Programmable Materials Create Multistable Motor-less Finger for Robotics
A programmable metamaterial finger can lock into four positions without electronics, offering a simpler and more functional future for prosthetic hands.
A new finger joint made from a single piece of programmable metamaterial could simplify the design of hand prostheses and robotic grippers, providing users with greater comfort, aesthetics, and functionality at a lower cost.
The system, developed within the Fraunhofer Cluster of Excellence Programmable Materials CPM, can hold four stable positions without motors or multiple interconnected parts, moving away from conventional prosthetic designs that rely on screws, hinges, and extensive assembly.
Researchers from several Fraunhofer Institutes are working together on the “ProFi” (Programmable Multistable Finger) project.
