Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 35-36).Wearable technology is an emerging multidisciplinary field. When designing wearables, one must draw upon an understanding of: the available soft materials; the motion of the body; as well as comfort, fashion, and social implications. There is a lot of current research exploring manufacturing processes and user's needs for wearable products, but there are not many products available on the market. Medicine is one field that can benefit from the use of these design principles, however. Patients that require constant care or treatment for chronic diseases have few choices available to them in terms of medical devices. Many available medical products focus only on their functionality, and neglect fashion, convenience, and comfort. Arthritis and other rheumatic diseases are the cause of most disabilities in the United States, and cause chronic pain in joints all over the body. There are few non-invasive treatments available to patients suffering with these diseases, so this project seeks to fill that gap in the market. The Selectively Heated Therapeutic Sweater allows the patient freedom to choose where and when heat treatment is applied to their joints throughout the day. It also takes into consideration their right to privacy and makes the treatment as unobtrusive to daily life as possible. Conductive fabric was used as a resistive heater powered by low-profile button batteries. The connections of this battery pack were made by using fabric snaps which allow for temporary placement and easy removal for washing. The sweater functioned as anticipated, but could have been improved through the use of soft battery holders and conductive threads.S.B

Wearable sensor networks: A measurement study

Abstract Wearable technology is no longer science fiction. Thanks to the growing capability in the production chain to miniaturize complex electronics, a wide variety of gadgets that can be worn or included in dresses and accessories have emerged. These smart gadgets can collect data about the physical condition of the user and/or the environment providing the basis for innovative and valuable services. The main goal of this paper is to assess this context through field experiments undertaken in a testbed comprised of sensing hardware deployed on open source boards such as Arduino. Moreover, coupled with the sensing tier, we propose a proof-of-concept deployment architecture enabling a wide range of wearable sensors to collect and transmit data to a logically centralized unit

Design of a man-wearable control station for a robotic rescue system

This report details the design, development, and testing of a man-wearable operator control station for the use of a low-cost robotic system in Urban Search and Rescue (USAR). The complete system, dubbed the "Scarab", is the 1st generation developed and built in the Robotics and Agents Research Laboratory (RARL) at the University of Cape Town (UCT), and was a joint effort between three MSc students. Robots have found a place in USAR as replaceable units which can be deployed into dangerous and confined voids in the place of humans. As such, they have been utilized in a large variety of disaster environments including ground, aerial, and underwater scenarios, and have been gathering research momentum since their first documented deployment in the rescue operations surrounding the 9/11 terrorist attacks. However one issue is their cost as they are not economical solutions, making them less viable for inclusion into a rescue mission as well as negatively affecting the operator‟s decisions in order to prioritise the safety of the unit. Another concern is their difficulty of transport, which becomes dependent on the size and portability of the robot. As such, the Scarab system was conceived to provide a deployable robotic platform which was lowcost, with a budget goal of US $ 500. To address the transportability concerns, it aimed to be portable and light-weight; being able to be thrown through a window by a single hand and withstanding a drop height of 3 m. It includes an internal sensor payload which incorporates an array of sensors and electronics, including temperature monitors and two cameras to provide both a normal and IR video feed. Two LED spotlights are used for navigation, and a microphone and buzzer is included for interaction with any discovered survivors. The operator station acts as the user interface between the operator and the robotic platform. It aimed to be as intuitive as possible, providing quick deployment and minimalizing the training time required for its operation. To further enhance the Scarab system‟s portability, it was designed to be a manwearable system, allowing the operator to carry the robotic platform on their back. It also acts as a charging station, supplying power to the robotic platform‟s on-board charging circuitry. The control station‟s mechanical chassis serves as the man-wearable component of the system, with the functionality being achieved by integration onto a tactical vest. This allows the operator to take the complete system on and off as a single unit without assistance, and uses two mounting brackets to dock the robotic platform. Key areas focussed upon during design were the weight and accessibility of the system, as well as providing a rugged housing for the internal electronics. All parts were manufactured in the UCT Mechanical Engineering workshop

The use of mHealth solutions in active and healthy ageing promotion: an explorative scoping review

The global population aged 60 years and over is expected to almost double between 2015 and 2050 from 12.0% to 22.0%, which will directly impact countries' labor market composition and increase the economic pressure on their healthcare systems. One way to address these challenges is to promote Active and Healthy Ageing (AHA) using mobile Health (mHealth). This research aims to provide an initial overview of the width and the depth of contemporary preventive mHealth solutions that promote AHA among healthy, independent older adults (individuals aged 60 years and over). To do so, an explorative scoping review was applied to search online databases for recent studies (March 2015 - March 2020) addressing the promotion of mHealth solutions targeting healthy and independent older adults. We identified 31 publications that met the inclusion criteria. Most of them utilized either mobile (n=25) and/or wearable (n=11) devices. mHealth solutions mostly promoted AHA by targeting older adults’ active lifestyles or independence. Most of the studies (n=27) did not apply a theoretical framework on which the mHealth promotion was based. User-experience was positive (n=12) when the solution was easy to use but negative (n=11) when the participants were resistant or faced challenges using the device and/or technology. The review concludes that mHealth offers the opportunity to combat the issues faced by an unhealthy and dependent aging population by promoting AHA through focusing on older adults’ Lifestyle, Daily functioning, and Participation. Future research should use multidisciplinary integrated approaches and strong theoretical and methodological foundations to investigate mHealth solutions' impact on AHA behavioral change

IMPACT OF PODCASTING ON LEARNING OUTCOMES IN ASSOCIATE DEGREE NURSING STUDENTS

The dawn of the Information Age has provided rapid advances in technology that have improved lives and produced better tools for caring for each other. Nursing has begun to employ many of these new technologies and nurses are at the forefront of deciding how these innovations might best help patients. New technologies have made their way into schools of nursing and students are benefitting from improved learning experiences. Nursing faculty are leading the way in providing new learning opportunities to students through a multitude of technological advances. One of these advances is podcasting. Podcasting provides students the ability to listen, watch, download and manipulate content in ways that best serve their learning needs. The purpose of this program of study was to examine how technology impacts nursing practice and education. A state-of-the-science paper explored the use of wearable technology as well as provided guidance into how nurses can develop more of these devices. This data ignited a desire to learn about how technology, specifically podcasting, is used in nursing education through the experiences of faculty as well as students. Results from this analysis led to a quasi-experimental research study delving into the use of podcasting for Associate Degree Nursing students. While the results did not reveal a statistically significant improvement in outcomes, a close analysis of the data suggests that further research is warranted to determine if the use of podcasting as a learning supplement may benefit future generations of nursing students

Middleware-Driven Intelligent Glove for Industrial Applications

It is estimated that by the year 2020, 700 million wearable technology devices will be sold worldwide. One of the reasons is the industries’ need to increase their productivity. Some of the tools welcomed by industries are handheld devices such as tablets, PDAs and mobile phones. However, handheld devices are not ideal for industrial applications because they often subject users to fatigue during their long working hours. A viable solution to this problem is wearable devices. The advantage of wearable devices is that they become part of the user. Hence, they subject the user to less fatigue, thereby increasing their productivity. This chapter presents the development of an intelligent glove, which is designed to control actuators in an industrial environment. This system utilizes RTI connext data distributed service middleware to facilitate communication over WiFi. Our experiments show very promising results with maximum power consumption of 310 mW and latency as low as 23 ms. These results make the proposed system a perfect fit for most industrial applications
