“The scope encapsulates the development of new circuit designs to achieve high harvesting sensitivity through Q-factor improvement. Efficiency enhancement can be achieved by reducing the forward conduction and leakage current of the RFDC rectifier (which converts RF energy into DC voltage) and reducing the power consumption of the power management unit,” he added.
“Perhaps, our new way of harvesting renewable energy can also replace the need for battery power to enable some smart devices or mobile apps. So, potentially, the results of our Collaborative R&D venture will be beneficial for high-volume mass market applications in various fields of technology,” he said.
According to him, this RF energy harvesting project has marked eight milestones as of April 2022.
I believe we have achieved good progress: we have already developed the tools to support energy harvesting from 2 RF ranges. The next stage is to look into harvesting energy from a 3rd frequency range”

“The two front-end circuits have been completed to include high-efficiency and high-sensitivity rectifiers and a re-configurable circuit capable of harvesting two frequency spectrums.”
Looking ahead, he said, the team also needs to consider the design and integration of a high-power conversion or efficiency charge pump.
“So, there is still much characterisation work to be done. When the proof of concept devices are back for characterisations, we should be able to finetune and create more robust and stable solutions,” he added.
“The deliverables include a fully developed prototype of a high-efficiency, integrated RF energy harvesting circuit capable of harvesting 3 RF frequency spectrums. We will then publish papers, and, hopefully, submit 2 IPs for patenting,” he added.
