“…PZT is fragile and weak when subjected to shear force. However, flexible and stretchable piezoelectric devices have recently been developed and applied for harvesting energy from natural motions of internal organs [10]. In order to maximize the piezoelectric effect, it is necessary to install the PEH in a part of the human body that is subjected to a large compressive or tensile force.…”

“…Such devices should be light weight, and their consumption of metabolic energy should be negligible to ensure the wearer does not feel discomfort. Flexible and stretchable devices would be suitable for these applications [10]. Thermoelectric, triboelectric, piezoelectric, and inertial induction methods will be used, and the outputs will ranges from several µW to several mW.…”

Abstract:Energy harvesting has been attracting attention as a technology that is capable of replacing or supplementing a battery with the development of various mobile electronics. In environments where stable electrical supply is not possible, energy harvesting technology can guarantee an increased leisure and safety for human beings. Harvesting with several watts of power is essential for directly driving or efficiently charging mobile electronic devices such as laptops or cell phones. In this study, we reviewed energy harvesting technologies that harvest biomechanical energy from human motion such as foot strike, joint motion, and upper limb motion. They are classified based on the typical principle of kinetic energy harvesting: piezoelectric, triboelectric, and electromagnetic energy harvesting. We focused on the wearing position of high-power wearable biomechanical energy harvesters (WBEHs) generating watt-level power. In addition, the features and future trends of the watt-level WBEHs are discussed.

The ferromagnetic cobalt doped into Zinc Oxide (ZnO) crystals is a promising method for enhancing the performance of PiezoelectricBased Nano Generators (PENGs). The study reports the characterization and testing PENGs which simply fabricated from cobalt-doped ZnO nanofibers (NFs) synthesized by electro spinning machine. The electro spinning processes were conducted at a flow rate of 4 µL/min and at various cobalt concentrations followed by sintering at a temperature of 500°C. The X-Ray Diffraction (XRD) spectra demonstrate that the crystalline diameter of Co-doped ZnO NFs increased as the content of cobalt increased, up to a concentration of 9%. Meanwhile, the maximum output voltage and power density of PENGs with Co-doped ZnO NFs were 221.6 mV and 148.8 nW/cm 2 , respectively when the PENGs were subjected to a cyclic mechanical load of 0.5 kg. Therefore, PENGs fabricated from Co-doped ZnO NFs are challenging for the next generation of self-powered devices.

The triboelectric nanogenerator (TENG) as a new power-generation technology was reported by Wang and co-workers in 2012. Because of its great potential for scavenging mechanical energy from living environment and sustainably driving portable devices, many researchers have developed various methods to improve output performances of TENG. In this paper, we review the progress in TENG made as flexible power sources by integrating flexible materials and stretching structures, especially for the applications of flexible electronics. For optimizing performances of TENG, the structural designs, material selections, and hybrid energy cells are presented. The reported TENG as flexible power sources has the potential applications in lighting up light emitting diodes (LEDs), powering sensors, and monitoring biomechanical motions.
