Abstract
A stretchable sensor includes a stretchable layer including an elastomer, and a conductive layer at least partially buried in the stretchable layer and including a conductive nanostructure. The stretchable layer includes a plurality of first regions including a ferromagnetic material buried in the elastomer, and a second region excluding the plurality of first regions.
Claims20
A stretchable sensor, comprising:
- a stretchable layer including an elastomer;
- and
- a conductive layer at least partially buried in the stretchable layer, the conductive layer including a conductive nanostructure,
- wherein the stretchable layer includes
- a plurality of first regions including a ferromagnetic material buried in the elastomer, and
- a second region excluding the plurality of first regions.
3 more elements
A method of manufacturing a stretchable sensor, the method comprising:
- preparing a mixture including a ferromagnetic material and an elastomer precursor,
- applying the mixture on a first substrate to form an uncured stretchable layer,
- burying at least a portion of a conductive layer including a conductive nanostructure in the uncured stretchable layer,
- self-aligning the ferromagnetic material in the uncured stretchable layer to establish a self-aligned ferromagnetic material, and
- curing the uncured stretchable layer to form a stretchable layer including a plurality of first regions including the self-aligned ferromagnetic material and a second region excluding the plurality of first regions.
