Title & Abstract

Mr Markus Ardron

PhD Student

Heriot-Watt University

Title: Diffractive feature formation on metal

Abstract: By laser melting of a metal surface the predictable generation of a surface profile can be achieved by the sum of various forces in the melt region causing surface movement that is preserved on solidification. Material make-up and laser parameters are being investigated to identify a stable production method.

Title: Electro Swelling

Abstract: The poster presents a novel manufacturing technique for the creation of hollow microfluidic structures such as microchannels in single process step. The technique is based on the Coulombic attraction of polymers between two electrodes. The technique also allows the manufacturing of continuous profile microstructures such as sinusoidal gratings.

Title: Development of a virtual platform using haptic devices for Surgical Training

Abstract: Multidisciplinary teamwork and technological development have enabled the creation of virtual simulators as an alternative tool in surgical training. The application of these tools using haptic devices will enable surgical planning to be fast, non-intrusive and safe for the patient. This project will simulate the bilateral ramus osteotomy for medical support.

Title: Texture Browsing Environments

Abstract: Browsing Environments offer an alternative to search-by-query and can address difficulties with finding/creating good quality query images and the problem of repetitive queries becoming trapped among a small number of undesirable images. We propose three novel browsing environments and test their efficiency and accuracy.

Title: Integration Of Fibre-Coupled ns-Laser Into A Parallel Robot

Abstract: Usage of robots for manufacturing applications in the automobile, printed circuit board and aerospace industry became standard practice during the last two decades. An alternative design to the serial robots commonly used in industry up until now is the PARALLEL ROBOT, where the end effector is connected to the base via multiple kinematic chains. This project integrated a fibre coupled nanosecond laser into a Renishaw-developed parallel robot, for material processing of metals & ceramics.

Title: Compliant parallel manipulators and disassembly-free reconfigurable parallel manipulators

Abstract: First we present the design of a decoupled large-range compliant parallel manipulator for nano-positioning.

Then, we illustrate the working principle of a class of disassembly-free reconfigurable manipulators –

the next generation of multi-arm like parallel manipulators which can adapt rapidly to changing

production requirements – being developed at HWU.

Title: Micro-cantilever sensors

Abstract: Micro-cantilever sensors are attracting much attention as promising solutions for highly sensitive detection of bio-molecules without the need for fluorescent or radioactive labeling. 

In this research we aim to manufacture microcantilevers onto the end of an optical fibre thereby combining the sensing element and the interrogation system into one compact device to enable biosensing applications in space constrained environments.

Title: Real-time monitoring of yeast cell growth using microcantilever sensors

Abstract: Microcantilever sensors have great potential for highly sensitive, selective, and label-free analysis of biomolecules and cells including DNA, proteins, bacteria, and viruses. Here we report the real-time cell growth measurement in physiological environment using microcantilever sensors by monitoring the growth induced bending of cantilever beams which could lead to promising applications in rapid disease diagnosis, environmental monitoring and food safety.

Title: Development of a hybrid micro machining process and its test-bed

Abstract: The poster presents research work on development of new hybrid micro machining processes for manufacturing 3D micro products/components. This includes a process which combines micro milling with laser burring to obtain high quality microfluidic mould or chips; a laser assistant micro grinding process in which laser is used to preheat and repair the subsurface damage of the brittle workpiece materials; an on-line structuring milling cutter approach to obtain long tool life. Conceptual design for a hybrid micro machining centre as a test-bed is also presented in the poster.

Title: Does Highlight Disparity Improve Perception of Gloss on Rough Surfaces?

Abstract: We present results from a pilot study which investigated the effect that highlight disparity has on the perception of gloss on rough surfaces. These experiments seem to imply that the relationship
between gloss perception, highlight disparity and roughness is more complex than previously reported.

Title: CO2 laser based rapid prototyping of autonomous microfluidic systems

Abstract: Laser etching/ablation based micro fabrication allow for reasonable quality microfluidic features to be manufactured within minutes and at a fraction of the cost of standard techniques. Laser etching was implemented to construct various microfluidic systems, which allowed for the actuation and control of a test fluid using capillary forces

Title: Ultrasound Transducer Packaging

Abstract: High frequency ultrasonic transducers for medical applications such as tumour ablation and imaging are required to be fitted in a needle size cavity whilst the transducer itself involves small feature pitch down to below 50 µm and high density interconnections. This poster presents the constraints imposed by ultrasound and how microsystems packaging technologies are employed to overcome those challenges.

Title: Interactivity to Enhance Perception: Increased interactivity in mobile visual presentation tools facilitates more accurate rating of textile properties

Abstract: As part of the EPSRC funded 'Digital Sensoria' project a set of digital tools were utilized to better demonstrate the tactile qualities of textiles via the internet. We tested if interactivity added by Shoogle textile simulator for iPad helps more accurately describe textile qualities. Findings suggest that better visual aids enable better understanding of fabric and new interactive models need to be developed.

Title: Are single still images sufficient to communicate qualities of texture-rich products?

Abstract: Single images have been used extensively over the last decade to present texture-rich products on the web. Recently, rich-media like short videos and animations have started to change and improve the way we view and perceive these products. However, do they communicate texture qualities more reliably than single images?

Title: Open-Ended Single Mode Resonant Microwave Applicator for Electronic packaging applications

Abstract: The possibility of an open ended microwave oven to be placed onto a pick and place machine allows the individual curing of components on a PCB board which is an attractive technological proposition for rework and the assembly of low-thermal budget devices. The basic design of the open-ended single mode resonant applicator creates a resonance within the dielectric block, whilst the fields in the air filled section are below cutoff and therefore evanescent thus resulting in zero level of radiation from the open end of the resonant applicator. Such a configuration is therefore advantageous as a system capable of selected encapsulation of microelectronic devices.ACKNOWLEDGMENTS

Title: How Mesoscale and Microscale Roughness Affect Perceived Gloss

Abstract: We study how mesoscale and microscale roughness affect perceived gloss. We conducted psychophysical experiments using random phase 1/fβ noise surfaces with varying mesoscale roughness by sampling the roll-off factor β, and rendered them using a reflectance model with different microscale roughness by sampling its parameter α. Eight observers took part in a 2AFC experiment, and the results were tested against a conjoint measurement model. The statistical test shows that the additive model is sufficient to describe the interactive influence of mesoscale and microscale roughness on perceived gloss, while α has a trend to shift the peak of gloss induced by β in the full conjoint measurement model.

Title: Haptic Soldering & Knowledge Capture

Abstract: The research aims to identify the motor skills and techniques involved in achieving a good soldering process. If this soldering knowledge was able to be captured, this would allow the development of automated soldering processes that work more efficiently. By simulating the manual soldering process in a haptics environment, the aim is to employ automated user logging to investigate human hand dexterity and learn how novices and experts operate differently.
