Abstract
A sensor, comprising a deformable substrate, comprising a structural metamaterial in a first configuration; a plurality of raised structures disposed throughout the substrate, wherein the plurality of raised structures are invertible; a responsive material layer, wherein the responsive material layer is disposed on the plurality of raised structures and is configured to invert the plurality of raised structures in the presence of an external stimuli; and a plurality of second configurations of the deformable substrate that correspond to a plurality of inverted raised structures.
Claims9
A sensor, comprising;
- a deformable substrate, comprising a structural metamaterial in a first configuration;
- a plurality of raised structures disposed throughout the substrate, wherein the plurality of raised structures are invertible;
- a responsive material layer, wherein the responsive material layer is disposed on the plurality of raised structures and is configured to invert the plurality of raised structures in the presence of an external stimuli;
- and
- a plurality of second configurations of the deformable substrate that correspond to a plurality of inverted raised structures.
A method for using a sensor, comprising;
- subjecting a sensor to an external stimuli, the sensor comprising;
- a deformable substrate, comprising a structural metamaterial in a first configuration;
- a plurality of raised structures disposed throughout the substrate, wherein the plurality of raised structures are invertible;
- a responsive material layer, wherein the responsive material layer is disposed on the plurality of raised structures and is configured to invert the plurality of raised structures in the presence of the external stimuli;
- and
- a plurality of second configurations of the deformable substrate that correspond to a plurality of inverted raised structures;
- inverting one or more of the raised structures in response to the external stimuli;
- and
- recording a spatial and sequential memory corresponding to the second configuration of the sensor.
