“…Recently, 3D-printed piezo-electric materials crossed this barrier and have been developed to convert mechanical movement, impact, and stress from any direction into electrical energy. [182][183][184][185][186][187] This could be highly attractive considering the high abundance of organic and organic-inorganic hybrid piezoelectric materials that are known today. The next step would be fabricating 3D-printed low-cost organic and organic-inorganic hybrid piezoelectric materials for flexible smart sensor devices for high-technology applications.…”

This article provides a comprehensive overview of piezo-and ferro-electric materials based on organic molecules and organic-inorganic hybrids for mechanical energy harvesting. Molecular (organic and organic-inorganic hybrid) piezo-and ferroelectric materials exhibit significant advantages over traditional materials due to their simple solution-phase synthesis, light-weight nature, thermal stability, mechanical flexibility, high Curie temperature, and attractive piezo-and ferroelectric properties. However, the design and understanding of piezo-and ferroelectricity in organic and organic-inorganic hybrid materials for piezoelectric energy harvesting applications is less well developed. This review describes the fundamental characterization of piezo-and ferroelectricity for a range of recently reported organic and organic-inorganic hybrid materials. The limits of traditional piezoelectric harvesting materials are outlined, followed by an overview of the piezo-and ferroelectric properties of organic and organic-inorganic hybrid materials, and their composites, for mechanical energy harvesting. An extensive description of peptide-based and other biomolecular piezo-and ferroelectric materials as a biofriendly alternative to current materials is also provided. Finally, current limitations and future perspectives in this emerging area of research are highlighted. This perspective aims to guide chemists, materials scientists, and engineers in the design of practically useful organic and organic-inorganic hybrid piezo-and ferroelectric materials and composites for mechanical energy harvesting.

“…The electric pressure sensor is a new type of sensor invented in recent years, which typically includes piezoelectric and triboelectric pressure sensors. , The piezoelectric pressure sensors are assembled with piezoelectric materials, such as ZnO, BaTiO 3 , and poly(vinylidene fluoride) (PVDF). The application of pressure to a piezoelectric material induces a deformation in its crystal structure, causing a separation or displacement of charges and generating an electric field or voltage across the material, known as the piezoelectric effect.…”

Over the years, researchers have made significant strides in the development of novel flexible/stretchable and conductive materials, enabling the creation of cutting-edge electronic devices for wearable applications. Among these, porous conductive textiles (PCTs) have emerged as an ideal material platform for wearable electronics, owing to their light weight, flexibility, permeability, and wearing comfort. This Review aims to present a comprehensive overview of the progress and state of the art of utilizing PCTs for the design and fabrication of a wide variety of wearable electronic devices and their integrated wearable systems. To begin with, we elucidate how PCTs revolutionize the form factors of wearable electronics. We then discuss the preparation strategies of PCTs, in terms of the raw materials, fabrication processes, and key properties. Afterward, we provide detailed illustrations of how PCTs are used as basic building blocks to design and fabricate a wide variety of intrinsically flexible or stretchable devices, including sensors, actuators, therapeutic devices, energy-harvesting and storage devices, and displays. We further describe the techniques and strategies for wearable electronic systems either by hybridizing conventional off-the-shelf rigid electronic components with PCTs or by integrating multiple fibrous devices made of PCTs. Subsequently, we highlight some important wearable application scenarios in healthcare, sports and training, converging technologies, and professional specialists. At the end of the Review, we discuss the challenges and perspectives on future research directions and give overall conclusions. As the demand for more personalized and interconnected devices continues to grow, PCT-based wearables hold immense potential to redefine the landscape of wearable technology and reshape the way we live, work, and play.

“…26 When it comes to stretching deformation, the challenges are significantly elevated. There are already several reviews about the progress of printed stretchable electronics; they mainly focus on the realization of stretchability, including printed stretchable sensors, 27 energy devices, 28,29 display 30,31 and data transmission, 32 and lack the overall evaluation of reliability from a system-level view. Even for the realization of stretchability, these reviews mainly focus on the simple implementation of strain, and reliability aspects, such as the strain rate-dependent performance, are rarely discussed.…”
