What if the testing done at hospitals
could be conducted in the
patient’s home, office, or car?
Scientists foresee a time when medical
monitoring devices are integrated
into the human body to track vital
signs. But electronics are too rigid.
Researchers at Northwestern University developed a design that allows
electronics to bend and stretch to
more than 200 percent their original
size. The key is a combination of a
porous polymer and liquid metal. A
highly porous 3D structure was created
using a polymer material, poly(dimethylsiloxane) (PDMS), that can
stretch to three times its original size.
Then they placed a liquid metal
(EGaIn) inside the pores, allowing
electricity to flow consistently even
when the material is excessively
stretched. The result is a material that
is both highly stretchable and extremely conductive.
