Carbon Nanotube (CNT); carbon nanotube sheet actuator; functional model

The use of carbon nanotubes (CNT) and ionic liquid within polymer based composites has long been a subject of intense research and great scientific interest. Up till now geometry has been a governing factor on the displacement properties of actuators. For example long thin actuators generate a larger displacement, circular provide more force and ultra thin actuators move at a much higher frequency. Furthermore the incorporation of many actuators into stacks with an aim of multiplying any given characteristic (force, displacement, speed) has also been studied. Lastly the interaction between contact electrodes and multiple actuator systems has been a governing parameter often neglected.
Within this poster a systematic approach that was taken in order to test, characterise and optimise each type of variable with an aim of producing, from an engineering point of view, a working functional model mimicking real life applications, will be presented. In addition the interaction between the three main parameters will be explored. The fundamental factors of geometry, stacking and electrode design will prove to be deciding factors when contemplating the use of CNT-polymer based actuators for any type of functional model.
The final aim of this poster will be to highlight the engineering factors involved for an optimum behaviour of actuation. Thus it will be shown that incorporating scientific findings with engineering principles gives the possibility to adopt CNT-polymer actuators for use in current and future applications to be one step closer.
