Description
Current SiGe materials used in our thermoelectric modules are made using the RGS proprietary crystal growth process, which allows materials of controlled composition to be produced at industrial scale. Although the stability of the Thermagy technology is demonstrated, the relatively high costs of Ge limits the range of application of the modules to specific applications.
The objective of this research is to improve the thermoelectric performance of the materials and to allow reducing the germanium concentration. Both effects will have a positive impact on the module costs and will allow widening the market for our Thermagy modules.

Description
Enervibe is developing a unique Vibration Energy Harvester (VEH) which may change the electromechanical coefficient such that the VEH may tune to maximum energy extraction in real time. This property is equivalent to changing the piezoelectric properties of a piezoelectric based VEH which is clearly not possible. Such capability allows smaller VEH with higher power conversion per chip volume.
We plan to design an ASIC that will sample the VEH properties and will feedback a command for tuning the VEH to a maximum harvested energy.

Description
As the millimetric frequency range is gaining increasing interest to fulfill the need for ubiquitous Internet of Things (IoT) appliances, it is important to have efficient harvesters even at extremely high frequencies. The tunnelling diodes pose as good candidates with fast switching times. However, even the recent trials in the literature demonstrate limited efficiency for the measured devices. In fact, the reasons for this shortcoming are manifold and vary from understanding of the physical model to inaccurate fabrication process at the nano scale.
In this project, the physical design of the diode will be guided by the desired figures of merit (FOM) such as asymmetry, nonlinearity, and dynamic resistance set by the design. Then, a heuristic search for the optimum solution will be implemented to minimize the output of a fitness function. The final goal is an integrated software/hardware design approach to fabricate power-efficient multi-insulator tunnelling diodes for future 5G/IoT RF energy harvesting applications.

Description
Silicon is a potential anode material for lithium-ion batteries (LIBs). However, it undergoes a 400% volume expansion during lithiation/delithiation processes which damages the electrode integrity and leads to failure of the battery. To improve the electrode integrity, silicon based composites needs to be developed. In this project, we will electrochemically develop silicon composites from ionic liquids which will be directly used as anodes in LIBs without the addition of binders or other conducting materials. The influence of deposition temperature on the deposit morphology and crystallinity will also be evaluated.
To assess the battery performance and understand the chemical/electrochemical reactions as well as integrity of the electrode, various in situ and ex situ characterisation techniques will be used. Based on the obtained results and its optimisation, a full-cell will be constructed with silicon composite anode as a proof-of-concept.

Description
During the processing of food (e.g. roast) in a home appliance oven, a core temperature sensor allows to automatically control the cooking process. Typically those sensors are connected with cables to a plug that lies inside the oven chamber.
The aim of this work is to study if it is possible to power a microelectronic sensor by RF. The sensor should be in a stick shape and the RF signal should be radiated from an antenna inside of the oven.

Description
The development of high-capacity, high temperature resistant thin film batteries demonstrates very strong interest from different markets. Our company has developed new type of cathode materials with high storage capability of Li ions and new design of the energy storage device. In order to evaluate the full capabilities of our device we need to deposit anode layers composed of Li metal and Cu current collector as well as pack the device. We will work together with CEA-Leti on the synthesis and investigation of our energy storage device.
