Claim Text:
1. A cooling device, comprising: a first material that induces strain upon application of a voltage signal, in which a level of the strain varies in response to changes in the voltage signal; a second material coupled to the first material, in which strain is induced in the second material when the strain is induced in the first material, and in which an entropy and a temperature of the second material change when the strain is induced in the second material; a voltage signal generator to provide the voltage signal, in which the voltage signal is configured to cause the second material to vary between higher and lower temperatures; and an actuator to cause the second material to alternately move between a first position and a second position, and wherein the actuator causes the second material to move to the first position when the second material is at a relatively lower temperature, and causes the second material to move to the second position when the second material is at a relatively higher temperature.
