Book Description
Accurate and reliable in vivo measurement systems for orthopedic applications will allow a better understanding of native joint loading, gait patterns, and changes during healing and tissue regeneration. Robust and reliable telemetry units with an implantable transmitter and data acquisition software are necessary to insure long-term measurements. It was the goal of this study to update the current implantable telemetry system. Updates included using a new tablet computer for increased rates of data acquisition and encasing transmitters in a new waterproof casing. Software was developed using Labview on a Windows based Acer Iconia Tab. The Labview program allowed the user to save data to a measurement file and view the data in real time. The increased processing power of the tablet resulted in an increase in data collection rates from 29Hz to 87Hz. Interfacing the tablet computer with the telemetry system required the use of a RS-232 protocol to USB adapter. The newly developed tablet computer system was also used for load measurement collection during the most recent in vivo study. In order to insure transmitter function in vivo it was necessary to characterize the factors affecting transmission in vivo and develop transmitter and power coil designs that operated reliably. In the past implantable transmitters were noted to operate properly during bench top testing, but often failed after being placed in vivo. The two factors studied that limited power transfer to the transmitters were immersion in an aqueous environment and exposure to elevated temperatures. An aqueous environment significantly decreased power transfer by 11.9% (p-value = 0.014) relative to testing on the bench top. Additionally, a temperature increase to 40°C decreased power transfer by 6.2% (p-value = 0.017) when compared to power transfer in room temperature air. A solution that restored transmitter function required encasing transmitters in a new waterproof casing. Different casing designs made of silicone and semi-solid triglycerides were developed and tested on the bench top. Two different casing designs were used during in vivo testing and implanted into test animals. One casing design insured transmission while the other separated in vivo and did not facilitate transmission.

Book Description
Advances in technology have produced a range of on-body sensors and smartwatches that can be used to monitor a wearer’s health with the objective to keep the user healthy. However, the real potential of such devices not only lies in monitoring but also in interactive communication with expert-system-based cloud services to offer personalized and real-time healthcare advice that will enable the user to manage their health and, over time, to reduce expensive hospital admissions. To meet this goal, the research challenges for the next generation of wearable healthcare devices include the need to offer a wide range of sensing, computing, communication, and human–computer interaction methods, all within a tiny device with limited resources and electrical power. This Special Issue presents a collection of six papers on a wide range of research developments that highlight the specific challenges in creating the next generation of low-power wearable healthcare sensors.

Book Description
Biosocial Surveys analyzes the latest research on the increasing number of multipurpose household surveys that collect biological data along with the more familiar interviewerâ€"respondent information. This book serves as a follow-up to the 2003 volume, Cells and Surveys: Should Biological Measures Be Included in Social Science Research? and asks these questions: What have the social sciences, especially demography, learned from those efforts and the greater interdisciplinary communication that has resulted from them? Which biological or genetic information has proven most useful to researchers? How can better models be developed to help integrate biological and social science information in ways that can broaden scientific understanding? This volume contains a collection of 17 papers by distinguished experts in demography, biology, economics, epidemiology, and survey methodology. It is an invaluable sourcebook for social and behavioral science researchers who are working with biosocial data.

Book Description
M. C. Roco and W.S. Bainbridge In the early decades of the 21st century, concentrated efforts can unify science based on the unity of nature, thereby advancing the combination of nanotechnology, biotechnology, information technology, and new technologies based in cognitive science. With proper attention to ethical issues and societal needs, converging in human abilities, societal technologies could achieve a tremendous improvement outcomes, the nation's productivity, and the quality of life. This is a broad, cross cutting, emerging and timely opportunity of interest to individuals, society and humanity in the long term. The phrase "convergent technologies" refers to the synergistic combination of four major "NBIC" (nano-bio-info-cogno) provinces of science and technology, each of which is currently progressing at a rapid rate: (a) nanoscience and nanotechnology; (b) biotechnology and biomedicine, including genetic engineering; (c) information technology, including advanced computing and communications; (d) cognitive science, including cognitive neuroscience. Timely and Broad Opportunity. Convergence of diverse technologies is based on material unity at the nanoscale and on technology integration from that scale.
