Concomitance of radio frequency energy harvesting and wearable devices: A review of rectenna designs

Abstract

Passing through the transformation of wood to coal then to oil and gas, we find ourselves fortunate to witness the next major transformation, which will lead us to the "New Energy Era." Due to advancements in the field of electronics, energy harvesting has attracted great attraction from researchers and scientists to enhance portability and reliability with reduction in battery wastes. Moreover, wearable electronic devices are also becoming quite popular these days because of their usage in a broad range of applications like sports, health sciences, emergency, and so forth. In order to make sure smooth operation and to increase the working time span of these devices, it has become really important to bring wearable devices and radio frequency (RF) energy harvesting to the same platform. RF energy harvesting is one of the best suitable technology for wearable devices. The

Harnessing Energy for Wearables: A Review of Radio Frequency Energy Harvesting Technologies

“…These frequencies are utilised for wireless communications or radar signals. RF waves are generated when an alternating current passes through a conductive material [4]. They prove advantageous for wireless energy harvesting, enabling the wireless powering and operation of devices even in scenarios with limited RF energy available.…”
