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.

Abstract: A knitted structure is configured for heat generation and distribution. In some embodiments, the knitted structure includes a knitted fabric including a first knitted layer and a second knitted layer opposite the first knitted layer. The first knitted layer has a first thermal conductivity. The second knitted layer has a second thermal conductivity. The second thermal conductivity is greater than the first thermal conductivity to faciliate heat transfer toward the first knitted layer. The knitted structure may further include a plurality of electrodes at least partially disposed inside the knitted fabric. Each of the plurality of electrodes is configured to generate heat within the knitted fabric upon receipt of electrical energy in order to distribute heat along the knitted structure and toward the first knitted layer.

Abstract: A stretchable adjustable-stiffness assembly includes a casing and first and second friction layers. The casing can be fluidly sealed and includes an interior compartment containing a fluid. The fluid can shift between a first interior pressure and a second interior pressure less than the first interior pressure and an exterior pressure. The first and second friction layers are disposed within the interior compartment. The assembly can shift between relaxed and fixed configurations. In the relaxed configuration, the fluid has the first interior pressure, the casing is stretchable between a first dimension and a second dimension greater than the first dimension, and the assembly has a first stiffness. In the fixed configuration, the first fluid has the second interior pressure, the casing length is fixed, the first and second friction layers are engaged, and the assembly has a second stiffness greater than the first stiffness.

Abstract: A panel assembly includes a frame and a textile panel. The frame has a first member and a second member spaced apart from each other. The textile panel is attached to and extends between the first member and the second member. A tension controlling system is attached to the textile panel. The tension controlling system is reconfigurable between a first state for tensioning the textile panel to provide a first tensile force and a first maximum sag distance, and a second state for tensioning the textile panel to provide a second tensile force and a second maximum sag distance. The first tensile force is greater than the second tensile force, and the first maximum sag distance is less than the second maximum sag distance.

Abstract: A passive airflow regulation system for controlling temperature of a heat-absorbing subassembly is disclosed. The passive airflow regulation system includes a duct configured to provide a conduit for an incident ambient airflow to the heat-absorbing subassembly. The duct is arranged proximate to the heat-absorbing subassembly. The airflow regulation system includes a valve configured to control passage of the incident ambient airflow through the duct. The airflow regulation system also includes an actuator employing a phase-change element configured to selectively store and release energy in response to changes in temperature and stress. The actuator is arranged at the heat-absorbing subassembly and configured to select a position for the valve between and inclusive of fully-opened and fully-closed in response to a temperature of the heat-absorbing subassembly. The airflow regulation system can be arranged on a vehicle having a vehicle body including a first body end configured to face the incident ambient airflow.

Abstract: A dielectric elastomer actuator includes an elastomeric film and an electrode material layer on opposing sides of the film. The elastomeric film includes a first section, a second section, and a transition section disposed between the first section and the second section. The electrode material layers are disposed on the transition section and the first and second sections. The first and second sections are restrained in a pre-stretched configuration in an axial and a lateral direction, while the transition section is not restrained in the axial direction. The transition section elongates in response to the application of a voltage to the electrode material layers, such that the first and second sections move apart, in the axial direction. Likewise, the transition section is configured to contract in an absence of a voltage applied to the electrode material layers, such that the first and second sections move apart, in the axial direction.
