Tiny robots help deliver precise amounts of medicine into the body

The tiny magnetic ultrasonic robot, just 1.3 mm wide and weighing 4.6 milligrams, can detect and adjust parameters such as force, vibration, viscosity and temperature via wireless connection.

A team of Chinese scientists has succeeded in combining sensing and control functions into a tiny device, opening up the possibility of delivering drugs into the body at precise doses while monitoring the body's response on the spot.

Researchers from the Huazhong University of Science and Technology in Hubei Province and the Chinese University of Hong Kong (China) have developed a tiny magnetic ultrasonic robot, just 1.3 mm wide and weighing 4.6 milligrams, that can detect and adjust parameters such as force, vibration, viscosity and temperature through wireless connection.

Thanks to its ability to detect stimuli and convert them into ultrasonic signals, the robot can manipulate delicate objects such as salmon eggs, as demonstrated in an animal model test.

Researchers are continuing to demonstrate that the robot’s thermometer version can sense temperature changes in pigs, while the capsule version has proven its ability to deliver precise doses of liquid into rabbits’ stomachs, as well as measure the dose over time.

Success from new experiments is paving the way for practical applications of this tiny smart device.

The research results have just been published in the scientific journal Science Robotics./.
