Heat and light for powering the Internet of Things

Harvestore is a new European project for the development of beyond-state-of-the-art technologies in the field of Internet of Things.
Our “μ-harvestorers” will be able to collect and store energy from heat and light at the same time, in order to serve a whole family of new-generation portable devices. They will be powerful, small, and environmental friendly.


Harvestore puts together some of the main actors of science and technology across Europe. Research, technology centers and advanced industries from 6 different countries have joined their efforts with the goal of opening-up a new technology paradigm in the world of IoT.

At the edge of science and technology

Nanoioncs and Iontronics

With Harvestore, we will fabricate new artificial materials with superior performance. Fast electrical conduction and high charge storage capacity will be achieved by taking advantage of nanoscale engineering.

Silicon Integration

Advanced science and mainstream fabrication techniques will be bridged by the use of silicon technology. Silicon combines unique properties of manufacturability, abundance and low environmental impact.


A high-entropy nanostructure for Solid Oxide Cells

New paper: "A high-entropy manganite in an ordered nanocomposite for long-term application in solid oxide cells"

A new Nature Communications paper entitled “A high-entropy manganite in an ordered nanocomposite for long-term application in solid oxide cells” is released today, May the 11th, 2021. The research has been led by IREC. The paper is a collaborative effort between IREC, University of Cambridge (UK), Colorado School of Mines (USA), Coventry University (UK), ICN2-CSIC-BIST (Spain), Purdue University (USA) and Imperial College London (UK).

The communication reports on the development of a novel class of functional materials with enhanced electrochemical properties based on nano-engineered composite oxides.

The researchers realized vertically aligned nanocomposites of an ionic and an electronic conductor with straight applicability as functional layers in solid oxide cells. The ordered structured is characterized by a coherent, dense array of vertical interfaces at the nm-scale. The synergy between the two materials results in high electrochemically activity and superior thermal stability. The authors use a combination of state-of-the-art and novel techniques including physical vapour deposition, atom-probe tomography combined with oxygen isotopic exchange, density functional theory calculations, to disclose the exciting properties of the material and to highlight the relevance of local disorder and long-range arrangements for functional oxides nano-engineering.

Webinar on battery technologies and patents

On April 15th, the project will host the presentation of the EPO-IEA study "Innovation in batteries and electricity storage – a global analysis based on patent data", followed by round table. The study is a global analysis of energy storage technologies based on the patents filed in the last 20 years and highlights the trends in terms of applications, materials, forthcoming technologies. We will host one of the authors and we will discuss the directions of the innovation in the field with main actors of battery research and technology.
Confirmed list of speakers: Dr. Z. Georgiou (EPO director), Dr. A. Aguadero (Imperial College), Dr. G. Gregori (EPO Patent examiner), Prof. A. Tarancón (IREC), Dr. P. Vereecken (IMEC), Dr. C. Villevieille (CNRS). Click here for the final program.
