1. A device, comprising:
an enhanced magnetorheological elastomer (MRE);
an elastomer;
a first conductive knit fabric; and
a second conductive knit fabric; wherein:
the enhanced MRE has a folded pattern;
the enhanced MRE is embedded in the elastomer;
the first conductive knit fabric is disposed at a first end of the elastomer;
the second conductive knit fabric is disposed at a second end of the elastomer;
the first conductive knit fabric and the second conductive knit fabric are configured to output a voltage between the first conductive knit fabric and the second conductive knit fabric, wherein the voltage is generated by the enhanced MRE based on a strain induced on the device in response to deformation; and
the device is configured to fit around an object.
