Robotic roots could be used to monitor changes in the soil, with sensors to measure nitrate, pH, water, temperature, and even gravity. Creator Barbara Mazzolai says they could also be used as a medical device. "The ability to bend, grow at low pressure and with low friction while adapting to the surrounding environment could offer a new vision for medical tools," she told New Scientist. Imagine vaguely tentacle shaped sensors growing inside you during surgery. Bleck! But also, awesome.
