Engineers of the Massachusetts Institute of Technology presented new miniature robots, which are so small that they can soar in the air, and comparable with the size of the human cell.
Researchers have committed a breakthrough by connecting two-dimensional electronics to solid colloids — microscopic particles from 1 to 1000 nm. The device is equipped with photodiode semiconductors with which it can function completely autonomously, working without a battery. Built-in systems can convert light to electricity, which is enough to ensure the operation of embedded sensors and storing the collected data.
Developers intend to apply them for environmental research in hard-to-reach places, such as a pipeline or human body. Devices can be simply scattered in the air and move along with it to the desired environment for further analysis. However, to get data from the robot, it is necessary to extract it after collecting information that it looks different in each individual system.
Engineers gradually reduce the size of the inventive devices, moving to microscopic dimensions. Recently created nanoscale
