“…Triboelectric whisker sensors utilize the triboelectric effect and electrostatic induction to convert the minute mechanical energy generated by whisker strain into electrical signals, facilitating the analysis of strain information in whiskers. In comparison to piezoelectric sensors, triboelectric sensors possess the advantages of self-driving capabilities, higher output voltage, and lower cost, rendering them more advantageous in the development of sensing systems [104][105][106]. Figure 7A illustrates the structural composition of a triboelectric whisker sensor based on a membrane-structured triboelectric nanogenerator (TENG) [107].…”

Perception plays a pivotal role in both biological and technological interactions with the environment. Recent advancements in whisker sensors, drawing inspiration from nature’s tactile systems, have ushered in a new era of versatile and highly sensitive sensing technology. Whisker sensors, which mimic the tactile hairs of mammals, offer both high sensitivity and multifunctionality. They excel in capturing fine-grained environmental data, detecting various stimuli with precision, and finding applications in diverse domains. This review explores the integration of whisker sensors in potential marine applications. Categorized into six types, these sensors are invaluable for tasks such as marine structure monitoring, measurement instruments, tactile perception in marine robots, and non-contact sensing in the marine environment. Challenges and potential solutions are examined, along with the prospects of whisker sensors in the field of marine science and engineering. In an era that demands adaptable sensing solutions, whisker sensors emerge as pivotal components, enabling machines and devices to perceive and respond to external stimuli with heightened sensitivity and versatility. Their application in the marine domain holds substantial promise, propelling advancements in the realms of marine science and engineering.

“…With the rapid rise in wearable electronic devices, flexible sensors are growing by leaps and bounds and are showing substantial applications in various fields, such as human motion monitoring, − artificial intelligence robotics, − and human–computer interaction. − Crack-structured strain sensors with conductive materials coated on a flexible substrate have become a widely used strategy ,, with advantages such as easy fabrication and short response time. However, it is still a challenge to combine high sensitivity and high tensile range due to the resistance change of crack-based sensors based on the breakage and reversion of the conductive network. , High sensitivity requires the sensor to undergo violent fracture or recovery of the conductive network at a weak stretch, which makes it impossible to maintain the conductive network at large strains .…”

With the rise of the concept of "Internet of Everything", the development of wearable sensing devices is growing rapidly. Among them, crack-based strain sensors have received much attention due to their high sensitivity. However, the application of crack-based strain sensors has been limited by the relatively narrow sensing range. Here, a sandwich structure of a CNT/MXene/CNT sensing layer was realized on the flexible thermoplastic polyurethane substrate prepared by electrospinning, followed by layer-by-layer vacuum filtration. The two stable carbon nanotube (CNT) layers broaden the sensing range, and the strain sensor exhibits excellent sensing range (390%) and stability (3000 tensile tests). The strain sensor also shows excellent sensitivity (GF = 2159.5), low detection limit (0.05%), and fast response time (∼50 ms). The sensor is responsive to different movements when being applied to human motion detection, and the smart wearable device based on the strain sensor shows excellent performance in gesture language recognition. In addition, the antibacterial property of the conductive material inherently facilitates the wider application of the strain sensors.

In this study, poly(2-ethylhexyl acrylate) (PEHA) homopolymer and its copolymer combined with acrylic acid P(EHA- co -AA) were employed as interfaces in two separate Schottky structures. First, both interfaces were grown by initiated chemical vapor deposition (iCVD), which provides much better deposition control and homogeneous coating compared to solution-phase methods. In addition to this advantageous method, the effects of two different polymers, one of which is better able to adhere to the crystal surface on which it is formed than the other, on the optoelectronic properties have been studied. Then, their current–voltage ( I – V ) and capacitance/conductance–voltage ( C /( G /ω)– V ) characteristics were investigated both in the dark and under illumination. The basic electrical parameters and the illumination-induced profile of the surface state ( N ss ) were probed by I – V and C – V measurements for two samples. A decrease in the barrier height (BH) and, consequently, a significant increase in the photocurrent were observed under illumination. Striking changes in series resistance ( R s ) values are also highlighted. The photocapacitance and conductance characteristics indicated that the structures could be considered not only as photodiodes but also as photocapacitors. Moreover, the voltage-dependent changes of some photodetector parameters, such as responsivity ( R ), sensitivity ( S ), and specific detectivity ( D *), along with the transient photocurrent characteristics, are discussed for both structures. Therefore, we can say that the strong changes in these parameters, which figure the merit of photodiode and photodetector applications, depending on the voltage and under illumination, prove that it is a study carried out in accordance with the purpose and so they can be used in electronic and optoelectronic applications.
