Abstract
One embodiment of the invention includes a phase-change material switch. The switch includes a first terminal that receives an input signal and a second terminal. The switch includes an actuation portion that receives a control signal in one of a first state to emit a first heat profile and a second state to emit a second heat profile. The switch further includes a switch portion comprising a phase-change material arranged as a plurality of longitudinal strips that each interconnect the first terminal and the second terminal and that are each in proximity with the actuation portion. The phase-change material can be selectable between a conducting state in response to the first heat profile to conduct an input signal from the first terminal to the second terminal and a blocking state in response to the second heat profile to block the input signal from the first terminal to the second terminal.
