“…[199][200][201] Depending on the nature of the materials, piezoelectric materials can be roughly divided into four categories: inorganic, organic, composite, and natural piezoelectric materials. Various piezoelectric materials have been developed for PENGs over the past decades, such as zinc oxide (ZnO), [202][203][204][205][206][207][208][209] aluminum nitride (AlN), [210][211][212] barium titanate (BaTiO 3 ), [213][214][215] lead zirconate titanate (PZT), [216][217][218] Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT), [219][220][221] molybdenum sulfide (MoS 2 ), [222][223][224][225][226][227][228] poly(vinylidene fluoride) (PVDF), [229][230][231][232][233] poly(L-lactic acid) (PLLA), [234][235][236][237] bacterial viruses, [238][239][240][241] engineered eggshell, 242,243 engineered f...…”

Sweeping developments in microelectromechanical systems and low power electronics have pushed the need for piezoelectric energy harvesters (PEHs).Increasing environmental and biocompatibility issues have drawn interest in lead-free piezoelectric materials. In this paper, cantilever-type PEHs at centimeter scale have been proposed to harvest the energies of low-frequency vibrations caused by a human's movements. The proposed PEHs are made of a

“…For instance, in the aerospace field, aircraft and sandwich shield are sandwich structures (Arunkumar et al 2017;Cherniaev and Telichev 2017). And for high performance lithium ion batteries and energy harvesters, sandwich porous structure plays a major advantage (Qu et al 2018;Tummala et al 2017;Zeng et al 2017). Similarly, in the field of building materials, the sandwich structures are usually applied to realize various functions (Bach et al 2017;Chróścielewski et al 2017;Hopkins et al 2017;Pascual et al 2017;Tabatabaiefar et al 2017).…”

High-strength and lightweight are two of the most important parameters for composites in the construction field. Here, we developed a novel foam concrete structure with sandwich porous structure by using in-situ polymerized polyacrylamide and ultra-stable foam, which can obtain higher mechanical strength in comparison to the normal porous concrete with the same density. The ratio of stiffness to weight was maximized to achieve the optimal sandwich porous structure size. The SEM images showed that the interface bond between the foam concrete and the polymer modified cement paste was tight and robust. The flexural strength of the novel structure was 65.6% higher than that of the foamed concrete at the same density. The series model was established to calculate the composite thermal conductivity of the novel foam concrete structure, indicating that the heat insulation was slightly improved compared with the normal foam concrete. Moreover, water resistance displayed a slight increase by constructing this sandwich porous structure. Hopefully, the novel composite with sandwich porous structure can put a new way for designing the lightweight and high strength insulation thermal structure.
