Many buds to a blossom: A synchronization approach to sensing using many oscillators
(PHYSorg.com Physics)

Engineers at the Tokyo Tech have found a new approach to taking a measurement over an extended area. The technique is based on coupled chaotic oscillators, which are highly sensitive electronic circuits that can interact wirelessly through low-frequency, low-power electromagnetic coupling. By making each oscillator sensitive to a quantity of interest, such as light intensity, and scattering a number of them sufficiently closely, it is possible to read out useful measurement statistics from their collective activity.
