The latest developments in smart systems for improved human lives with advanced biomedical devices have evolved out of multi‐disciplinary scientific studies, including medicine, biology, material sciences, design, manufacturing, artificial intelligence, microelectronics, and so forth. The growth of such intelligent systems is primarily possible with innovative materials, which demonstrate the response to various external stimuli like temperature, heat, moisture, light, electromagnetic field, and chemical alteration. Such materials have been recently fabricated using different additive manufacturing techniques to devise personalized unique, complex, and novel structures that can adjust to external conditions over time and are specifically attributed to 4D printing. Novel materials that can further improve such systems continued to be explored and employed. This review paper investigates the additive manufacturing of functional polymer nanocomposites, which offer compliant structures with flexible manufacturing processes with high strength, low cost, and long‐term stability. This study aims to deliver a comprehensive and deep understanding of the latest developments in materials, design, manufacturing, fundamental mechanisms involved, and future possibilities in this area of research.

“…One is to directly improve the stretchability of each material used in piezoelectric sensors, the other is to design the geometry of the device. Du et al [70] demonstrated high sensitivity and poling-free characteristics of a fully hybrid 3D-printed Te nanowire-based piezoelectric device. In particular, the printed Ag nanowire electrodes showed excellent conductivity and stretchability without sintering.…”

populations. Moreover, with the advent of the novel coronavirus disease (COVID-19), significant investment in medical resources is required. Under the umbrella of the global COVID-19 pandemic, the use of biosensors in healthcare and online medical care are becoming ubiquitous, which represent methods that can be used to detect signs from the human body for further health analysis. Furthermore, the internet of things (IoT) technology in healthcare is a method by which biosensorembedded objects can be worn on the human body in everyday life that continuously measure and digitize health information without any burden to the wearer. [1] Recently, various biometric technologies have been developed, wearable devices such as smart watches, invasive biodevices, and devices that sense the everyday surrounding environment of the wearer. Medical data can be collected using such devices, which can then be further analyzed by artificial intelligence (AI). These data can then be used for health promotion, prevention of disease, and early disease diagnosis. Moreover, with the advent of COVID-19, healthcare IoT (HIoT) technology has become extremely important. [2] In terms of the individual, when a mask is constantly worn it may cause lung damage to the user. Therefore, the HIoT would make a significant contribution in this case to offer forewarning about the situations of the lungs As society advances, the shift from passive medical care to health management and preventive medical care has become an important issue, with the realization of wearable monitors becoming desirable. In light of the COVID-19 pandemic, the number of patients who are in urgent need of the monitoring of biological information is increasing. This review focuses on piezoelectric materials and composites that convert kinetic energy into electrical energy to realize self-powered wearable monitoring sensors, outlining the recent research activity on sensors for use in healthcare monitoring. First, a general description of the principles of piezoelectric monitoring sensors is given. Next, the development status of piezoelectric materials and composites aimed at the application of detecting tiny motions of the human body is introduced, and then the research trends on the detection of larger human body movements are highlighted. Finally, after presenting the performance of current piezoelectric sensors and future research guidelines for developing multifunctional systems in the post COVID-19 era, the achievements are summarized. Overall, this review will provide guidance to researchers who are seeking to design and develop highly sensitive self-powered piezoelectric sensors that monitor human motion and physiological signals.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/admt.202200318.

The improvement of wearable electronics is making energy harvesters appealing, as they lessen the requirement for regular recharge of wearable gadgets. In this work, fully printed, flexible piezoelectric nanogenerators (PENGs) with excellent performance are created using a 3D printing technology. This fully-printing method is based on triethoxyvinylsilane (TEVS) coated barium titanate (BTO) nanoparticles, polyvinylidene fluoride-co-trifluoroethylene (PVDF-TrFE), and silver electrode for additive manufacturing. The organic vinyl silane (VS) functional groups, which form a strong bond between inorganic nanoparticles and polymer, contribute to the homogeneous dispersion of BTO nanoparticles in the matrix. Consquently, these fully printed VS-BTO/PVDF-TrFE PENGs outperform their untreated counterpart in terms of output voltage and power density, with a higher output voltage of 54 V even after 13 500 cycles and a higher power density of 28.5 μW cm −2 . In practice, as-printed devices may actively adapt to human movement and detect the pulse from multipoint mechanical activity identification. The fully printed PENGs developed in this work show excellent potential to be used in wearable electronics for a new generation of sensing applications.
