Mechanical vibrational energy, which is provided by continuous or discontinuous motion, is an infinite source of energy that may be found anywhere. This source may be utilized to generate electricity to replenish batteries or directly power electrical equipment thanks to energy harvesters. The new gadgets are based on the utilization of piezoelectric materials, which can transform vibrating mechanical energy into useable electrical energy owing to their intrinsic qualities. The purpose of this article is to highlight developments in three independent but closely connected multidisciplinary domains, starting with the piezoelectric materials and related manufacturing technologies related to the structure and specific application; the paper presents the state of the art of materials that possess the piezoelectric property, from classic inorganics such as PZT to lead-free materials, including biodegradable and biocompatible materials. The second domain is the choice of harvester structure, which allows the piezoelectric material to flex or deform while retaining mechanical dependability. Finally, developments in the design of electrical interface circuits for readout and storage of electrical energy given by piezoelectric to improve charge management efficiency are discussed.

“…Researchers have used a variety of designs to embed piezoelectric components for mechanical-to-electric energy conversion in floor tiles. These designs are roughly categorised into three primary types: cantilever type [1][2][3][4][5][6][7][8], curved type [9][10][11], and ar-ray/stacked type [12][13][14][15][16][17][18][19][20][21][22], depending on the type of piezoelectric element utilised. However, the most readily accessible piezoelectric energy harvesters are piezoelectric diaphragms, which are simple to attach to any planar surface using an adhesive.…”

Human footsteps are a sustainable energy source that is derived from kinetic energy. As a result, in this study, piezoelectric sensors placed beneath floor tiles were excited by human footsteps to provide practical electrical energy. A simple rectifying circuit with a filter was used to capture electrical power. The floor tile is 455 mm in length and 405 mm in width. Two light-emitted diodes were lit up as the actual load by utilising electrical energy obtained from the kinetic energy generated by human footsteps. The greatest attainable power that could be extracted from the suggested floor tile was 249.6 milliwatts, with an approximate cost of $10.2.

“…Hence, the best performance transducer selection, perfectly positioning the material on the shoe, the most output oriented circuit diagram designed, transporting the total output current to the output storage, are the major concerns to get the expected highest output result [17]. Thus, piezoelectric effect can play an important role as an alternating non-conventional energy source.…”

The mechanical energy harvesting from human body, particularly from the feet, is an alternative process for acquiring potential electricity. Human body weight-pressure produces mechanical energy during walking and running. In this study, a special type of footwear was designed by inserting piezoelectric transducer (PZT) under the heel area to convert the mechanical energy into electrical energy. The experiment has been conducted with a circuit comprising of bridge rectifier, capacitor, and a DC-DC converter with an external output connection. It has been found that the AC voltage maximum is 43 V. When the AC voltage was converted to continuous DC, it was found the voltage decreased drastically. The highest generated energy has been found to be 317.52 mJ for two hours (8000 steps per day). Our special type of shoe and circuit design have demonstrated the feasibility of harvesting the mechanical energy into the electrical energy from piezoelectric materials.
