This thesis presents a new approach for fabricating free standing structures on flexible substrates using the screen printing technique. The research addresses electronic textile applications and is intended to provide a new method for realising sensors and complex structures on fabrics. Conventional smart fabric fabrication methods, such as weaving and knitting, are only able to achieve planar structures with limited functionality. Packaged discrete sensors can also be attached directly to fabrics but this approach is unreliable and unsuitable for mass production. The reported materials and the fabrication processes enable free standing structures to be formed by printing functional layers directly on top of the fabric. This reduces the fabrication complexity and increases wearer comfort and the flexibility of the fabric. This research details an investigation into sacrificial materials suitable for use on fabrics. A plastic crystalline material (Trimetlylolethane (TME)) was identified as an appropriate sacrificial material because it sublimates which reduces the chance of stiction occurring. A screen printable TME paste has been achieved by dissolving TME powder in a solvent mixture of cyclohexanol (CH) and propylene glycol (PG). The TME sacrificial paste can be cured at 85 oC for 5 minutes providing a solid foundation for subsequent printed layers. This sacrificial layer can be removed in 30 minutes at 150 oC leaving no residue. EFV4/4965 UV curable dielectric material was identified as an appropriate structural material for use with TME. The feasibility of the sacrificial and structural materials has been demonstrated by the fabrication of free standing cantilevers and microfluidic pumps on fabrics and flexible plastic films. Printed cantilevers, with capacitive and piezoelectric sensing mechanisms, have been demonstrated as human motion sensors. A printed microfluidic pump with a maximum pumping rate of 68 μL/min at 3 kHz has also been demonstrated. Both the cantilever and micropump have been demonstrated, for the first time, on fabrics and polyimide substrates, respectively.

The purpose of the research described in this thesis was to develop a design methodology for Wearable Computing concepts that could potentially embody authenticity. The Wearables community, still firmly rooted in the disciplines of engineering and ergonomics, had made clear its aspirations to the mainstream market (DeVaul et al 2001). However, at this point, there was a distinct lack of qualitative studies on user perceptions of Wearable products. A review of the market research literature revealed significant consumer demand for authenticity in goods and services, and it was this need that drove the program of research. The researcher's experience as a contemporary jeweller led her to question the positivist design processes of Wearable Computers. The ‘borg'-like aesthetics that had come to characterise these products reflected their origins in the laboratory, and implicit configurations of the user appeared to be acting as a barrier to wider adoption. The research therefore looked to Craft as a creative process with a fundamentally different working philosophy to begin building a new methodology for Wearables. Literature reviews of authenticity and Craft were conducted to provide the theoretical framework necessary for a practice-led enquiry into the design process. Further empirical work was undertaken in the form of the comfortBlanket, a concept design project, and a small survey of makers to provide a set of protocols for craft informed design processes. Following this, a suite of wirelessly networked jewellery was designed for a friendship group of five retirement aged women, and built in collaboration with the Speckled Computing Consortium, Scotland. The user centred methodology is informed by Actor Network Theory to account for the agency of the researcher and the event of task based analyses, and includes lifeworld analysis techniques drawn from a range of disciplines such as psychology and experimental Interaction Design. Three data sets collected over the course of two years were analysed using Grounded Theory, and a novel visualisation tool was developed to illustrate potential commitment to the novel concept designs. The methodology revealed a story of what the women made of the jewellery, how they enacted these understandings, and where this process took place. It was found that evaluating concept designs for the everyday and for authenticity require different approaches and that the design process does not end with the user, but with a reflexive analysis by the designer or researcher. In many respects the proposed methodology inverts standard design practices, presenting as many questions as it seeks to resolve. The methodology is presented as a contribution to emerging communities of practice around Wearable Computing, and to those developers seeking to position their products in the everyday. It is a challenging process that embodies authenticity in its post-structural treatment of functionality, the user and evaluation. Finally, the implemented wireless jewellery network represented the first application of Speckled Computing, and it is anticipated that the theoretical frameworks arrived at will also be of interest to Interaction Design and Contemporary Craft.

This thesis sets out to examine the claims to objective reality and authentication in New critical and Structuralist literary theories, concentrating on their claims to "objectivity" and "scientific validity." It examines the nature of these claims in the light of the original ideas proposed by some of the major New critics and structuralists in the development of their respective "sciences" of literary theory. Taking direction from the nature of reality and objectivity shown by the theorists, the thesis then attempts an assessment of the validity of some of the original perceptions and presuppositions concerning scientific objectivity and reality. It proposes that inconsistencies within the literary theories resulted from the theorists' inability to grasp the complexity and fluctuating nature of the borrowed terminology and principles that they were using. It does so by taking a closer look at the development of some of the more influential physical theories and the philosophical ideas raised by these developments. It then uses Feyerabend's work on paradigms, dominance and ideology to attempt an assessment of the reasons for the literary theorists' perceptions and presuppositions regarding objectivity and reality. This amounts to accounting for the specific scientific models chosen as bases, and also to accounting for the desire for the "scientific approach" at all. Its conclusions give an indication of the extent to which these original errors contributed to the theories' necessary adaptations of perspective and eventual loss of influence, and emphasises the need for the total understanding of concepts in one field by researchers in other fields, especially if those concepts are to be used by the researchers with any degree of precision.

The growing accessibility of quantum mechanics and chaos theory over the past eighty years has opened a new mode of world-creating for dramatists. An increasingly large collection of plays organize their fictional worlds around such scientific concepts as quantum uncertainty and chaotic determinism. This trend is especially noticeable within dramatic texts that emphasize a fictional, not material or metafictional, engagement. These plays construct fictional worlds that reflect the increasingly strange actual world. The dominant theoretical approaches to fictional worlds unfairly treat these plays as primarily metafictional texts, when these texts construct fictional experiences to speculate about everyday ramifications of living in a post-quantum mechanics world. This thesis argues that these texts are best understood as examples of speculative fiction drama, and they speculate about the changes to our understanding of reality implied by contemporary scientific discoveries. Looking at three plays as exemplary case studies—John Mighton’s Possible Worlds (1990), Tom Stoppard’s Arcadia (1993), and Tony Kushner’s Homebody/Kabul (2001)—this thesis demonstrates that speculative fiction theories can be adapted into fictional worlds analysis, allowing us to analyze these plays as fiction-making texts that offer nonclassical aesthetic experiences. In doing so, this thesis contributes to speculative fiction studies, fictional worlds studies, and the dynamic interdisciplinary dialogue between aesthetic and scientific discourses.
