This invention is directed to functional ionic liquid hybrid materials having negligible vapor pressure, nonflammability, good room-temperature ionic conductivity, wide electrochemical windows, and favorable chemical and thermal stability. The wavelength selection optics of a first preferred embodiment include a birefringent Brewster window enclosing the laser gas volume of the discharge chamber. The at least two traction cross members are attached to a top side of the traction layer along a length thereof. The system can be used to induce hypothermia in selected regions of the brain when used. The sensor element can be provided as a separate component, or in an especially preferred embodiment, the actuating element is simultaneously used as the sensor element as well.
