The untethered robot would be able to perform on-demand biomedical heating in remote parts of the human body, like the stomach and small intestine.
This millirobot has been created particularly for on-demand heating within the human body.Nature communications“The robot is actuated with a low-frequency magnetic field to the target location. Application of high-frequency magnetic field results in Joule heating of the metal plates. The heat energy can then be used to interact with the environment,” mentioned the study.
There are several ways to achieve remote heating inside the human body, including thermochemical, acoustic, photothermal, and“Magnetic actuation has emerged as a promising method for robots in biomedical applications due to the magnetic field’s ability to penetrate human tissues safely,” noted thePreviously, engineers demonstrated using soft magnetic robots based on solid metals to undertake less intrusive medical procedures. They did, however, have minimal medical usefulness.
Furthermore, the robot also hones certain sophisticated features, such as delivering medication cargo or other therapeutic applications onto tissues.
