This book was released on 2015 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conformal and stretchable wearable sensors provide vital real time information about individual's health conditions. In this work, Traditional printing methods are used for fabrication of stretchable and wearable sensors which can be mounted on the human skin for the purpose of health tracking. In addition, screen printing technology was utilized to develop a printed and flexible electronic circuit board which can be used as a readout circuit along with fabricated wearable sensors. The dissertation is organized and pursued in three projects. In the first project, screen printing was used to fabricate multi-layer PCBs using printed deposited materials on three distinct substrates. The different characteristics of PET, paper and glass as a substrate for PCBs were analyzed. A method for populating electronic components onto the printed PCB pads was established and demonstrated. Different analysis, such as effect of the roughness of the substrates on the electrical performance of the printed lines and the effect of bending on the resistivity of the printed lines were performed. The capability of the printed hybrid PCB circuit to correctly operate and drive an LCD was shown. In the second project, a new method for fabrication of wavy lines and structures was devised for the formation of stretchable and flexible wearable sensors. Thermoplastic polyurethane was used as a substrate in this project. Different wavy structure designs were printed and analyzed to determine the best design rules. Silver and Carbon Nano Tubes were used for fabrication of wavy lines. The printability, bendability and stretchability of all printed lines were tested and analyzed. Different design rules and parameters such as the ratio of the width of the lines to their radius and the length of the extended line to the diameter of the arc were tested and analyzed. Printed wavy structures using CNTs showed below 35 percent change in the resistance when it was stretched and 50 percent strain was applied on the structure. 40 percent change in the resistance of the lines printed using silver was obtained when 10 percent strain was applied. The results obtained demonstrated that CNTs showed a promising potential to be used for fabrication of strain wearable sensors. In the third project, a novel wearable sensing platform for the detection of disorder in body movement, temperature and ECG was fabricated. Both wavy structure and non-wavy structure were implemented in these devices. Silver and CNTs inks were used for the fabrication of different sensing parts on the PDMS and tattoo paper as substrates. The strain sensor fabricated on tattoo paper and PDMS were tested towards bending of finger to angles of 10, 20, 30 and 40 degree. 3.66 percent, 4.7 percent and 4.18 percent change was observed in the resistance for each step for sensor 1, sensor 2 and sensor 3, respectively, on tattoo paper. The printed sensor on the PDMS demonstrated average change of 2.7percent, 2.2 percent and 2.8 percent for sensor 1, sensor 2 and sensor 3, respectively, for each step of bending of finger. The printed sensor on the PDMS was successfully implemented as a temperature sensor for tracking of skin temperature. Mixture of silver and silicone was used for fabrication of flexible electrocardiogram sensor on PDMS. The devices response demonstrates the feasibility of printed multi-functional wearable sensors for health monitoring applications.

Available in PDF, EPUB and Kindle. Book excerpt: For long-term physiological monitoring inside or outside a hospital setting, a reliable, wearable monitoring system would be a convenient platform if biomedical sensors are securely placed in appropriate positions. An article of clothing is an attractive platform to implement such a wearable system. It is highly desirable that the sensors be designed and integrated into the garment in an unobtrusive way. The purpose of the dissertation is to develop textile-embedded biomedical sensors that can be integrated into textile substrates in a seamless manner for long-term ECG and respiration monitoring while normal daily activities including walking, jogging, sleeping, sitting, and other exercise are transpiring. These sensors should provide both a comfortable textile interface and robustness against noise and motion artifacts. For ECG monitoring, we developed textile-embedded active electrodes that transform high input impedance signals to low impedance versions by employing a voltage follower circuit. The fabric active electrodes include a transducer layer on the top of the nonwoven substrates and a circuit layer on the bottom. The transducer area, signal path and power lines are filled with AgD gCl ink by screen printing or hand painting. The electrical components and external wires were attached using adhesive conductive inks and protected by another textile covering layer. For respiration monitoring, we devised a fabric sensor structure based on double nonwoven substrates. Stretchable and non-stretchable segments of nonwoven fabrics are laterally attached by, for example, ultra sonic bonding. The stretchable fabrics are employed in belts around the chest and abdomen and respond to breathing effort by changing the sensor's length in the direction of the strain applied. Rectangular plates for a capacitive sensor or an open-rectangular spiral for an inductive sensor is deposited on the non-stretchable fabric portions of the sensors by printing or painting silver in.
Download or read book Printed Wearable Electrochemical Sensors for Healthcare Monitoring written by Amay Jairaj Bandodkar and published by . This book was released on 2016 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an expected compound annual growth rate of 35% over the next five years, the global wearables market is poised to reach 148 million annual shipments in 2019. One of the alluring factors of wearables is the incorporation of sensors that can monitor a people's well-being and their surroundings in a continuous autonomous fashion. Such continuous stream of vital data thus offers unprecedented avenue in healthcare, defense and environmental domains. Though the attractiveness of wearable sensors is indubitable, this nascent field is marred with several challenges and not much has been done to address these. A major challenge is the unavailability of important wearable sensors. For example, the wearable sensor field is dominated by sensors that monitor physical parameters, for example, motion, pressure, temperature, heart rate and brain-activity sensors etc. One must monitor chemicals in addition to physical parameters in order to obtain a comprehensive knowledge of a person's well-being. Continuous chemical monitoring is important for analyzing fitness levels, alerting people about serious medical conditions, e.g., diabetes, traumatic brain injury, soft tissue injury etc. At present only blood analyzers are available to measure these chemicals. But the intrusive nature of these analyzers, due to blood sampling step, render then impractical for continuous, everyday use. Sensors that can perform continuous non-invasive monitoring of vital chemical biomarkers are thus highly desired, yet missing. The present thesis focuses on filling this technological vacuum by developing body-compliant, skin-worn electrochemical sensors that can detect physiologically relevant chemicals directly on the human skin in a completely non-invasive fashion.
Download or read book A Modular and Stretchable Electronic System for On body Health Monitoring Applications written by Carlos Núñez López and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of current wearable devices used for health monitoring (e.g. Fitbit) are composed of bulky rigid electronics that are not customizable and are too rigid for the skin. To overcome such limitations, a modular system based on thin and stretchable electronic modules was proposed. To link modules together, a novel four pin sliding connector was designed, fabricated, integrated into an stretchable electronic circuit and characterized. The first part of the thesis focused on investigating different stretchable conductive materials that could be integrated into soft rubber substrates. Two materials were tested. First, a commercial silver ink was deposited onto polyurethane rubber (PUR), showing high conductivity but minimum stretchability (below 3% strain). Second, serpentine shaped FPCs were designed and integrated into a silicone substrate, showing stretchability up to 160-170% strain with minimum changes in conductivity (below 30%). Additionally, a tensile cycling test showed stable electromechanical behavior up to 3,500 cycles at 30% maximum tensile strain. The second part of this work addressed the design, fabrication and testing of a novel system for modular stretchable electronics. A four pin sliding connector to enable I2C communication was fabricated by assembling 3D printed parts with brass components manufactured with an EDM cutter. The mechanism could be easily integrated within the previously made stretchable FPC serpentines and demonstrated excellent electromechanical performance. A sample module could be stretched until complete serpentine failure (120% strain) with resistance values across the four pins lower than 2[omega]. Furthermore, the device evaluation on a treadmill showed changes in resistance lower than 4.27[omega] during the 15 minute experiments.
