Heat and light for powering the Internet of Things

Harvestore is a 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 Novel Technique to Probe Physicochemical Processes In Situ

Researchers at CNRS, in collaboration with IREC, have developed a new technique for probing oxygen kinetics in-situ. The techinque is based on tracking the changes of isotope concentration in a material by Raman. The proof of concept and strengths of isotope exchange Raman spectroscopy (IERS) is demonstrated by studying the oxygen isotope back-exchange in gadolinium-doped ceria (CGO) thin films. Resulting oxygen self-diffusion and surface exchange coefficients are compared to conventional time-of-flight secondary-ion mass spectrometry (ToF-SIMS) characterization and literature values, showing good agreement, while at the same time providing additional insight, challenging established assumptions. IERS captivates through its rapidity, simple setup, non-destructive nature, cost effectiveness, and versatile fields of application and thus can readily be integrated as new standard tool for in situ and operando characterization in many laboratories worldwide. The applicability of this method is expected to consolidate the understanding of elementary physicochemical processes and impact various emerging fields including solid oxide cells, battery research, and beyond.

“Festa de la ciencia” 2023

Project partners from IREC have partecipated in the "Festa de la Ciencia" 2023 in Barcelona. A great outreach event to explain our activities and to introduce people to the power of harvesting heat and light! A very crowded event co-organized with another EU project "EpiStore", as you can see from the gallery pictures.
