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 a plurality of electronic sensory to detect a trigger signature from a sensory stream of a sensor to be monitored from among the plurality of electronic sensors as indicated by an application, 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, and wherein an interconnect allows configuring the capturing element and the classifying element into structures defined for the trigger signature, the structures each comprising a plurality of neurons having defined neuron parameters; (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; (c) after step (b), upon the reconfigurable event driven hardware detecting the trigger signature, communicating details of the trigger signature to the processor, and invoking the application in response to the communication; and (d) reconfiguring the reconfigurable event driven hardware to detect a different trigger signature from the sensory stream during runtime of the application in response to a chance from the application.
