High-Performance Ionic Polymer Mechanotransducer for Soft Tactile Feedback |
| 초록 |
With the development of soft electronics, an ionic electroactive polymer (i-EAP) actuator is spotlighted as a promising candidate due to a lot of advantages such as flexibility and low driving power. However, they suffer from low blocking force, displacement, and narrow bandwidth under electric field. In this talk, we propose an ionic polymer mechanotransducer (IPM) showing wide bandwidth of over 100Hz and high blocking force based on ionic PEDOT:PSS electrode and ionic polymer dielectric with fibrillar nanostructures for effective tactile feedback. As a result, the IPM was successfully operated with a large displacement up to 2.5mm at an operating frequency of 20mHz under an applied voltage of 2V. Further, the IPM shows large blocking force of 0.4mN at operating frequency of 1Hz. These our actuator is capable of driving up to a high frequency of 200Hz and shows an improved blocking force up to 0.4mN. |
