“…These results indicate that the sensor properly recognizes blood. In addition, the LOD of the sensor is found to be 6 μL, which is lower than that of other recently reported sensors (10 (1) and 15 μL (7) ).…”

“…In this experiment, we chose 10.1, 51.3, and 202 kHz at f 1 , f 2 , and f 3 , respectively, which are the same frequencies as those used in a previous study. (7) Figure 5 shows the capacitance at 10.1 kHz (C 1 ) as a function of the total volume of (a) blood or (b) PBS dropped and the capacitance as a function of the drying time of the sensor on which PBS was dropped (c).

“…For example, a dementia patient may try to remove the sensor unconsciously if the sensor is prominent and causes a feeling of strangeness. Previously, we developed a blood-leakage sensor with detection electrodes fabricated on textiles; (7) however, such a sensor must ultimately be fixed to the body using adhesive tape.…”

We developed a new blood-leakage sensor for hemodialysis therapy. In this sensor, medical gauze is arranged on medical adhesive tape, which contains detection electrodes formed by screen-offset printing. This sensor can be used similarly to an adhesive bandage. We proved that the sensor can distinguish between blood and phosphate-buffered saline (substitute for sweat) on the basis of the dielectric relaxation property of blood. The limit of detection of the sensor is as low as 6 μL, and hence, its performance is considerably better than that of other sensors reported previously.

Textronics—A Review of Textile‐Based Wearable Electronics

et al. 2021

View full text Add to dashboard Cite

Textronics contribute a significant part of Internet‐of‐Things (IoT), which empowers added functionalities by connecting smart clothing in a secure way for diverse applications. For the development of flexible and stretchable textile‐based electronics, a conductive material (yarn, fabric, etc.) must be used, and fabrication techniques play a vital role that significantly influences electronic textiles’ properties. Textile‐based sensors, electrodes, and other devices seem to be the favorite choice for continuous wearable monitoring due to their low cost, flexibility, and ease of embedding. Integrating smart capabilities into textiles provides substantial benefits in the fields of healthcare, sports, automobile, and military. These developments have a profound influence on the Fourth Industrial Revolution (4IR). This Review presents an in‐depth study of the current state of the art in the area of textile‐based electronics. The design, development, and evaluation techniques are discussed. Certain limitations and research gaps are also addressed regarding this emerging field. Critically, this Review is more application focused and indicates how the recent developments in electronic textiles will soon impact our lives. As these areas have typically been neglected in previous reviews, additional knowledge to the existing literature is provided by bridging the gap between the academic research and commercialization of wearable Textronics.

A facile and digital do‐it‐yourself technique is proposed to fabricate inexpensive sensors on flexible substrates (paper, cloth, and plastic film). A set of office‐grade equipment (i.e., laserjet printer, thermal laminator, computer‐aided paper cutter), and commercially available supplies (i.e., baking wax paper, furniture restoration metal‐leaf) are used. Forming electrodes through traditional printing and defining a fluidic confinement region through crafting practice enable fabrication of a wide range of devices without requiring customized specialty instruments, costly infrastructure, and complicated fabrication steps, unlike previously introduced methods. Three different levels of experiments are designed to assess the comprehensiveness and responsiveness of the proposed method to the needs of existing research fields. The performances of the fabricated features at each level are evaluated to cover various application domains in environmental monitoring and biomedical diagnostics utilizing conductometric, colorimetric, biochemical, and chemoresistive detection principles. Devices with varying size of features, from nanometers to centimeters, are fabricated and characterized. This method provides an alternative route to decentralized production of low‐cost flexible sensors and other devices, with a minimal step, time, and facilities. The operation of such devices is simple and can be further empowered by smartphones for data analysis and transmission.
