Description
Nowadays, GPS trackers for railway applications are powered by batteries. Some companies offer first vibration harvesters to power such trackers during operation to get rid of batteries or to prolong operation times.
In a previous Enables TA project the general approach of using energy harvesting from vibrations for powering GPS trackers on railway trains was investigated. Vibrations on trains were recorded and analysed and commercial vibration harvesters were characterized in the lab.
In this project, a selected vibration harvester was integrated onto GPS trackers to cover parts of the power consumption and extend the operation time of the battery. The GPS tracker with the vibration harvester was characterized with vibrations from preceding field tests in the lab to record the output power and to investigate under which condition a self-powered operation of the GPS tracker was possible.

“Very smooth process from first contact. Availability of Fraunhofer IIS was really good. Answers and technical input were punctual and very accurate. Very direct collaboration, the agenda of the project and the setup was clear to everyone. In addition, two-weekly conference calls helped to fulfill the aim of the project.”

“Thanks to the EnABLES team and the EU for supporting my project!!! This is an amazing transnational program that provide little companies like mine to access billions of dollars in assets that never would have been available/affordable for us. Hope it continues and grows for others as well as our desire to utilize in the future. Thanks again for putting your resources to great use!”

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
The goal of the project was to investigate energy harvesting power supplies for GPS trackers on railway trains. A GPS tracker was used in a field test to evaluate the power consumption of given railway use-cases and to record and characterize the typical vibration spectrum in this environment. The power output from off-the-shelf vibration harvesters was characterized with the vibrations from the field tests. Further lab testing was analyzing the performance of the vibration harvesters and an appropriate energy management system to power the tracker in the specific use-case was customized.

Description
The study investigated whether RFID technology can be used to wirelessly monitor the temperature of heated food in a combined device consisting of an oven and a microwave. The wireless sensor transponder should be supplied with energy via an independently transmitted electromagnetic field (microwave signal, 2.45 GHz) and the sensor transmits data to a separate receiver station, called reader. The investigations were carried out on the basis of simulations. The simulations were carried out with the 3D simulation program “Microwave Studio” from the company “CST” on a 3D model.
The supply of the transponder and the data transmission procedures were simulated separately. To estimate the transmission factor, a theoretical preliminary consideration was carried out. A transponder antenna and two reader antennas were designed for the microwave. With these antennas the transmission factors were simulated and evaluated with different parameters.
Results
It became clear that the metal surrounding of the oven has a great influence on the matching of the antennas. The presence of water and materials that contain a high degree of water have a very high absorption and leads therefore to losses. This plays a big role for the transmission and the adjustment of the antennas. The varying positions and volumes bring different results, so that these cannot be estimated by simulation for all occurring cases of positions and volumes in the area of interest.
After theoretical preliminary considerations and a detailed parameter study derived from them, the transmission factor shows a worst-case value -64.5 dBm for the supply path and -61 dBm for the data transmission path. Nearly all simulation results meet these values. Individual scenarios at a critical position of the sensor show the transmission factor below -60 dBm. However, this value was chosen somewhat more conservatively. With a typical receiver a robust data transmission is possible with receive signals down to -90 dBm.

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.
