“…With the exception of electrical performance, productivity is essential for natural materials integrated with bioelectronic fabrication and applications. To satisfy the critical requirements of wearability and implantability, a necessary requirement for all components corresponds to flexibility, biocompatibility, and biodegradability . The other necessary requirement involves controlling the integration of functional materials and devices, especially for biointerface engineering, to endow multifunctional applications in flexible electronics.…”

Organic thin-film transistors, owing to their intrinsic signal transformation and amplification abilities, have emerged as one of the promising biosensing platforms in health monitoring and environmental detection. Natural materials are considered to be important candidates due to the inherent bioactivity, intrinsic biocompatibility, good solution processability, and prominent flexibility. In this paper, we briefly review the progress of organic transistor-based biosensors developed by natural materials and discuss how the physicochemical properties of these materials govern the sensing performance. First, we summarize the fundamental qualities of the natural origins enabled carrier transport, signal transition, mechanical deformation, biodegradability of organic transistors toward biosensing. Then, we highlight recent advances and strategies of how to integrate bionatural materials into wearable and implantable organic transistor-based biosensors. Finally, we propose the challenges and perspectives for the next-generation evaluation of (bionic-)natural species and their potential application in early disease diagnose, biomedical investigation, and smart systems.

“…Nevertheless, as wearable electronics require continuous testing, energy devices are an urgent problem to be solved. Micro-battery delivery systems, flexible large-capacity batteries, supercapacitors, and self-powered systems are the current solutions [ 125 , 126 , 127 , 128 ]. Additionally, the selection of biodegradable and non-toxic materials for wearable sensors is also an issue to be considered for their commercialization.…”

The wearable device industry is on the rise, with technology applications ranging from wireless communication technologies to the Internet of Things. However, most of the wearable sensors currently on the market are expensive, rigid and bulky, leading to poor data accuracy and uncomfortable wearing experiences. Near-field communication sensors are low-cost, easy-to-manufacture wireless communication technologies that are widely used in many fields, especially in the field of wearable electronic devices. The integration of wireless communication devices and sensors exhibits tremendous potential for these wearable applications by endowing sensors with new features of wireless signal transferring and conferring radio frequency identification or near-field communication devices with a sensing function. Likewise, the development of new materials and intensive research promotes the next generation of ultra-light and soft wearable devices for healthcare. This review begins with an introduction to the different components of near-field communication, with particular emphasis on the antenna design part of near-field communication. We summarize recent advances in different wearable areas of near-field communication sensors, including structural design, material selection, and the state of the art of scenario-based development. The challenges and opportunities relating to wearable near-field communication sensors for healthcare are also discussed.

Flexible devices have been rapidly developed and applied in various applications. However, there have been few reports on printable graphene-based sensors with customized structures and properties capable of respiratory and airflow monitoring. In this study, a graphene-based flexible sensor with a conical microdot array (GSCA) made by the direct-ink writing 3D printing method for real-time personal signals and air-coupled detection is reported. GSCA 3D structures with microdot features on the sensing layer can deliver a fast response of below 60 ms and improve the sensitivity by 32.4% (26−78 kPa), 800% (78−102 kPa), and 600% (102−160 kPa) by adjusting the printing parameters. The sensor exhibits a low detection limit of 11.4 Pa and a large detection range with a linear sensitivity of 1.4−509 kPa. The spider leg-like micro-/nanofibers between two adjacent microdots contribute to electron transport and airflow sensing. The results show the feasibility of the graphene-based sensor with dots to recognize air strength and direction for respiration and airflow. Further validation of the GSCA in real-time personal monitoring demonstrates the potential for multitasking wearable sensors.
