Just listen to the chaos: A new approach to extracting information from large ensembles of sensors

Nanowerk  January 24, 2022 In distributed sensing approaches where readouts are obtained directly at the ensemble level, generally requires sensor nodes capable of interacting with each other to implement the required readout statistic. An international team of researchers (Japan, Italy) developed an experimental set up based on chaotic synchronization. They found single-transistor oscillators, representing remarkably low-complexity yet highly flexible entities to be suitable for wireless coupling via mutual induction, realizing a simple form of telemetry for luminous flux. Using numerical simulations and numerous laboratory experiments they demonstrated a rich repertoire of possible interactions among multiple sensor nodes and between the same […]
