“…Energy harvesting technologies which generate electricity using naturally occurring energy are classified roughly by the energy source. Sources of energy utilized by energy harvesting include electromagnetic waves [6][7][8][9], thermal energy [10][11][12][13], chemical energy [14,15], solar energy [16][17][18][19], and kinetic energy [20][21][22][23]. Of these, kinetic energy is distributed unevenly throughout the environment and is easy to use.…”

“…Bassiano et al [23] also enabled low-frequency vibration power generation by bending motion of the macrofiber composites patch (MFCs), and their power generators generate power by bending motion of 0.5 to 2.5 Hz, but it is considered that their device is disadvantageous at 3 Hz or more, due to the durability of the flat plate composite resin. Furthermore, there is a possibility that heat will be generated due to internal friction of the component even for a bending motion of 5 Hz or more, which is also disadvantageous for durability at a high frequency.…”

The movement of the creature and the almost wave in the ocean is a low vibration of random energy with a frequency range of 0.1-10 Hz. Because of its low frequency, the opinion has been that electrical energy generation from this low-frequency wave motion through the electromagnetic induction method is difficult. In this study, an electrical generator was created by the electromagnetic induction method by putting a small mass of ferromagnetic powder in nonmagnetic fluid. A broadband vibration energy harvesting model was created in which vibrations are broadened through a multi-degree of freedom oscillation system using ferromagnetic powder. To generate electricity from low-frequency vibrations (1 Hz or less), a non-resonant type model was created by adding fluid to the ferromagnetic powder model and the simulation results confirmed using computational fluid dynamics by creating a working energy harvesting device.

“…For example, knees, elbows and ankles are candidate locations for placing these materials as depicted in Figure 1. Despite the promise of this approach to solve comfort concerns, very few studies investigated the energy harvesting potential of flexible piezoelectric patches [11,12]. Furthermore, these prior studies follow a purely experimental approach and do not model the energy harvesting mechanism.…”

Motion energy harvesting is an ideal alternative to battery in wearable applications since it can produce energy on demand. So far, widespread use of this technology has been hindered by bulky, inflexible and impractical designs. New flexible piezoelectric materials enable comfortable use of this technology. However, the energy harvesting potential of this approach has not been thoroughly investigated to date. This paper presents a novel mathematical model for estimating the energy that can be harvested from joint movements on the human body. The proposed model is validated using two different piezoelectric materials attached on a 3D model of the human knee. To the best of our knowledge, this is the first study that combines analytical modeling and experimental validation for joint movements. Thorough experimental evaluations show that 1) users can generate on average 13 W power while walking, 2) we can predict the generated power with 4.8% modeling error.

“…The "smart clothes" new fabric harvests energy from its wearer [5][6][7], i.e., using piezo elements incorporated in the wearable patch which generate the usable electric energy. The authors in Reference [8] investigated an optimal inertial power harvester for human-powered devices, where the output power seems to be useful for continuously operating motion powered wireless health sensors and other low-power devices. On the other hand, the electronics industry also strives to reduce electric energy consumption by replacing sensors with the low-power ones.…”

The paper presents the design, fabrication, and characterization of an energy harvester for an active magnetic bearing (AMB) rotor vibration using a macro fiber composite (MFC) with magnetic coupling. The MFC cantilevers configuration, together with neodymium magnets, is used for the contact-free rotor radial vibration self-powered sensor. The permanent magnets attached to the rotor and to the four MFC element beams ensure the mechanical energy transfer and the MFC cantilever vibration excitation. In the proposed prototype, the MFC transducer output voltage depends on the air-gap between two magnets. This paper investigates the optimum conditions to harvest as much as possible electric energy at different clearances and rotational speeds. Furthermore, to assess the rotor vibration sensitivity, the experimental results of the MFC-magnet self-powered sensor are compared with measurements obtained using a fiber optic sensor. The maximal obtained harvesting power equals 673.47 µW for the rotor speed of 3150 rpm. Moreover, the MFC cantilever was proposed as the rotor vibration sensor. The MFC-magnet self-powered vibration sensor output was compared with the fiber optic laser sensor. The mismatched vibration amplitude for both sensors does not exceed 1 µm.
