Multifunctional membranes with outstanding heat dissipation, wave‐transparent, and self‐cleaning performance, as well as strength and ventilation, are urgently needed to meet the rapid development of portable electronics. Herein, we reported an improved phase separation process to prepare thermoplastic polyurethane (TPU)/multi‐wall carbon nanotube (MWCNT) composite membranes with open‐cell porous structure. Their morphology can be manipulated by regulating the content of MWCNT and varying processing parameters. These TPU/MWCNT composite membranes exhibit outstanding mechanical properties. For example, they can possess elastic deformation behavior in a wide temperature range from −50 to 100°C, and bear a load of more than 40,000 times their own weight. Moreover, there is not any obvious crease on the surface of membranes after a forced folding process, indicating their outstanding shape‐recovery ability and elasticity. Furthermore, these membranes have low dielectric constant and loss factor, and they are almost transparent to X‐band electromagnetic waves. What's more, these membranes also show outstanding water‐vapor breathable performance. In addition, MWCNT and open‐cell porous structure endow TPU/MWCNT membranes efficient heat dissipation capacity and good self‐cleaning performance.

The digitization of textiles (textronics) has created new opportunities for integration with conformable sensors to enable unobtrusive, noninvasive, and continuous decoding of vital body signals. This article provides an in‐depth review of the materials and fabrication methodologies used for textronic sensors per their form‐factor in the textile manufacturing process chain—fiber, yarn, fabric, and apparel. Next, it analyzes the performance characterization techniques currently used for these sensors and highlights the needs for standardized test methods in the following aspects: biocompatibility, thermal and tactile comfort, aging, and operation of the biomedical sensing modality at standard human stretch. It also identifies the significance of pretreatment and conditioning reporting of the textile form‐factors based on their impact on mechanical and electric performance of the textronic sensor. The study concludes by recommending a universal testing roadmap for textronic sensors which is expected to veritably complement the work of different standardization committees, including CEN TC‐248/WG‐31, IEC TC‐124, ASTM D13.50, and AATCC RA111.

“…The combined characteristics can be possessed by material design without affecting breathability. Hu et al [73] obtained graphene coated e-textiles through dipping, water treatment, and a subsequent drying step (Figure 3g). After dipping, the fabric is immersed in a water bath where the rapid separation of solvent and water causes the coating to shrink, allowing the fabric structure to remain breathable.…”

Textile-Based Mechanical Sensors: A Review

et al. 2021

View full text Add to dashboard Cite

Innovations related to textiles-based sensors have drawn great interest due to their outstanding merits of flexibility, comfort, low cost, and wearability. Textile-based sensors are often tied to certain parts of the human body to collect mechanical, physical, and chemical stimuli to identify and record human health and exercise. Until now, much research and review work has been carried out to summarize and promote the development of textile-based sensors. As a feature, we focus on textile-based mechanical sensors (TMSs), especially on their advantages and the way they achieve performance optimizations in this review. We first adopt a novel approach to introduce different kinds of TMSs by combining sensing mechanisms, textile structure, and novel fabricating strategies for implementing TMSs and focusing on critical performance criteria such as sensitivity, response range, response time, and stability. Next, we summarize their great advantages over other flexible sensors, and their potential applications in health monitoring, motion recognition, and human-machine interaction. Finally, we present the challenges and prospects to provide meaningful guidelines and directions for future research. The TMSs play an important role in promoting the development of the emerging Internet of Things, which can make health monitoring and everyday objects connect more smartly, conveniently, and comfortably efficiently in a wearable way in the coming years.
