which M, X, and T stand for transition metals, carbon or nitrogen, terminal groups at surfaces, respectively. The MXene has exhibited extraordinary electrical, [2][3][4] optical, [5] mechanical, [6][7][8] and electrochemical properties [9] since its first discovery, [10] which has become an emerging material for sensing, [11,12] communication, [13,14] energy, [15,16] environmental, [17] and healthcare applications. [18][19][20] There are many reviews existing for electrochemical energy storage, including supercapacitors, lithium ion batteries, [21][22][23] sodium ion batteries, zinc ion batteries, [24][25][26] lithium-sulfur batteries, and energy conversions, [27][28][29] includingThe Internet of Things era has promoted enormous research on sensors, communications, data fusion, and actuators. Among them, sensors are a prerequisite for acquiring the environmental information for delivering to an artificial data center to make decisions. The MXene-based sensors have aroused tremendous interest because of their extraordinary performances. In this review, the electrical, electronic, and optical properties of MXenes are first introduced. Next, the MXene-based sensors are discussed according to the sensing mechanisms such as electronic, electrochemical, and optical methods. Initially, biosensors are introduced based on chemiresistors and field-effect transistors. Besides, the wearable pressure sensor is demonstrated with piezoresistive devices. Third, the electrochemical methods include amperometry and electrochemiluminescence as examples. In addition, the optical approaches refer to surface plasmonic resonance and fluorescence resonance energy transfer. Moreover, the prospects are delivered of multimodal data fusion toward complicated human-like senses. Eventually, future opportunities for MXene research are conveyed in the new material discovery, structure design, and proof-of-concept devices.

“…Compressible and wearable pressure sensory devices have witnessed significant advances over the past 10 years owing to their numerous applications including human motion tracking, personal healthcare monitoring, soft robotics, artificial intelligence, and so forth. − Piezoresistive sensors are regarded as promising candidates for wearable pressure-sensing electronics due to their straightforward design, cost-effectiveness, simplicity of operation, and high compression and deformation sensitivity. − Pressure-sensing devices can convert pressure into variation in resistance, thus realizing the real-time detection of various motions and deformations via the change in current. Recently, flexible polymer and elastomeric films loaded with conducting particles including graphene, , graphite particles, carbon nanotubes (CNTs), − and conducting polymers (such as PEDOT:PSS, polyaniline, and so forth) − have been used as a sensing platform for flexible piezoresistive sensors. − For example, Liu and co-workers fabricated bacteria cellulose (BC) intercalated MXene films using plain paper as a flexible substrate by vacuum filtration.…”

Electronic devices with tactile and pressure-sensing capabilities are becoming increasingly popular in the automatic industry, human motion/health monitoring, and artificial intelligence applications. Inspired by the natural nanotopography of the cicada wing, we propose here a straightforward strategy to fabricate a highly sensitive tactile sensor through nanotexturing of erected polyaniline (PANI) nanoneedles on a conductive and elastic three-dimensional (3D) carbon skeleton. The robust and compressible carbon networks offer a resilient and conducting matrix to catering complex scenarios; the biomimetic PANI nanoneedles firmly and densely anchored on a 3D carbon skeleton provide intimate electrical contact under subtle deformation. As a result, a piezoresistive tactile sensor with ultrahigh sensitivity (33.52 kPa–1), fast response/recovery abilities (97/111 ms), and reproducible sensing performance (2500 cycles) is developed, which is capable of distinguishing motions in a wide pressure range from 4.66 Pa to 60 kPa, detecting spatial pressure distribution, and monitoring various gestures in a wireless manner. These excellent performances demonstrate the great potential of nature-inspired tactile sensors for practical human motion monitoring and artificial intelligence applications.
