silk composite electronic Textile Sensor for high space precision 2d combo temperature pressure sensing
Small, 2019Co-Authors: Ronghui Wu, Zhaohui Meng, Weidong Yu, Rui Yu, Fan HuAbstract:: Wearable electronic Textiles based on natural biocompatible/biodegradable materials have attracted great attention due to applications in health care and smart clothes. Silkworm fibers are durable, good heat conductors, insulating, and biocompatible, and are therefore regarded as excellent mediating materials for flexible electronics. In this paper, a strategy on the design and fabrication of highly flexible multimode electronic Textiles (E-Textile) based on functionalized silkworm fiber coiled yarns and weaving technology is presented. To achieve enhanced temperature sensing performance, a mixture of carbon nanotubes and an ionic liquid ([EMIM]Tf2 N) is embedded, which displays top sensitivity of 1.23% °C-1 and stability compared with others. Furthermore, fibrous pressure sensing based on the capacitance change of each cross-point of two yarns gives rise to highly position dependent and sensitivity sensing of 0.136 kPa-1 . Based on weaving technologies, a unique combo Textile Sensor, which can sense temperature and pressure independently with a position precision of 1 mm2 , is obtained. The application to intelligent gloves endows the position dependent sensing of the weight, and temperature distribution sensing of the temperature.

human joint angle estimation with an e Textile Sensor
International Symposium on Wearable Computers, 2014Co-Authors: Yu Enokibori, Kenji MaseAbstract:We describe the results of human joint angle estimation with an e-Textile-based stretch Sensor. Joint angle estimation is necessary to predict the details of human posture and implement posture instruction to prevent caregiver's injury in health and medical care. In this study, we focused on the elbow angle. We installed e-Textile Sensors on an elbow support to maintain an ideal setting and a knitted shirt to simulate a daily-use setting. With the elbow support, the correlation coefficient and the rooted-mean-square error in the degree of arc were 0.99 and 5.73 for complete bends. With the knitted shirt, in the same way, the coefficients and errors were 0.92 and 16.52 for complete bends and 0.71 and 7.30 for a daily action sequence. The range of motion of the subject's elbow was about 132°. Thus, our proposed system showed the potentials to detect up to 11 elbow angle patterns with an ideal setting and 9 patterns with the daily-use settings.

e Textile pressure Sensor based on conductive fiber and its structure
Ubiquitous Computing, 2013Co-Authors: Yu Enokibori, Akihisa Suzuki, Yuuki Shimakami, Hirotaka Mizuno, Kenji MaseAbstract:This paper proposes a novel e-Textile-based pressure Sensor. Textile is a common material in our life, used in such items as sheets, seats, and clothing. If these items are equipped with Sensor functions, they can invisibly assist humans without significant lifestyle changes. Our Sensor is suitable for mass production and durable in daily hard use cases. The Sensor is woven with common weaving machines with a special manner and its material is a common low-cost conductive fiber that does not use special and costly materials, such as optical fiber. The Sensor mechanism is supported by the Textile structure; thus our Sensor has durability for frictional force and scratch occurring sometime in daily context. In this paper, we also introduce two example usages of our Textile Sensor: a bed-size body pressure Sensor for anti-pressure-ulcer treatment and a wearable foot-pressure Sensor for walk and skill analyses.

Respiratory Volume Estimation by a Stretchable Textile Sensor
Advances in Science and Technology, 2012Co-Authors: Yu Enokibori, Akihisa Suzuki, Yuuki Shimakami, Koji Ikeda, Tsutomu Kawabe, Kenji MaseAbstract:E-Textiles using fabric Sensors have been studied well for respiration monitoring in recent years; they can estimate respiratory rates and patterns. However, studies of respiratory volume and flow estimation remain unestablished, although they are necessary for the inspection and monitoring of chronic obstructive pulmonary disease (COPD). In this paper, we introduce a new stretchable Textile Sensor and examine how to calculate respiratory volume. The Sensor can stretch up to about 150% (e.g., 13 to 20 cm). The stretch can be detected from the electronic potential changes between conductive fibers. We analyzed the relationships between the respiratory volume and the torso-surface movements using motion capture. In our evaluation, the mean rooted mean standard errors (RMSEs) of the estimated volumes were 0.39 ± 0.17 (L) among four datasets with motion capture and 0.62 ± 0.22 (L) among three datasets with the Textile Sensor. In addition, we successfully drew a similar flow volume curve (FVC) to those captured with a spirometer.

IWBBIO (2) - Textile Sensor Platform (TSP) - Development of a Textile Real-Time Electrocardiogram
Bioinformatics and Biomedical Engineering, 2018Co-Authors: Thomas Walzer, Klaus Meier, Christian Thies, Natividad Martínez MadridAbstract:Being able to monitor the heart activity of patients during their daily life in a reliable, comfortable and affordable way is one main goal of the personalized medicine. Current wearable solutions lack either on the wearing comfort, the quality and type of the data provided or the price of the device. This paper shows the development of a Textile Sensor Platform (TSP) in the form of an electrocardiogram (ECG)-measuring T-shirt that is able to transmit the ECG signal to a smartphone. The development process includes the selection of the materials, the design of the Textile electrodes taking into consideration their electrical characteristics and ergonomy, the integration of the electrodes on the garment and their connection with the embedded electronic part. The TSP is able to transmit a real-time streaming of the ECG-signal to an Android smartphone through Bluetooth Low Energy (BLE). Initial results show a good electrical quality in the Textile electrodes and promising results in the capture and transmission of the ECG-signal. This is still a work-in-progress and it is the result of an interdisciplinary master project between the School of Informatics and the School of Textiles & Design of the Reutlingen University.
