Abstract:
1. A thermal switch, comprising: 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; at least two spacers between the first and second substrates to separate the substrates, the spacers located with the thermally insulative and the thermally conductive regions between the spacers; a droplet of electrically and thermally conductive liquid between the first and second substrates adjacent one of either the thermally conductive region and the thermally insulative region; and at least two electrodes arranged together on the second substrate to generate electrostatic forces that cause the droplet to move between the thermally conductive region and the thermally insulative region on the first substrate wherein a dielectric coating separates the electrodes from the droplet.
