The bending actuator is fabricated by depositing a thin conductive polymer layer of poly 3,4-ethylenedioxythiophene: PSS, better matched with LSCE liquid crystalline elastomers as artificial muscles robotics compared with metals or inorganic nanoparticles used in other approaches, allowed us to develop an all-organic reliable millimetre-scale actuating composite.
The LSCE and the composite material are characterized as regards their thermo-mechanical and liquid crystalline elastomers as artificial muscles robotics properties.
A model is introduced to describe bending of the composite as a function of the thermo-mechanical properties of the LSCE, and the model is assessed by comparing the model results with the experimental findings. Bending actuation via direct Joule heating of the composite is also assessed by supplying the necessary current 50 mA at 1. These results open new possibilities for the application of LCEs in the micro and soft robotics fields, as well as in the biomedical field.
