  • Thermal switch using moving droplets
    Patent number: 9010409
    Abstract: A thermal switch has a first substrate, a thermally conductive region on the first substrate, a thermally insulative region on the first substrate adjacent the thermally conductive region, a second substrate arranged adjacent the first substrate, a droplet of thermally conductive liquid between the first and second substrate adjacent the thermally conductive region and the thermally insulative region, and an actuator arranged on one of the first or second substrates to cause the droplet to move between the thermally conductive region and the thermally insulative region on the first substrate.
    Type: Grant
