With the increasing concerns over global warming and the growing demands for electricity, many researchers have considered renewable and sustainable resources for electricity/power generation. [1] Photovoltaics, thermoelectric, and electromagnetic induction are among the well-established technologies for electricity generation. [2] Mechanical energy is one of the most abundant and available resources that can be harvested to generate electricity. For example, mechanical energy is available in the form of human body motion and mechanical vibration. [3][4][5][6] Piezoelectric and triboelectric nanogenerators have both been used for mechanical energy harvesting. In triboelectric nanogenerators, electrical energy originates mainly from friction or temporary contact of two different layers. However, a wide range of deformation modes like bending, stretching, and vibration can generate electricity using piezoelectric nanogenerators (PNGs). The working mechanisms of PNGs are typically easier than triboelectric nanogenerators. [7] In addition, improving electrical output and reproducibility of triboelectric nanogenerators are still challenges. [8] The use of ferroelectric materials is a promising choice for energy harvesting. Ferroelectric materials show both piezoelectric (generation of electrical power from mechanical oscillation) and pyroelectric (generation of electricity from temperature fluctuation) properties. [9,10] Piezoelectric property offers conversion of mechanical energy to electricity. By applying mechanical stress, dipole momentum forms, leading to spontaneous polarization. Consequently, the electric current flows through the piezoelectric materials as a result of charge accumulation. [11] A wide range of piezoelectric materials is used as PNGs. Piezoelectric materials can be categorized into ceramics, polymers, and piezoelectret polymers. Materials with perovskite or wurtzite nanostructures show piezoelectric properties because their crystals are noncentral symmetry. Ceramics with perovskite

Wearable sensors have gained popularity over the years since they offer constant and real-time physiological information about the human body. Wearable sensors have been applied in a variety of ways in clinical settings to monitor health conditions. These technologies require energy sources to carry out their projected functionalities. In this paper, we review the main energy sources used to power wearable sensors. These energy sources include batteries, solar cells, biofuel cells, supercapacitors, thermoelectric generators, piezoelectric and triboelectric generators, and radio frequency (RF) energy harvesters. Additionally, we discuss wireless power transfer and some hybrids of the above technologies. The advantages and drawbacks of each technology are considered along with the system components and attributes that make these devices function effectively. The objective of this review is to inform researchers about the latest developments in this field and present future research opportunities.

Piezoelectric nanogenerators can convert energy from ambient vibrations into electrical energy. In the future, these nanogenerators could substitute conventional electrochemical batteries to supply electrical energy to consumer electronics. The optimal design of nanogenerators is fundamental in order to achieve their best electromechanical behavior. We present the analytical electromechanical modeling of a vibration-based piezoelectric nanogenerator composed of a double-clamped beam with five multilayered cross-sections. This nanogenerator design has a central seismic mass (910 μm thickness) and substrate (125 μm thickness) of polyethylene terephthalate (PET) as well as a zinc oxide film (100 nm thickness) at the bottom of each end. The zinc oxide (ZnO) films have two aluminum electrodes (100 nm thickness) through which the generated electrical energy is extracted. The analytical electromechanical modeling is based on the Rayleigh method, Euler–Bernoulli beam theory and Macaulay method. In addition, finite element method (FEM) models are developed to estimate the electromechanical behavior of the nanogenerator. These FEM models consider air damping at atmospheric pressure and optimum load resistance. The analytical modeling results agree well with respect to those of FEM models. For applications under accelerations in y-direction of 2.50 m/s2 and an optimal load resistance of 32,458 Ω, the maximum output power and output power density of the nanogenerator at resonance (119.9 Hz) are 50.44 μW and 82.36 W/m3, respectively. This nanogenerator could be used to convert the ambient mechanical vibrations into electrical energy and supply low-power consumption devices.
