A Soft Material that Moves When Exposed to Light Could be Ideal for Robotics

When exposed to non-uniform light, the SP-BZ gel moves. This diagram shows how the material moves over time when only the ends are exposed to light. (Photo Credit: University of Pittsburgh)

Researchers at the University of Pittsburgh’s Swanson School of Engineering have designed a synthetic polymer gel that can generate enough chemical energy to shape-shift and propel itself forward. The researchers modeled their research after the single-celled organism euglena mutabilis, which processes energy to expand and contract …
