At Florida Atlantic University, researchers have developed a new bionic finger that is soft and has movements like real finger. Researchers have created this robotic finger with the help of shape memory alloy (SMA), 3D CAD model and 3D printer. They have also used a new thermal technology that trains the synthetic phalange to utilize an extensive motional berth.
Researchers have developed two molds by using 3D printer and they placed two long alloy plates inside the molds. These plates respond to heat and allow the fingers to return to the original shape even they get bent. One plates let the finger straighten up, while other let it bends when heat is applied.
Erik Engeberg, the team leader said, “We have been able to thermomechanically train our robotic finger to mimic the motions of a human finger like flexion and extension, Because of its light weight, dexterity and strength, our robotic design offers tremendous advantages over traditional mechanisms, and could ultimately be adapted for use as a prosthetic device, such as on a prosthetic hand.”
During the testing of the robotic fingers, researchers applied heat via electric currents. The robotic finger is very soft and works pretty fine. The researcher’s team has said that they will use this tech for underwater robots. Want to know more about this project, click on the Team’s journal.
