3D-Printed Structures Respond to Stimuli

Jan-19-19 3D-printed structures inspired by the Venus flytrap could use embodied logic to carry out complicated behaviors without motors or computers.

Developed by researchers at Penn State University, the structures were created using multi-material 3D printers to build complex structures with nested if/then logic gates. These gates and their actions can be triggered by simple environmental changes, such as water monitoring device that will only open to collect a sample in the presence of a specific pollutant. The devices do not require batteries or a computer, and could therefore remain active and in place for extended periods with no human interaction or maintenance.
