Examination of Emerging Haptic Tactor Technology

Existing tactile display technology is too large, and too delicate for many SOF uses. In addition, it is not suited to working underwater in non-magnetic applications. Pneumatic tactors already meet SOF requirements, but existing drivers for this type of tactor have used electric motors or voice coils, with an associated large magnetic field. The proposed work will focus on the further development of pneumatic tactile display technology to include drivers which are powered by compressed gas, and controlled through piezo-electric valves, so that magnetic signature of the system is practically zero. Additionally, we will address the subjects of size and ruggedness. A combination of theoretical considerations, supplier information, and laboratory tests will confirm that the conceptual design presented will meet expectations.
