Robot moth grows new sensor using its own blood

Robot moth grows new sensor using its own blood

Summary

Engineers at the University of Tartu and the Italian Institute of Technology developed a moth-shaped robot that can grow new sensors by pumping pyrrole-containing fluid through its 3D-printed body and exposing specific areas to ultraviolet light, which converts the plastic into conductive polypyrrole. The prototype demonstrated sensor growth after UV exposure, with sensitivity increasing over repeated exposures, though it remains limited by non-reversible reactions, external power requirements for wing actuation, and stencil-defined patterning rather than autonomous environmental response.

That liquid carries pyrrole, a chemical that turns into an electrically conductive plastic called polypyrrole when it's hit by UV light, with help from a light-activated additive. Using a stencil, the team picked which patch of the wing to light up, and that patch turned black. Veins

The sensor still worked after four months in storage, and it grew more sensitive with every exposure as leftover pyrrole went on reacting, although it takes about five minutes to settle back after each flash of UV. Still, the robo-moth is just a prototype, and it comes with a set of limitations that keep it far from the real
