Nano quill and key ring

Nanotechnology Victoria (NanoVic), a company committed to the development and promotion of nanoscience in Victoria engaged Kennovations to generate concepts for fun, educational and safe objects which both utilise and promote the practical application of nanotechnology.
NanoVic decided on two concepts as their ‘mascots - ‘Eddie the Echidna’ and ‘NanoMan’. ‘Eddie the Echidna’ features quills of NiTinol Shape Memory Alloy which react to specific environmental temperature changes. In general shape memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original, cold-forged shape: returning the pre-deformed shape by heating. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems. Shape memory alloys have applications in industries including medical and aerospace.Nickel Titanium (also known as Nitinol) is the unique class of materials known as shape memory alloys. A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties.

But here the incorporation of shape memory alloy acts depending on the temperature .Below 15°C the 'Eddie the Echidna' quills can be laid flat or messed about in any position, but with the application of heat over 15°C will instantly spring back into the spiked position. ‘NanoMan’ is a super-hero polyurethane key ring featuring a battery powered UV LED backpack and chest plate impregnated with UV reactive nano-polymers.

Nanoscale Physics Research Laboratory, The University of Birmingham has developed a "Nanoman". The "Nanoman" was created by focussed electron beam deposition on the tip of an STM - an illustration of 3D nanostructure fabrication with a precision of 10nm.
