Meta-Antenna and Energy harvesting/storage modules development for autarkic sensors arrays

Solutions developed

The EU-funded METATHERM project plans to demonstrate a versatile energy harvesting sensor array technology that can efficiently collect tiny amounts of energy from the environment. The novelty of the sensors will rely on the integration of an extremely compact, microwave antenna that incorporates metamaterials to further signal performance. The sun’s energy will be harvested using a novel ionic thermoelectric device. Pairing the energy harvesting device with a supercapacitor and a thermal energy storage system, METATHERM’s platform will allow continuous operation of the device. Project activities will pave the way for the development of high-efficiency, maintenance-free, self-powered sensors.

Main results

METATHERM introduces an energy harvesting and communication system for unattended environment sensors, enabling maintenance-free operation. Its key innovation lies in a microwave antenna utilizing metamaterials for high gain and compactness. Reduced power requirements facilitate novel energy harvesting methods, such as ionic thermoelectric devices harvesting solar energy efficiently. The system incorporates a supercapacitor and thermal energy storage for continuous operation. Leveraging manufacturing expertise from supercapacitors, METATHERM enhances the maturity level of ionic thermoelectric devices. The project aims to integrate these technologies into a single device and explore potential applications. An exploitation plan includes user engagement, application selection, and transfer strategies for market adoption.
