In harvesting RF energy from the ambient source, Radio Frequency (RF) plays an important role for zero energy IoT devices. Current research focused on 4G/5G technologies, however, after the concept of Artificial Intelligence (AI), Virtual and Augmented Reality (VAR), Three-Dimensional (3D) media, Internet of Everything (IoE), multi-way virtual meeting with holographic projection, brain communication interface, remote surgery and digitalize the whole word, 6G has got a great attention of the researchers because of latency, reliability and data rate requirements of 4G/5G systems. Several technologies companies such as Ericson and MIT started to work on 6G zero energy devices. Energy harvesting is an open research challenge in 6G technology due to latency, reliability and data rate requirements in 4G/5G technology. In this paper, we have conducted a real-world experiment on Power cast energy harvesting zero energy devices and examined the behaviour of sensed data in different scenarios, such as indoor/outdoor, distance (feet/ meters), and directions. In addition, an overview of different electricity generated methods is presented to better understand the energy and energy harvesting techniques. Furthermore, we have obtained results for these scenarios and show that this technology has a promising future in 6G.
