Flexible and stretchable wearable biomedical devices provide a platform for continues long-term monitoring of biological signals during neutral body movements thus enabling early intervention and diagnostics of various diseases. This thesis evaluates novel flexible and stretchable bio interfacing medical devices based on microneedle patches and split ring resonator for healthcare diagnostics. Flexible and stretchable microneedle patches were realized by integrating a soft polymer substrate with sharp stainless steel microneedles. This was realized using a magnetic assembly technique. Investigations have shown that the flexible microneedle patch can provide conformal and reliable contact with wrinkles and deformations of the skin. In addition, transdermal monitoring of potassium ions using the proposed flexible microneedle patch have been demonstrated by coating the microneedles with a potassium sensing membrane. Ex-vivo test on the microneedle potassium sensor performed on chicken and porcine skin was able to detect change in potassium concentration in the skin. Furthermore, a novel flexible bio-interface spilt ring resonator (SRR) for the monitoring of intera cranial pressure (ICP) is demonstrated. The sensor was fabricated by depositing a 500 nm gold film on a thermoset thiolene epoxy polymer substrate. The flexible sensor was able to clearly detect the pressure variation that might be an indication of increased ICP in the skull. The proposed methodology of heterogeneous integration of hard materials on a soft and flexible substrate demonstrates a first proof of concept of flexible wearable bio-interfacing devices with vastly different material properties with the potential for continuous and real-time health monitoring. / <p>QC 20190306</p>

Approved for public release, distribution is unlimited / As the Department of the Navy and Marine Corps looks for efficiencies in Force End Strength Management and improvement to Sailor and Marine quality of life, Semper Fit may provide some answers. This research specifically focuses on the Marine Corps Body Composition Program (BCP) and Remedial Physical Conditioning Program (RPCP). The purpose is to qualitatively analyze a program for Marines who are overfat or on remedial physical training (PT) programs, focusing on the feasibility of Marines obtaining professional assistance from Semper Fit. The scope of this research evaluates existing programs and analyzes their beneficial affects in improving retention and attrition of RPCP Marines. The research shows that Semper Fit professionals would provide overfat and poorly conditioned Marines by USMC standards a consistent program through mandatory training in health, nutrition, and fitness. Semper Fit would directly support unit commanders with classes in nutrition, health, and fitness tailored for each RPCP Marine. Furthermore, this study validates the newly established Department of Defense Physical Readiness Test Standards recently adapted by the Department of the Navy as highly accurate. This study recommends the Marine Corps further expand Semper Fits role in support of the Marine and unit commander. / Captain, United States Marine Corps

Syfte och frågeställningar. Syftet med studien är att, hos äldre personer, över 65 år, samt hos yngre vuxna, mellan 20-30 år, jämföra syreupptagningsförmågan med två olika metoder, fem-minuterspyramidtest (5MPT) samt VO2max-test på löpband. Vid båda mätmetoderna används direkt syrgasmätning. Metod. Totalt deltog 36 personer i studien, varav 17 äldre personer 65 till 85 år (9 kvinnor och 8 män) samt 19 yngre med en ålder mellan 20 till 35 år (10 kvinnor och 9 män). Deltagarnas syreupptagningsförmåga mättes under 5MPT vid två tillfällen som sedan jämfördes med VO2max mätt via ett maximalt test på löpband vid ett tillfälle. Således utfördes sammanlagt tre mätningar med direkt syrgasmätning, via andningsmask, under ett maximalt löpbandstest samt under två separata tester av 5MPT med minst 48 timmar mellan varje testtillfälle. Utandningsluften analyserades sedan, vid 5MPT för alla, via det trådlösa portabla systemet Jaeger Oxycon Mobile och vid test på löpband för testgruppen med yngre deltagare. För den testgrupp med äldre deltagare användes, vid testet på löpband, den fasta on-line-utrustningen Jaeger Oxycon Pro som är en liknande mätmetod för syreupptag. 5MPT är ett fem minuter långt test där individen från golvnivå, med högsta möjliga tempo, förflyttar sig fram och tillbaka på en 5,50 meter lång sträcka med en centralt placerad trappramp som är pyramidformad och med en högsta central höjd på 0,62 meter. Resultat. Det primära fyndet i studien var att en stark signifikant korrelation (r = 0,99) visade sig mellan direkt uppmätt VO2max under maximalt test på löpband gentemot syreupptagningsförmågan vid 5MPT då båda åldersgrupperna var sammanslagna, uppmätt i l·min–1. Slutsats. Då det i undersökningen visades en stark signifikant korrelation mellan direkt uppmätt VO2max vid 5MPT och ett maximalt test på löpband i l·min–1 för äldre och yngre vuxna ger det indikationer på att 5MPT kan används som en tillförlitlig metod vid undersökning och uppföljning av en persons aeroba förmåga. Fyndet kan vara av värde då det genom mindre kostsamma och enklare metoder går att få ett mått på en persons hälsa i form av aerob kapacitet, vilket är betydelsefullt ur flera hälsoaspekter på individ- och samhällsnivå. / Aim. The purpose of the study was to investigate the results and correlation between oxygen uptake levels (VO2max) at five-minute pyramid test (5MPT) against maximal oxygen uptake test (VO2max) on a treadmill test, both measured by direct oxygen measurement, in elderly people over 65 years and younger adults aged 20-30 years. Method. A total of 36 people participated in the study, 17 elderly people aged between 65 to 85 years (9 women and 8 men) and 19 younger adults aged between 20 to 35 years (10 women and 9 men). The participants' oxygen uptake was measured twice during 5MPT and then compared with VO2max measured by a maximal treadmill test at one occasion. Thus a total of three measurements with direct oxygen measurement, via the breathing mask, during a maximum treadmill test and two separate tests of 5MPT with at least 48 hours between each test. The exhaled air was analyzed at 5MPT for all, through the wireless portable system Jaeger Oxycon Mobile and also during the test on treadmill for the test group with younger participants. The test group of older participants, got their exhaled air analyzed through a stationary on-line equipment Jaeger Oxycon Pro instead of the portable system which is a similar reliable method to measure VO2max. 5MPT is a five minute test where the subjects from floor level, with the highest possible speed, moves back and forth at a measured distance of 5.50 meter with a central staircase ramp, which is pyramid-shaped, with a maximum center height of 0.62 meters. Results. The main finding of the study was that there was a strong significant correlation (r = 0.99) between directly measured VO2max during a maximum treadmill test compared to oxygen uptake at 5MPT when both the elderly people and the younger adults were combined, measured in l·min–1. Conclusion. The study showed a strong significant correlation between directly measured VO2max at 5MPT and a maximal treadmill testing l·min–1 for older and younger adults. This indicates that 5MPT can be used as a reliable method for investigation and monitoring a person’s aerobic capacity. This finding may be of value because it shows that less expensive and easier methods can be used to measure a person's health in terms of aerobic capacity, which is important from several aspects of health at both the individual and society level.
