Fabrication of micron scale metallic structures on photo paper substrates by low temperature photolithography for device applications (2015)
Journal Article

Using commercial standard paper as a substrate has a significant cost reduction implication over other more expensive substrate materials by approximately a factor of 100 (Shenton et al 2015 EMRS Spring Meeting; Zheng et al 2013 Nat. Sci. Rep. 3 1786... Read More about Fabrication of micron scale metallic structures on photo paper substrates by low temperature photolithography for device applications.

Modelling and Experimental Verification of Heat Dissipation Mechanisms in an SU-8 Electrothermal Microgripper (2014)
Journal Article

Within this work, a microgripper based on a hot–cold arm principle was tested to give a greater understanding of the associated heat dissipation methods. Experiments were conducted in air at atmospheric and sub-atmospheric pressure, and in helium, ar...

Controlled reactive ion etching and plasma regrowth of titanium oxides of known thickness for production of metal-oxide-metal diodes (2013)
Journal Article

The successful production, via two different oxidation processes, of metal-oxide-metal (MOM) diodes is presented. An innovative reactive ion etching and plasma assisted regrowth process has been used to provide oxides, which are in the thickness rang...

Manipulation of exposure dose parameters to improve production of high aspect ratio structures using SU-8 (2012)
Journal Article

The detailed consideration of the chemistry occurring during the fabrication process is very important for SU-8 compared to other photoresists. In SU-8, the solvent does far more than just act as a carrier for the photoactive compounds: it plays a pr...

Microelectrode arrays for electroanalytical sensing : Comparison of electroplating and electron-beam metallisation. (2011)
Journal Article

This paper demonstrates the differences in electrochemical response obtained by two distinct methods of gold microelectrode array fabrication. An array of 306 gold recessed microelectrodes (45 μm in diameter) was fabricated using lithography, metalli...

A thermally actuated microgripper as an electrochemical sensor with the ability to manipulate single cells (2011)
Journal Article

The design and fabrication of a thermally actuated polymeric microgripper incorporating a bare gold working electrode is described. Initial electrochemical tests confirm that the microgripper sensor works as an effective microelectrode, opening up ex...

Fabrication of an in-plane SU-8 cantilever with integrated strain gauge for wall shear stress measurements in fluid flows (2009)
Presentation / Conference Contribution

We present a cantilever fabricated from the polymer SU-8 for the measurement of wall shear stress in fluid flows. The pressure induced deflection of the cantilever, measured using a calibrated and integrated nichrome strain gauge, can be related to t...
