Fully Oxide-based Zero-Emission and Portable Energy Supply (FOXES)

The project FOXES aims to provide a clean, compact, low-cost and scalable high energy density solution for powering IoT devices such as wireless sensor nodes. The energy supply system developed by FOXES is constituted by the combination of a lead-free perovskite solid cell and a multilayer relaxor thin film capacitor with high energy density. Coupling these two devices allows solar energy surplus to be stored in the capacitor and being used for periods of time when solar light is not available. The energy balance (intake/discharge) is regulated by an electronic circuit, ensuring a positive energy balance for powering the sensor node.

A clean way to power wireless IoT devices

In recent years, the Internet of Things (IoT) has enabled the communication and interaction between different devices. Such devices play a big role in the development and manufacturing processes for vehicles and machines; therefore, they need to be small, lightweight and wireless. The EU-funded FOXES project will develop a clean, compact, low-cost and scalable high-energy density solution for powering IoT devices such as wireless sensor nodes. More specifically, the proposed system will combine a high-efficiency solar cell with a multilayer capacitor and an energy management circuit, minimising the use of harmful materials and improving recyclability and end-of-life disposability.
