Piezoelectric nanogenerators with large output, high sensitivity, and good flexibility have attracted extensive interest in wearable electronics and personal healthcare. In this paper, the authors propose a high-performance flexible piezoelectric nanogenerator based on piezoelectrically enhanced nanocomposite micropillar array of polyvinylidene fluoride-trifluoroethylene (P(VDF-TrFE))/barium titanate (BaTiO ) for energy harvesting and highly sensitive self-powered sensing. By a reliable and scalable nanoimprinting process, the piezoelectrically enhanced vertically aligned P(VDF-TrFE)/BaTiO nanocomposite micropillar arrays are fabricated. The piezoelectric device exhibits enhanced voltage of 13.2 V and a current density of 0.33 µA cm , which an enhancement by a factor of 7.3 relatives to the pristine P(VDF-TrFE) bulk film. The mechanisms of high performance are mainly attributed to the enhanced piezoelectricity of the P(VDF-TrFE)/BaTiO nanocomposite materials and the improved mechanical flexibility of the micropillar array. Under mechanical impact, stable electricity is stably generated from the nanogenerator and used to drive various electronic devices to work continuously, implying its significance in the field of consumer electronic devices. Furthermore, it can be applied as self-powered flexible sensor work in a noncontact mode for detecting air pressure and wearable sensors for detecting some human vital signs including different modes of breath and heartbeat pulse, which shows its potential applications in flexible electronics and medical sciences.

systems and makes them inconvenient for users. [9][10][11] In addition, the periodic exchange of the primary battery causes an enormous waste of resources and complex maintenance problems. [12][13][14] Although the ultralow power consumption system and the high capacity battery can extend the WSN system's operation time, it cannot ensure continuous operation of the system for decades. [15] Thus, an energy harvesting system that converts wasted ambient environment energy into valuable electric energy is one of the important technologies for a future sustainable society. [16][17][18] There are various energy harvesting systems, such as piezoelectric, [19][20][21][22] triboelectric, [23][24][25] thermoelectric, [26][27][28][29][30][31] pyroelectric, [32][33][34] photovoltaic, [35][36][37] and water evaporation-based energy harvesting systems [38,39] and those using green energy sources such as solar, wind, wave, heat, and vibrations. These renewable energy harvesting systems have been receiving great attention in the field of research into renewable and sustainable energy harvesters (EHs) to realize self-powering smart WSN systems and self-charging electronics. [40][41][42][43][44][45][46] The output performance of energy harvesting systems has rapidly improved, and WSN systems and energy harvesting systems have been combined. These two advancements have resulted in extend operation times of small electronic devices. Specialized EH, which uses one kind of green energy, is efficiently converting energy, but this system is fatally flawed because it is influenced by weather conditions. For example, biomechanical energy-based harvesters can generate energy both indoor and outdoors, but specific targeted biomechanical movement is required. [47] Thus, unexpected mechanical energy or other thermal and solar energy is wasted. Similarly, solar EHs can effectively harvest energy under illumination from the sun, but constantly changing weather conditions place constraints on solar cell performance. [48] Furthermore, thermal energy generated by mechanical energy or solar energy is wasted without additional thermal EHs. [49] Therefore, to prevent the useless wasting of energy by a single energy harvesting system, utilizing plural green energy harvesting systems is a countermeasure for sustainable energy harvesting, so that otherwise wasted energy is fully utilized with high energy conversion efficiency, which can power WSN systems at anytime, anywhere.Nature and artificial energies, such as solar, wind, wave, heat, machine vibration, automobile noise continuously exist, so Recently, sustainable green energy harvesting systems have been receiving great attention for their potential use in self-powered smart wireless sensor network (WSN) systems. In particular, though the developed WSN systems are able to advance public good, very high and long-term budgets will be required in order to use them to supply electrical energy through temporary batteries or connecting power cables.
