1. A method for analyzing a sensory stream from an electronic sensor in an energy-constrained environment, the method comprising: (a) configuring a reconfigurable event driven hardware in communication with the electronic sensor to detect a trigger signature from the sensory stream, wherein the reconfigurable event driven hardware includes reservoir computing implementing: (i) a capturing element configured to capture a temporal behavior of the sensory stream; and (ii) a classifying element configured to classify an output of the capturing element to identify the trigger signature; (b) placing a processor in a low power consumption mode while the reconfigurable event driven hardware monitors the sensory stream to detect the trigger signature; and (c) after step (b), upon the reconfigurable event driven hardware detecting the trigger signature, communicating details of the trigger signature to the processor.
