Periodic Reporting for period 1 - ASSET (The next generation of Antenna Structures Suited for Energy harvesting and signal Transmission in miniaturized chips for use in medical devices)
Berichtszeitraum: 2021-01-04 bis 2022-03-03
We have developed ONiO.zero - an ultra-low power wireless MCU (microcontroller unit) that uses energy harvesting technology. This means that ONiO.zero solely operates on energy from its surroundings - radio frequency (RF), solar, thermal, kinetic energy, etc.
The ASSET project focuses on the development of antennas for our technology platform - encompassing both energy harvesting and data transmission, potentially for a wide range of sensor types. These antennas will be a transversal component of ONiO’s batteryless solutions.
The main results achieved in the project include a wide array of antenna datasets and new antenna designs produced with the assistance of machine learning techniques. Furthermore, several antenna prototypes have been fabricated and tested in the lab, showing solid performance as well as good agreement with simulations and predictions from the design phase. Finally, RF energy harvesters were designed, tested and evaluated. These were embedded in the antennas to reduce the losses and improve the energy harvesting efficiency. These results will be described in two scientific articles (one submitted; one in preparation). Other means of dissemination included two articles published in ONiO’s website and shared across social media platforms.
