Abstract: Embodiments related to a haptic actuator for transmitting heat and/or mechanical vibrations to an adjacent surface are disclosed. The haptic actuator may include a heating membrane, one or more supports, and a body. The one or more supports may extend between the body and the heating membrane to physically separate the heating membrane from the body.

Abstract: A device for manipulating the temperature of a surface may include a heat transfer surface including active portions and a passive portion. The passive portion may include an inner passive portion disposed between each of the active portions and/or may include an outer passive portion that may surround each of the active portions. The active portions may form 40-90% of a total surface area of the heat transfer surface, where total surface area includes active portions and an inner passive portion. The passive portion(s) may have a thermal conductivity less than the active portion. A processor may be in electrical communication with thermoelectric modules defining or forming the active portions to generate a heat flux through the heat transfer surface. The heat flux through the active portions may be between 500 and 15,000 W/m2 during nominal operation of the device.
