“…In comparison with PVDF, traditional sensors that are based on lead zirconate titanate (PZT) are generally considered be devoid of softness and are toxic . Nevertheless, recent researches suggest PZT mixed with and wrapped within polymers provides both enhanced stretchability and relaxed toxicity. , Besides, functional units of the sensor could be integrated with the flexible/elastic piezoelectric film to achieve a combination of high charge density, mechanical toughness as well as sensitive response toward multiple stimuli, which are essential for sensor to mimic our skin. , As a result, PZT-based stretchable sensors could also permit large deformation and fulfill the fundamental requirement for conformal integration with artificial electronic-skins and various wearable devices.…”

Smart sensors are expected to be sustainable, stretchable, biocomfortable, and tactile over time, either in terms of mechanical performance, reconfigurability, or energy supply. Here, a biocompatible piezoelectric electronic skin (PENG) is demonstrated on the base of PZT-SEBS (lead zirconate titanate and styrene ethylene butylene styrene) composite elastomer. The highly elastic (with an elasticity of about 950%) PENG can not only harvest mechanical energy from ambient environment, but also show low toxicity and excellent sensing performance toward multiple external stimuli. The synchronous and independent sensing performance toward motion capture, temperature, voice identification, and especially the dual-dimensional force perception promotes its wide application in physiological, sound restoration, and other intelligent systems.

“…These results reveal that the Ag shell can combine BCZT to form strong interfacial polarization and the higher polarization is indicative about favorable piezoelectric performance of sample. [ 49 ] Besides, the dielectric constants (ε r ) of samples were measured at 1000 Hz with various concentrations of 3D‐BCZT@Ag. As shown in Figure 6d, with the concentration of 3D‐BCZT@Ag increasing, the ε r (red line) of composites increases gradually, which attributes to the higher dielectric constant of BCZT than that of silicone rubber matrix.…”

that people pursued are independent, sustainable, and maintenance free for power supply unit. However, these devices are still mainly powered by traditional batteries. The problems of battery power, such as replacement and waste disposal of battery, not only cause a lot of inconvenience to maintain devices, but also have a negative impact on environmental protection, which runs counter to people's design ideal. Therefore, the energy harvesting technique for self-powered device provides an effective pathway that could replace traditional battery power in IOT. [5][6][7][8][9] The piezoelectric nanogenerator (PENG) can realize the conversion of mechanical energy to electrical energy based on piezoelectric effect, which can harvest mechanical energy and produce electrical output under the mechanical stimulation, such as compression, tension, and twist. Compared with triboelectric generator, PENG has the advantages of little influence by environmental factors, long service life, and stable output performance, which has been considered as promising in the approach of IOT and self-powered sensors network. [10][11][12][13][14] However, the output performance of PENG is generally lower than as expected, and further research is needed to improve the performance of PENG.In general, the flexible PENG based on inorganic/organic composites is usually composed of piezoelectric ceramic fillers and polymer materials due to the composites can combine the favorable piezoelectric response of ceramics and excellent flexibility of polymer. For improving the performance of PENG, the most direct and effective way is to select doped ceramics with good piezoelectric performance. Up to present, there are various types of piezoelectric ceramic systems, such as Pb(Zr 1-x Ti x )O 3 (PZT), (K 0.5 Na 0.5 )NbO 3 (KNN), (Bi 0.5 Na 0.5 )TiO 3 (BNT), and BaTiO 3 (BT). [15][16][17][18][19][20] Among them, the Pb based piezoelectric ceramics have been widely applied in industry for decades, which attributes to their excellent and stable piezoelectric properties. However, with the requirement for environmentfriendly, the exploration of lead-free piezo-ceramics as inorganic fillers in flexible PENG has been in progress. The low-cost BT With the popularity of portable and miniaturized electronic devices in people's live, flexible piezoelectric nanogenerators (PENG) have become a research hotspot for harvesting energy from the living environment to power smallscale electronic equipment and systems because of its stability. For further enhancing output performance of PENG, chemical modification and structural design for piezoelectric fillers are effective ways. Thus, the 3D porous heterostructure fillers of BCZT@Ag are prepared by freeze-drying method and subsequent chemical seeding reduction. The silicone rubber as matrix is filled into the micro-voids of fillers to prepare specialized composite. The charge transport mechanism and stress transfer efficiency in PENG can be effectively improved through specialized design which is proven by experimental res...

“…The most widely investigated FPEH devices and related applications are based on 0-3 type piezoelectric/polymer composites owing to the simple and cost-effective device preparation processes. [108][109][110][111][112][113][114][115][116][117][118][119][120][121] Ideally, in a 0-3 type composite, ferroelectric particle to particle interactions in three directions are negligible. On the other hand, the polymer matrix has connectivity and hence interactions in all three directions.…”
