Submitted Abstract
The main goal of the experimental PRCI research project HARVESTORE is to develop a compact versatile vibration energy-harvester power source and energy storage devices based on nanomaterials, nanostructuration and functionalization and their integration, thanks to a specific electronic system, for industrial applications. HARVESTORE will allow minimal invasive installation of Health and Usage Motoring System (HUMS) with many possible use cases (motor, car, aircraft, helicopter rotors, gearmotors, agricultural machinery, industrial conveyor belts, etc.). The proposed system will consist of three unique features, namely an electrically-tuneable piezoelectric energy harvester, an original co-integration of flexible battery and super-capacitor for high-density energy storage, a dedicated versatile ASIC for harvested power management and sensor signal processing. The work program of HARVESTORE is composed of 5 work packages.WP0 concerns the management and sdissemination issues. WPs 1 to 4 are more technical. WP1 “Vibrating energy tuneable transducer”(LIST) concerns the design and production of the vibrating energy tuneable transducer in charge of producing the power for the whole module. WP2 “Energy storage”(LPICM) concerns the integration of the nanomaterials based super-capacitor with the battery, including original architectures for both devices. This work package also deals with the development of a hybrid super-capacitor, which would replace both the super-capacitor and the battery. WP3 “Dedicated Integrated Electronics and Signal Processing for Vibration Sensing and Energy Harvesting”(ICube) concerns the power-efficient-aware integrated electronics in charge of the managing the whole harvesting module. WP4 “Use-case test vehicle Specifications/Exploitation” (TRT) identifies the application-oriented specifications for WP1 to WP3 and puts together the outcomes of these WPs to validate the module proposed by the HARVESTORE project. The real added value of the project is also due to the fact that all the devices are conceived/fabricated together, in parallel to be conveniently integrated in an effective system. Indeed other teams have developed single devices but at our knowledge HARVESTORE constitutes one of the first projects really targeting a full integrated system of more devices based on nanomaterials developments with embedded electronics.
