RAPID HEATING, COOLING AND MASSAGING FOR CAR SEATS USING INTEGRATED SHAPE MEMORY ALLOY ACTUATORS AND THERMOELECTRIC DEVICES |
摘要 |
An apparatus and method for providing controlled heating, cooling and motion, in a device such as an active robotic automobile seat, are disclosed. A shape memory alloy (SMA) element, which changes shape upon application of a temperature change to the SMA element, is coupled to a thermoelectric device. Heat flows through the TED upon application of an electrical current through the TED. The apparatus is operable in one of a plurality of modes. In a first mode, a current is applied through the TED to cause a temperature change in the SMA element to change the shape of the SMA element. In a second mode, a current is applied to the TED to cause heat flow in a space adjacent to the apparatus. By controlling application of current to the TED, controlled motion, heating and cooling are achieved in the seat. |
