'Moth'
The photograph that has won third prize was taken by Dr Ingrid Graz a Research Associate at the Nanoscience Centre in the Electrical Engineering Division.
'My topic is stretchable electronics. I create thin metal films that can be reversibly stretched and remain conductive. PDMS serves as our platform/substrate. PDMS is Polydimethylsiloxane a elastomeric polymer and after being reversibly stretched, comes back to its origninal size and form. These thin-metal films provide a platform for the realization of stretchable electronic circuits. We cast the PDMS into petri dishes by mixing the liquid polymer with a curing agent and after stirring, the mixture is cured for 24 hours at 70 degree Celsius. This photograph shows a multilayer of silicone elastomer (PDMS)/gold/PDMS. The image was taken by optical microscope. There are no manipulations or enhancements to the photograph.'
