| 发明名称 | Refrigeration through voltage-controlled entropy change | ||
| 摘要 | A method for refrigeration through voltage-controlled entropy change includes applying a voltage signal to a piezoelectric material to generate strain in the piezoelectric material, generating strain in a magnetic material attached to the piezoelectric material, and generating a change in a temperature of the magnetic material in response to the strain in the magnetic material. | ||

| 主权项 | 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; and 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. | ||
