“…Therefore, this is a novel approach for energy harvesting in human-machine interfaces. To solve the wireless communication problem of human-computer interaction, Su et al [121] investigated a new type of self-powered visualized flexible pressure sensor (SP-VFPS) based on a micro-compression-porous structure and single-electrode friction nanogenerator matrix-integrated self-powered sensor system (Figure 6e). The system can respond to the tribe-electroluminescence (TIEL) generated by the vertical pressure in real-time through experiments.…”

With the rapid progress of artificial intelligence, humans are moving toward the era of the intelligent connection of all things. Therefore, the demand for sensors is drastically increasing with developing intelligent social applications. Traditional sensors must be triggered by an external power source and the energy consumption is high for equipment that is widely distributed and working intermittently, which is not conducive to developing sustainable green and healthy applications. However, self-powered sensors based on triboelectric nanogenerators (TENG) can autonomously harvest energy from the surrounding environment and convert this energy into electrical energy for storage. Sensors can also be self-powered without an external power supply, which is vital for smart cities, smart homes, smart transportation, environmental monitoring, wearable devices, and bio-medicine. This review mainly summarizes the working mechanism of TENG and the research progress of self-powered sensors based on TENG about the Internet of Things (IoT), robotics, human–computer interaction, and intelligent medical fields in recent years.

“…To detect normal force efficiently, vertically oriented polyvinylidene fluoride (PVDF) fibers have been fabricated to obtain new types of pressure sensors [ 118 ]. Furthermore, with other nanowire-shaped piezoelectric sensors from highly aligned polyvinylidene fluoride-trifluoroethylene P(VDF–TrFE) with excellent sensitivity (458.2 mVN −1 ), basic life functions such as breath or pulse can be monitored [ 119 ].…”

Smart piezoelectric materials are of great interest due to their unique properties. Piezoelectric materials can transform mechanical energy into electricity and vice versa. There are mono and polycrystals (piezoceramics), polymers, and composites in the group of piezoelectric materials. Recent years show progress in the applications of piezoelectric materials in biomedical devices due to their biocompatibility and biodegradability. Medical devices such as actuators and sensors, energy harvesting devices, and active scaffolds for neural tissue engineering are continually explored. Sensors and actuators from piezoelectric materials can convert flow rate, pressure, etc., to generate energy or consume it. This paper consists of using smart materials to design medical devices and provide a greater understanding of the piezoelectric effect in the medical industry presently. A greater understanding of piezoelectricity is necessary regarding the future development and industry challenges.

“…[ 20 , 21 , 22 ] Recently, in order to improve the overall performance of e‐skins, they have been endowed with special functions, such as electroluminescence, self‐healing, shape memory effect, fireproofing, waterproofing, and heat transfer. [ 14 , 23 , 24 , 25 , 26 ] Despite the continuous improvement and optimization of the abovementioned multiple functions, e‐skins that can truly imitate human skin and its multiple functions to achieve optimal integration are extremely rare; although this forms the basis for e‐skin to be truly intelligent with widespread applications. [ 7 , 27 , 28 ] Most e‐skins can detect only one type of external stimulus, significantly restricting their practical applications.…”

“…To address this issue, new conductive or luminescent materials have been developed to increase the sensitivity of e‐skin to pressure, temperature, or humidity, with the need for a complicated synthesis process. [ 24 , 30 ] In previous studies, an increased sensitivity was achieved by designing and modifying the structure of the material, such as imitating pyramid or skin‐inspired materials, to obtain a larger contact area under same pressure. [ 31 , 32 , 33 ] However, this method often requires etching or mold inversion, leading to a complicated production process and expensive manufacturing.…”

For the practical applications of wearable electronic skin (e‐skin), the multifunctional, self‐powered, biodegradable, biocompatible, and breathable materials are needed to be assessed and tailored simultaneously. Integration of these features in flexible e‐skin is highly desirable; however, it is challenging to construct an e‐skin to meet the requirements of practical applications. Herein, a bio‐inspired multifunctional e‐skin with a multilayer nanostructure based on spider web and ant tentacle is constructed, which can collect biological energy through a triboelectric nanogenerator for the simultaneous detection of pressure, humidity, and temperature. Owing to the poly(vinyl alcohol)/poly(vinylidene fluoride) nanofibers spider web structure, internal bead‐chain structure, and the collagen aggregate nanofibers based positive friction material, e‐skin exhibits the highest pressure sensitivity (0.48 V kPa−1) and high detection range (0–135 kPa). Synchronously, the nanofibers imitating the antennae of ants provide e‐skin with short response and recovery time (16 and 25 s, respectively) to a wide humidity range (25–85% RH). The e‐skin is demonstrated to exhibit temperature coefficient of resistance (TCR = 0.0075 °C−1) in a range of the surrounding temperature (27–55 °C). Moreover, the natural collagen aggregate and the all‐nanofibers structure ensure the biodegradability, biocompatibility, and breathability of the e‐skin, showing great promise for practicability.
