AI Article Synopsis
- Electroactive polymers (EAPs) are gaining interest in various fields like robotics and biomedical devices but face challenges such as incomplete reversibility and high voltage requirements.
- A new actuator using a carbon nanotube yarn infiltrated with elastomer and methanol shows improved performance by achieving a substantial work capacity of 0.49 kJ/kg and a tensile contraction of 30.5% at a relatively low voltage of 5 V.
- This design demonstrates the potential for practical applications in soft robotics, outperforming natural muscle capabilities significantly.
Article Abstract
Electroactive polymers (EAPs) have attracted attention in many fields such as robotics, sensors devices and biomedical devices. However, the practical application of these actuators has still problems due to incomplete reversibility and high applied voltage. In order to overcome these problems, in this study, we have shown actuator based on phase transition that is consisted of the carbon nanotubes yarn infiltrated with the mixture of elastomer and methanol. Our electrothermally driven hybrid coiled yarn muscle provides a work capacity of 0.49 kJ kg and a tensile contraction of 30.5% within ∼3 s on an applied stress of 3.1 MPa at an applied DC voltage of 5 V. The maximum work capacity is under isobaric 23.4 MPa, which is 110 times that of typical mammalian skeletal muscles. This actuator may serve as a promising candidate for the practical use in soft robotics.
