London : The precursors of miniaturised machines are here. Packed with instrumentation, these marble sized probes float freely under water, measure local temperatures to a millionth of a degree, and send the data back wirelessly.
Developed by researchers at the Université de Lyon in France, these mini machines will be released in large numbers to collect data on ocean currents and atmospheric winds, sciencedaily.com reported.
These machines have already been used to track the paths of tiny heat packets that travel through fluids, showing that the packets follow a regular pattern.
Researchers are hoping that the device will teach them more about the motion of particles in turbulent systems, including hurricanes and mixtures of reactive chemicals.
