Abstract:
Presented herein are active textile structures with selectively variable surface friction characteristics, methods for making/using such structures, and vehicle components fabricated with electronically controlled textile structures with modifiable surface friction characteristics. An active textile system for governing frictional force levels at an interface with a user or object is presented. The system includes a textile structure that is fabricated from interlaced first and second textile filaments. Each textile filament has a respective texture that exhibits a distinct coefficient of friction. The textile structure has an outer and/or upper contact surface at the interface with the user/object. An actuating element, which is connected to the textile structure, is operable to selectively transition the textile structure between first and second states. The first state includes the first textile filament defining the textile structure's outer contact surface, whereas the second state includes the second textile filament defining the outer contact surface.
