“…In addition to inorganic piezoelectric materials, organic piezoelectric materials such as polyvinylidene fluoride possess the ability to convert mechanical stress into electricity, and represent the most widely available piezoelectric polymer in functional materials and devices due to their physical characteristics of transparency and mechanical flexibility [45,84,90,[170][171][172][173][174][175]. In addition, specific biomaterials, such as collagen, exhibit piezoelectric properties which have been linked to the promotion of healing and reconstruction, due to the polar uniaxial orientation of molecular dipoles in the structure [10,85,[176][177][178].…”

“…The deformed internal and external sides correspond to the faces subject to compression and tension, respectively. [85]. In addition, piezoelectricity can also be found in different parts of living body, such as deoxyribonucleic acids (DNA), cartilage, tendon, dentin, ligaments, skin, as well as cell membranes, which plays a significant role in physiological phenomena for the living body [187][188][189].…”

“…Noris-Suarez have reported bone healing due to piezoelectricity. 86 Bone healing and growth are controlled by the rate of deposition of hydroxyapatite (HA) and their work showed that the piezoelectric dipoles produced by deformed collagen can produce the necessary precipitation of HA. Therefore there is scope to harvest biomechanical motion for enhanced bone growth.…”

Energy harvesting is a topic of intense interest that aims to convert ambient forms of energy such as mechanical motion, light and heat, which are otherwise wasted, into useful energy. In many cases the energy harvester or nanogenerator converts motion, heat or light into electrical energy, which is subsequently rectified and stored within capacitors for applications such as wireless and self-powered sensors or low-power electronics. This review covers the new and emerging area that aims to directly couple energy harvesting materials and devices with electro-chemical systems. The harvesting approaches to be covered include pyroelectric, piezoelectric, triboelectric, flexoelectric, thermoelectric and photovoltaic effects. These are used to influence a variety of electro-chemical systems such as applications related to water splitting, catalysis, corrosion protection, degradation of pollutants, disinfection of bacteria and material synthesis. Comparisons are made between the range harvesting approaches and the modes of operation are described. Future directions for the development of electro-chemical harvesting systems are highlighted and the potential for new applications and hybrid approaches are discussed.

“…The piezoelectric effect determines the construction of anatomical bone structures. The piezoelectric effect in bones is also used in the treatment of osteoporosis, where the noninvasive electromagnetic stimulation prevents bone loss by inducing currents, that stimulate bone formation [2][3][4].…”

Despite growing number of literature demonstrating the piezoelectric effect in bones at macro level there's still a lack of papers describing this effect at molecular level. In order to examine this effect more specifically, a study has been conducted to show the possibility of using infrared spectroscopy on samples contained in the electric field. This is the first known research on applying infrared spectroscopy to study the influence of electric field and compressive stress on bones' structure represented by the molecular IR spectrum. The samples used in this experiment as a model were prepared in pellet form, made from powdered pig's shin bone mixed with KBr (mass ratio of about 1:100). The spectra were obtained in transmission mode. Three different types of experiments were performed at each sample, which were subjected to: (a) fixed electric field (E < 40 kV/m), (b) variable electric field (0-40 kV/m), (c) compressive stress (P < 100 MPa). The obtained data have shown that the electric field and compressive stress on sample modified infrared spectra of the bone. Qualitative as well as quantitative changes in the spectral range between 900 cm −1 and 1200 cm −1 and the band at 562 cm −1 (PO 3− 4 asymmetric and symmetric stretching, respectively) were observed. The relative area obtained by decomposition of the PO 3− 4band reaches an extreme value in the external compressive stress (10 MPa), that occur under physiological conditions. Based on presented data, it was proved that the applied factors (electric field, compressive stress) can change the oscillation energy and the number of molecule's degrees of freedom.
