Abstract
Mechanical metamaterial passive wireless sensors and methods of use thereof are disclosed. An example sensor includes a flexible substrate having multiple extending arms; at least one temperature responsive actuator coupled to the substrate; and an antenna embedded within the substrate and extending along at least a portion of the multiple extending arms, the antenna configured to deform with the substrate. The substrate may be configured to be activated upon exposure of the at least one temperature responsive actuator to an environmental temperature that exceeds a threshold, and further configured to transform into at least one three-dimensional configuration in response to a duration of immersion in a liquid following the activation, the three-dimensional configuration causing a detectable change in electromagnetic signal characteristics of the antenna.
