“…Recently, Wan et al developed a piezoelectric nanogenerator from PVDF–TrFE and polydopamine-coated barium titanate nanowires through the electrospinning process and achieved a maximum output voltage, current, and power of 18.2 V, 1.5 μA, and 12.8 μW, respectively. In other works, Wang et al prepared a device from the cotton cellulose-interfaced maleic-anhydride-grafted PVDF and obtained a maximum power density of 1.72 μW cm –2 . Table S1 in the Supporting Information shows a comparison of previous works with the present work in terms of piezoelectric output values.…”

A flexible and easily processable polymer composite is developed from naturally occurring piezoelectric materials for efficient energy-harvesting applications. Tomato peel (TP)- and cotton (CTN)-based poly(vinylidene fluoride) (PVDF) composites have been prepared and the role of induced electroactive phases have been explored through structural, thermal, and morphological analyses for their applications in energy production. The mechanism of induced piezoelectricity is vividly demonstrated using electromechanical responses and characteristic changes due to induction phenomena. The CTN-based composite generates a maximum output voltage and current of 65 V and 2.1 μA, respectively, as compared to the maximum output voltage and current of 23 V and 0.7 μA in TP-based composites due to the significant induction of the piezoelectric phase in the presence of suitable electroactive cotton. The fabricated device is able to store charges in capacitors and converts the external stress through different motions of the human body to generate a considerable output, which describes the applicability of the material and justifies the potential as an efficient and sustainable biomechanical energy harvester.

“…As a result, the PFM measurement found the average piezoelectric coefficient d 33 reached 19.3 ± 2.9 pm V –1 , which was close to the d 33 of a PVDF film. Besides, the piezoelectricity of cellulose films were also improved by incorporating high-piezoelectric nanofillers such as barium titanate, zinc oxide, and manganese ferrite. − While these approaches indeed increased the composite films’ piezoelectric responses, the effect was primarily contributed by the fillers, while the cellulose merely served as a supporting matrix. − Here, we do not consider this type of strategy intrinsic to piezoelectric CNCs and thus not include them in the comparison.…”

The piezoelectric effect has been widely observed in biological systems, and its applications in biomedical field are emerging. Recent advances of wearable and implantable biomedical devices bring promise as well as requirements for the piezoelectric materials building blocks. Owing to their biocompatibility, biosafety, and environmental sustainability, natural piezoelectric biomaterials are known as a promising candidate in this emerging field, with a potential to replace conventional piezoelectric ceramics and synthetic polymers. Herein, we provide a thorough review of recent progresses of research on five major types of piezoelectric biomaterials including amino acids, peptides, proteins, viruses, and polysaccharides. Our discussion focuses on their structure-and phaserelated piezoelectric properties and fabrication strategies to achieve desired piezoelectric phases. We compare and analyze their piezoelectric performance and further introduce and comment on the approaches to improve their piezoelectric property. Representative biomedical applications of this group of functional biomaterials including energy harvesting, sensing, and tissue engineering are also discussed. We envision that molecular-level understanding of the piezoelectric effect, piezoelectric response improvement, and large-scale manufacturing are three main challenges as well as research and development opportunities in this promising interdisciplinary field.

“…Since the first PENG was fabricated in 2006, there have been extensive utilizations of piezoceramics, piezopolymers, and their composites to approach novel PENGs, including the recent research focus on cellulose. − As the most abundant organic substance on the earth, featured for its sustainable, biocompatible, and eco-friendly properties, cellulose provides an almost inexhaustible raw polymer resource for the development of cheap, bio-safe, and renewable PENGs, which is meaningful to address the problems caused by toxic piezoceramic (e.g., lead zirconate titanate, PZT) , or nondegradable synthetic piezopolymer (e.g., polyvinylidene fluoride, PVDF) . Despite the promising potential, it is still necessary to improve the relatively low piezoelectric coefficient in order to implement cellulose as a reliable piezoelectric material for practical use.…”

Cellulose is emerging as a green and sustainable material in piezoelectric nanogenerators (PENGs) for ambient energy harvesting, although its relatively low piezoelectric coefficient still remains a challenge, hindering the potential applications. In this report, a flexible PENG with considerable energy conversion capacity was fabricated by using a polydimethylsilane (PDMS)-encapsulated cellulose nanofibril (CNF)/ Ti 3 C 2 T x (MXene) composite aerogel film, which is capable of collecting low-frequency energy such as energy from human activities. The use of two-dimensional MXene nanosheets not only optimizes the structural regularity of the CNF network but also induces a local polarization locking to align cellulosic dipoles. This strategy essentially improved the piezoelectric property of cellulose, avoiding the conventional energy consuming method (i.e., electrical poling) to strengthen piezoelectricity. Moreover, the thin layer of PDMS endows the PENG with good mechanical stability and flexibility; meanwhile, it prevents MXene from oxidizing so as to maintain its activity. The optimized CNF/MXene-PENG containing 10 wt % MXene generates a dramatically improved voltage of 30.8 V and a current of 0.49 μA. This work provides an easy and effective pathway to access cellulosic materials with enhanced piezoelectricity, aiming to approach flexible, green, and low-cost PENGs for new-generation electronics.
