Cornell develops the tiniest walking robot, enabling precise imaging and force measurement at the scale of microscopic biological structures.
The team claims the robot can navigate specific locations, such as tissue samples, to capture images and measure forces at the scale of the body’s smallest structures.
The innovative design allows the robots to move autonomously, making it possible to reach precise targets for imaging and measurement. By leveraging magnetic fields to control their emotions, the researchers have achieved precise manipulation of these tiny devices.The breakthrough combines untethered robotic mobility with advanced optical imaging, fulfilling the dual requirements of matching the scale of light wavelengths and ensuring independent movement.
“The miniaturization of robotics has finally reached a point where these actuating mechanical systems can interact with and actively shape light at the scale of just a few wavelengths – a million times smaller than a meter,” said Francesco Monticone, associate professor of electrical and computer engineering in Cornell Engineering and co-author of the study, in aTo drive robots at the microscale, researchers patterned the devices with nanometer-scale magnets featuring two distinct shapes: long...
