• Currently, researchers have increased their attention in Indoor Geolocation due to the exponential growth of the number of the Internet of Things (IoT) devices interconnected, because they might offer the possibility of monitoring the location of people, devices and tools in real time. Added to this, the high percentage of population in the world who live in cities makes Indoor Positioning Systems (IPSs) an interest topic for research. Most smartphones give the possibility to use navigation systems by satellite. However, their performance is limited in indoor environments because of the weakness of the signals. Therefore, interest has grown in looking for other technologies to implement these systems. Oneof these alternative technologies is Visible Light Communication (VLC) which is a type of optical wireless communication (OWC). In this context, Visible Light Positioning (VLP) systems have become a strategic solution to the traditional solutions based only on radiofrequency (RF). In this paper, we propose a low-cost, energy-harvesting hybrid RF-VLP system to implement geolocation applications for indoor environments. Its receiver consistsof a wearable based on Flexible Perovskite Photovoltaic (PePV) cells.
