“…With the rapid development of advanced materials and nanotechnology, although the microdevices have evolved to a comparatively high level, most of them still need external power supply, usually batteries, which might cause difficulties to recycle or environment pollution. Thus, based on versatile reactions such as pyroelectric, [170,171] piezoelectric, [172,173] and triboelectric effect, [174,175] the self-charge MBs harvesting energy from ambient environment have gained great attentions of researchers and been applied in multiple fields throughout people's life.…”

considered indispensable and stimulate great upsurge in interest on relevant researches. [1-4] Through integrating with multiple functional materials or devices, the miniaturized energy-storage device can power functional systems, such as microactuators, implantable biosensors, and wearable gadgets. [5,6] As far as the performance is concerned, the shift from disposable or nonrechargeable product to a high-energy output device or even complicated system has motivated the improvement of energy storage capability during the past decade. Generally, microsupercapacitor (MSC) possesses the advantages of fast charge/discharge rate and long cycling lifetime, making it possible for some maintenance-free wearable microelectronics and biomedical devices. [7,8] However, the energy storage gap about an order of magnitude still exists in comparison with microbattery (MB), and the insufficient energy supply restricts the widespread applications of MSC in the main power systems. [9] Serving as the primary choice for powering advanced miniaturized devices, MBs ensure sufficient energy density and maintain a stable voltage output. In general, a rechargeable battery consists of cathode, anode, and electrolyte in between, therefore it is the electrode that calls for miniaturization in size ranging from microns to centimeters. The total energy available in a MB generally depends on the active materials loaded on a certain small area. Based on this, some concepts of MB have been proposed, such as ultrathin microelectrode for high volumetric specific energy and somewhat thick microelectrode for high areal specific energy. [10,11] In terms of the dimensional ratio of MB, the thickness of microelectrode gives priority to the transport distance of ions and electrons, thus favoring the improvement in power density when compared with the macro one. [12,13] The decisive factor for the performance of MB is the reaction mechanism, and multiple battery forms have been expanded into miniaturized power supply as the supplement. Among the MBs mainly represented by lithium-ion batteries (LIBs) with organic electrolyte, various alkali metal ion batteries with abundant resources have been explored for possible substitution of lithium. [14-16] From the perspective of intrinsic safety, aqueous batteries have been developed with the merits of both inexpensive electrolyte and relatively higher power density. [17] Additionally, air batteries derived from fuel cells and ideally comprised of infinite O 2 supply for cathode reaction High-performance miniaturized energy storage devices have developed rapidly in recent years. Different from conventional energy storage devices, microbatteries assume the main responsibility for micropower supply, functionalization, and characterization platforms. Evolving from the essential goals for battery design of high power density, high energy density, and long lifetime, further practical demands for microbatteries (MBs) have been raised for the microfabrication technique and device design. Numerous studies have generally...

“…In 2018, Belovickis et al [12] .studied the dielectric spectrum, ferroelectric and piezoelectric properties of P(VDF-TrFE)/BPZT in the temperature range of 150-420K, and analyzed the relationship between the effective dielectric constant of the composite and the filler concentration by Lichtenecker method. Tang E L et al [13][14][15][16][17] . carried out a large number of dynamic mechanical and electrical performance studies on PZT-5H from 2014 to 2019, and obtained the mechanical response and piezoelectric characteristics of the piezoelectric ceramics under different strain rates, and evaluated the electrical output characteristics of the laminated piezoelectric ceramics under overload conditions, and the influence mechanism of the internal cracks on the discharge characteristics of the ceramics were studied.…”

In order to study the electromechanical characteristics of PZT-5H in the temperature range of -40~25℃ under the impact loading, the electrostatic parameters of PZT-5H at different temperatures are measured, the liquid nitrogen cooling/Hopkinson mechanical property and piezoelectric ceramic voltage output testing system are built, Hopkinson experiments at different temperatures (-40 ℃ , -25 ℃ , -10 ℃ , 0 ℃ and 25 ℃ ) and different impact velocities are carried out. Experimental results show that , the resistivity and relative permittivity decrease with the temperature of PZT-5H decreasing from 25℃ to -40℃, and the relative permittivity decrease about 27.92%, and the relaxation time is also deduced. By scanning electron microscope (SEM) and Energy Dispersive Spectrometer (EDS) observation, it is found that the blowhole defects and cracks of the piezoelectric ceramics have obvious effects on the electrical output characteristics of piezoelectric ceramics when the piezoelectric ceramics are struck. Based on the analysis of space charge theory, the freezing effect of piezoelectric ceramics caused by the obstruction of domain motion at low temperature is obtained. And the dynamic piezoelectric constant in the elastic region measured is about 1.66 times that of the static piezoelectric constant, which indicates that the relative dielectric constant of the piezoelectric ceramic has changed significantly under dynamic loading.
