Stretchable strain sensors have been proposed for personalized healthcare monitoring or human motion detection in a skin-mountable form factor. For customization and stretchable substrate-compatible low-temperature processing, various printing technologies have been utilized to fabricate strain sensors. Hydrophobic stretchable polymers and low viscosity conductive inks are typically used in printed high resolution strain sensor fabrications. However, directly printed strain sensors on hydrophobic stretchable substrates have shown limited printability in pattern continuity, spatial resolution, stretchability, and linearity. Therefore, there is still a need to develop a simple printing process that can fabricate high-resolution stretchable strain sensors for skin-mountable healthcare electronics. In this work, we developed a simple inkjet printing and substrate transfer process for stretchable strain sensors by optimizing a polymer coating layer for enhancing the printed pattern formation, spatial resolution, and substrate transfer efficiency simultaneously while maintaining the benefits of inkjet printing, such as customizability and large-area applicability. The printed stretchable strain sensors are embedded into a stretchable substrate, improving stretchability up to 45% of strain, which successfully detects various parts of our body, such as wrists, fingers, and arms. Further, the printing process scales down the sensors to 150 μm × 6 mm, and the miniaturization enables distinguishing subtle movements of different fingers.

“…The results showed that the sensor was able to accurately detect and measure the strain caused by different types of movements, including bending and stretching. 181 The use of self-powered sensors based on triboelectric nanogenerators (TENGs) for sports monitoring applications is explored. TENGs are described as power sensors that can be worn by athletes to monitor various parameters related to sports performance, such as body motion, muscle activity, and temperature.…”

“…AgNP improves the conductivity and sensitivity, as shown in figure 4(f), besides adding anti-bacterial properties to the sensor [158]. Spraying Ag ink on an rGO-coated nylon/spandex knitted fabric forms another crack-based conducting network, furthering sensitivity for subtle motions [151]. Besides, ionogels are emerging as a new class of transparent, conductive, and soft composite materials [200].…”

The integration of electronic functionalities into textiles has been under extensive research as its application is witnessed in various fields, including sensing, energy generation, storage, displays, and interfaces. Textiles endowed with flexibility, comfort, lightweight, and washability have been tested as reliable base materials to implement various physical sensors, of which strain and pressure sensors have shown great potential in applications such as healthcare, fitness tracking, and human-machine interaction. Piezoresistive physical sensors have considerable advantages over capacitive and piezoelectric sensors made of textiles. Apart from fibers, yarns, and threads, two-dimensional textile stripes occupy a significant share as substrates in these sensors. This review article discusses the recent progress of 2D textile-based piezoresistive strain and pressure sensors. It covers the latest works in this domain, focusing on different textile choices, conductive material combinations, fabrication methods, additional functionalities like heating, features like hydrophobic properties, and various applications, with tabulations of key performance metrics. For researchers seeking an update on the state of the field, this review would be helpful as it offers insights into trends for further research and product development aimed at meeting the demands of advanced healthcare and other applications.
