“rever UV light then shone on the body for about a minute, the pyrrole inside the plastic turned into polypyrrole, an electrically conductive polymer. The synthesis of a new sensor was also evidenced visually, as the translucent body turned black. Elsewhere, it stayed unchanged. Using a stencil, the team could draw sensor patterns with 0.3-millimeter precision. The new material works as a UV receptor: when UV light hi”

“g beyond ordinary drift was going on," Pankratov says. The authors interpret this as a form of material memory: the sensor's structure becomes a record of what the robot has experienced. The sensors still worked after more than four months of storage. Time-lapse of the artificial circulatory system at work.

- Tech Xplore — RoboticsSignalRobot Moth Grows UV Sensor Using Artificial Circulatory System
Researchers from the University of Tartu and the Italian Institute of Technology developed a moth-shaped robot that uses an artificial circulatory system to deliver chemical building blocks and grow a light sensor where UV light strikes. The robot's body is 3D-printed with microchannels that allow fluid to flow, enabling the synthesis of a conductive polymer sensor. This approach allows the robot to create new hardware on-site, enhancing its adaptability to unpredictable environments.
