New Offer from CEA Liten

CEA-Liten has developed a new test bench for the characterisation of Peltier devices. With this new tool, temperatures of hot and cold sides of TEC (thermoelectric coolers) devices can be measured from room temperature up to 100°C. Current dependence of devices can be measured and thermal cycling can also be performed to quantify the TEC performances stability.

If you are interested, you can apply to use it, free of charge. You will find more information on this website:

Advanced Polymer Electrolytes Encompassing RTILs @PoliTO

GAME Lab @Polito) in collaboration with IIT – Graphene Labs and ENEA (Italy), Solvionic (France) and Helmholtz-Institute Münster and MEET Battery Research Center (Germany) have developed a binder-free electrode comprising of polycrystalline carbon-coated silicon nanoparticles encapsulated in few-layer graphene flakes coupled with a PEO-based crosslinked bilayer polymer electrolyte (BLPE).

A soft polymer electrolyte layer enriched with pyrrolidinium-based room temperature ionic liquid (RTIL) is deposited on top of the electrode and crosslinked in situ to achieve an optimal interfacial contact. A hard layer consisting of a crosslinked PEO-based polymer electrolyte film with a lower amount of the same ionic liquid is integrated with the electrode/electrolyte composite assembly ensuring shape-retention ability upon thermal stress. Proof-of-concept lab-scale Li-metal polymer cell demonstrates a reversible specific discharge capacity exceeding 1000 mAh/g, much higher than the corresponding RTIL-based liquid electrolyte, indicating the beneficial effect of crosslinked PEO-based polymer matrix, in the absence of any SEI-forming agent, over Si-based Li-ion battery electrodes.

Webinar #11: Wireless Power Transfer

The “RF and Inductive Energy Harvesting” webinar takes place on Wednesday 28th April and addresses the capture of energy from electromagnetic waves. The physical basics of this principle are explained. In low frequency ranges the principle of induction is mostly used. It will be shown this is suitable for energy transfer over short distances or close to current-carrying conductors. At higher frequencies, energy transmission also works over longer ranges, e.g. over several meters. The webinar will show which parameters influence the principle of transmission and will give tips for robust operation. Examples are used to show the possibilities for various applications e.g. in industry and medicine.

Join us on Wednesday 28th April at 15:00 CEST (UTC+2) when our research partners Peter Spies (Fraunhofer IIS), Gerd vom Bögel (Fraunhofer IMS) & Mahmoud Wagih (University of Southampton) will explain Wireless Power Transfer.EnABLES Webinar #11

Summer School 2021

We are delighted to announce that NiPS Laboratory and EnABLES will host the Summer School 2021. The Summer School is now scheduled to take place in Perugia in the week 15th-18th September 2021, in parallel with the International Conference SR40, relating to the 40th anniversary of the first paper about Stochastic Resonance.

The school is a great opportunity for graduate and PhD students, post-docs, young researchers and in general for all the scientists or professionals interested in the topics of energy transformation at microscales for IoT applications, such as energy harvesting, storage, micro-power management and systems integration. It is not only an occasion of learning from highly skilled professionals of IoT, but even an opportunity for encouraging collaborations and the comparison between different and complementary competences.

The event will be organised in a mixed modality in order to guarantee that the School will be carried out even if the limitations – due to the Covid-19 pandemic persist: virtual attendance or an in-presence participation. To learn more about the agenda please visit NiPS/EnABLES Summer School 2021
