  • Energy harvesting for sensor systems
    Patent number: 11489464
    Abstract: Described herein is an energy harvesting system comprising a transducer and a processor. The transducer generates an electric signal from ambient energy. The processor is configured to process the electric signal to perform pattern recognition of the electric signal so as to determine and output a characteristic of a source of the ambient energy. The pattern recognition comprises statistical analysis and frequency domain analysis.
    Type: Grant
    Filed: March 14, 2017
    Date of Patent: November 1, 2022
    Assignee: NATIONAL ICT AUSTRALIA LIMITED
