- developed an Radiofrequency technique that transforms atmospheric energy into energy for IoT devices.
- Developed from Aug 2020 to Sept 2023, this technology boosts energy reliability &, conservation
Although mobile devices and Internet of Things ( IoT ) applications are becoming more common, keeping them charged is still a challenge. Researchers and industry leaders are looking into new ways of energy harvesting and developing novel charging options besides conventional power outlets.
This vision is becoming a reality in Malaysia, thanks to a collaboration between Infinecs Systems Sdn Bhd, Universiti Malaya, Asia Pacific University of Technology and Innovation, Universiti Sains Malaysia, and the Collaborative Research in Engineering, Science and Technology ( CREST ) Project. They have collaborated to create an innovative solution that transforms ambient radio frequency ( RF ) energy into usable electrical power for IoT devices, an Integrated RF Energy Harvesting System. Developed between August 2020 and September 2023, this discovery systems enhances energy efficiency and sustainability.
The system has a higher awareness that allows it to get energy from three different frequency bands, ensuring versatility, and an extended fluid range that allows efficiency to be maintained perhaps from poor RF signals. Additionally, it optimizes power storage and change for better performance.
The effectiveness of cooperation between academia and industry is demonstrated by this job. The Analog, Digital and RF Research Group, led by myself, along with contributions from Dr Lian Wen Xun and Dr Yong Jack Kee, played a key function in its development. Help from CREST, Infinecs, UM, APU, and USM was instrumental in bringing this technology to existence”, said Dr Ir Harikrishnan Ramiah, mind of the Centre of Research Industry at Universiti Malaya and director for the job.
He noted that overcoming a number of professional difficulties was necessary to create an RF energy harvesting system that could effectively convert RF power across many songs. ” This was achieved through strenuous study, extensive tests, and close cooperation between scientific analysts and industry specialists”, he said.
Another key problem was integration—seamlessly combining parts such as the RF front-end, converter, and cost pumps into a single program. ” We addressed these issues through careful architecture and optimisation”, Harikrishnan added.
The program has largely good industry feedback, and there is a lot of interest in its ability to provide self-sufficient, green power solutions for IoT devices. The renowned Major In Tech Innovation Award for Most Powerful Academia-Industry Collaboration has been given an additional recognition for its effects.
Looking back, the team is actively pursuing commercialism, targeting programs in 5G contacts, IoT sensors, biological wearables, and RFID. ” We even plan to continue R&, D efforts to enhance the state’s functionality, performance, and flexibility. According to Harikrishnan, the future work includes integrating it with 5G Wireless Sensor Networks ( WSN) and co-designing antennas and rectifiers to reduce system complexity and improve overall performance.
