Over the last decade, in pursuit to provide suitable alternatives for power supplies of medical devices in regenerative medicine, extensive research on nanogenerators has been developed. Such devices can overcome current commercial battery challenges, including intense heat-on-body complications due to the electrical current during therapeutic usage, leading to protein denaturation, cell structure destruction, and even cell necrosis. In addition, these traditional batteries contain a bulky and heavy structure that prevents them from providing sustainable on body biomedical therapeutic intervention. Furthermore, advantages such as wide-range biocompatible and biodegradable materials, lightweight, and sufficient stretchability for device construction can minimize the side effects of implantable devices, including inflammation or toxicity, as well as eliminate secondary surgery to replace or remove batteries. Triboelectric nanogenerators (TENGs) are associated with harvesting mechanical energy in various forms, among which human body motions can serve as a renewable power source for healthcare systems. This review is written to emphasize the importance of TENG's applications in regenerative medicine and modulation purposes, particularly for the nervous system. Some crucial parameters for implantable consideration are discussed. In the concluding remarks, features for clinical utilization including output efficiency, encapsulation, stability, and miniaturization are suggested as challenges and prospects.

“…23 Recently, some reports have indicated that materials with photothermal effects can be combined with ferroelectric polymers by stacking or blending to endow them with a visible light response. 24–28 Moreover, the flexibility, ease of processing, chemical stability, and biocompatibility of ferroelectric polymers have attracted attention in fields such as flexible electronics, bioelectronics, and energy harvesting. 19,29 However, currently, due to the limitations of photoresponsive components, these materials normally have a narrow range of responsive wavelengths and relatively low photo-electric response.…”

“…23 The composites of the Schiff base crystals and ferroelectric polymer exhibited a relatively strong photo-electric response (open-circuit voltage V OC < 4 V). 27 We chemically modified the Schiff base crystal and found that 2-hydroxynaphthylidene-4′-nitro-1′-naphthylamine (HNAN-NO 2 ) molecules had the best properties. 27 Based on these results, in this work, we systematically investigated the microstructure and photo-electric response of composites of HNAN-NO 2 and P(VDF-TrFE) (poly (vinylidene fluoride-trifluoroethylene)) ferroelectric copolymer with different compositions of Schiff base crystals and explored the potential applications of these composites.…”

“…Noticeably, the experimental specialists have found that bulky monomers, such as trifluoroethylene (TrFE), chlorofluoroethylene (CFE), chlorotrifluoroethylene (CTFE), and hexafluoropropene (HFP), were introduced to copolymerize with VDF to improve their possible electromechanical, pyroelectric, and electrocaloric properties and even induce the formation of relaxor ferroelectrics. ,− Benefitting from their chemical versatility and tunable multifunctionality of VDF-based ferroelectric copolymers, they were widely used to fabricate high-performance energy storage capacitors, ,, energy-harvesting nanogenerators, field effect transistors (FETs), , and nonvolatile memory devices . As these ferroelectric polymers possess perfect flexibility, biocompatibility, and processability, they hold tremendous potential for fabrication of biomimetic devices, such as artificial retina, − artificial synapses, − logical computing systems, and electronic skin. − …”

Ferroelectric polymers have drawn a lot of research concerns recently due to their lightness, mechanical flexibility, conformability, and facile processability. Remarkably, these polymers can be used to fabricate biomimetic devices, such as artificial retina or electronic skin, to realize artificial intelligence. The artificial visual system behaves as a photoreceptor, converting incoming light into electric signals. The most widely studied ferroelectric polymer, poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)], can be used as the building block in this visual system to implement synaptic signal generation. There is a void in computational investigations on the complicated working picture of P(VDF-TrFE)-based artificial retina from a microscopic mechanism to a macroscopic mechanism. Therefore, a multiscale simulation method combining quantum chemistry calculations, first-principles calculations, Monte Carlo simulations, and the Benav model was established to illustrate the whole working principle, involving synaptic signal transduction and consequent communication with neuron cells, of the P(VDF-TrFE)-based artificial retina. This newly developed multiscale method not only can be further applied to other energy-harvesting systems involving synaptic signals but also would be helpful to build microscopic/macroscopic pictures within these energy-harvesting devices.
